Cystic lesions of the maxillary sinuses include cysts, polyps and neoplasms. Maxillary sinus cysts are benign lesions that are commonly an incidental finding during X–ray, since any symptoms do not accompany their presence. An urgent problem is the development of differential diagnostics, the determination of indications for surgical treatment and the optimal treatment tactics for patients with cystic lesions of the maxillary sinuses. The authors describe their experience in patient management with maxillary sinus cysts. 175 patients (mean age — 44.93 years) with lesions in the maxillary sinus were examined and surgically operated. All patients underwent a comprehensive clinical examination aimed at a differential diagnosis of maxillary sinus pathology: cysts, polyps and neoplasms. All patients underwent endoscopic endonasal surgery: in 135 cases it was conducted via the inferior nasal meatus, in 40 patients — via the middle nasal meatus due to the large size of the cyst. Histology confirmed the established diagnosis during the clinical and instrumental examination. The postoperative period proceeded with no abnormalities. After 6 months, the patients underwent a control computed tomography of paranasal sinuses. In all cases, there was a complete cyst removal and restoration of sinus pneumatization. Thus, the differential diagnosis concerning cystic lesions of the maxillary sinus should be based on clinical manifestations and the results of X-ray techniques and follow-up of patients with scanty symptoms and signs. The optimal treatment method of maxillary sinus cysts is the endoscopic endonasal approach, followed by morphological examination. KEYWORDS: benign lesion, maxillary sinus cyst, cystic lesion, differential diagnosis, endoscopy, endoscopic endonasal approach.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 cm × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices and maxillary sinus floor triggered a significant reduction of maxillary sinus mucous membrane thickening. The presence of periodontal bone loss significantly increases maxillary sinus mucous membrane thickening.

Background/Aim. Mucocele of a paranasal sinus is a benign non-neoplastic condition characterized by cystic expansion and distension of the sinus cavity by retained mucoid secretions. Etiology is unknown. The purpose of this study was to estimate the efficiency of the endoscopic middle meatal antrostomy (MMA) as a treatment modality in patients with maxillary sinus mucoceles. Methods. This retrospective study involved 11 patients with maxillary sinus mucoceles/pyoceles treated endoscopically in the Clinic for Otorhinolaryngology of Military Medical Academy, Belgrade over a 3-year period (2005-2007). The presented symptoms and signs, radiological and pathohistological findings and surgical treatment were reviewed. Results. There were four females and seven males, age 22 to 65 years (mean 33 years). Two patients were with allergic rhinitis. All the patients complained of nasal obstruction, ten had facial pain, seven had nasal discharge, five had cheek pressure, and four had epiphora, and four had headaches. On endoscopic nasal examination, the medial wall of the maxillary sinus was bulging in ten patients. Purulent drainage was seen in eight patients, septal deviation in ten, and polyps were found in two of the patients. The MMA and marsupialization of the mucocele were performed in all the patients. On histopathological examination, the mucocele wall showed a lining composed of respiratory epithelium. Postoperative follow-up ranged between 8 and 44 months (in six patients, it ranged from 24 to 44 months). No patients required revision surgery. Conclusion. The MMA with mucocele marsupialization abolishes middle meatal obstruction and establishes better drainage and ventilation of the maxillary sinus and restitution of its mucosa.

Background: The purpose of the study was to analyze the efficacy of platelet-rich fibrin (PRF) as a single augmentation material for complicated cases of maxillary sinus floor elevation, resulting from membrane perforation or previous infections. Methods: Implant insertion in the posterior region of the maxilla was simultaneously performed with maxillary sinus floor augmentation. Schneiderian membrane elevation can be accompanied by extremely serious sinus membrane perforation, due to accidental tearing or intended incision for mucocele removal. PRFs were placed in the sinus cavity both for membrane sealing and sinus floor grafting. Radiological, histological and micro-CT analyses were performed. Implant survival was assessed every 6 months for 1 to 4 years, with a mean follow up of 1.8 years, after prosthetic loading. Radiological examinations were performed on CBCT at 9 and 12 and 36 months postoperatively and revealed improved degrees of radiopacity. Results: 19 implants were simultaneously placed in the course of nine maxillary sinus floor augmentation surgeries, with successful outcomes in terms of bone grafting and implant integration. New bone formation was evidenced 12 months postoperatively on radiological examination, micro-CT analysis, and histological analysis of a harvested bone segment from the augmented maxillary sinus. The mean gain in bone height of the sinus floor augmentation was 6.43 mm, with a maximum of 9 mm. The mean amount of vital bone obtained from histologic assessment was 52.30%, while bone volume/tissue volume ratio in micro-CT 3D had a mean of 50.32%. Conclusions: PRF may be considered as an alternative treatment for a single surgery of sinus augmentation with simultaneous implant placement, even in complicated cases with significant sinus membrane tearing.

Cholesterol granuloma (CG) is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. This article reports a case of CG in the maxillary sinus of a 22-year-old man, manifesting as a swelling on the right maxilla associated with pain and nasal obstruction. Computed tomography (CT) imaging showed complete opacification of the right maxillary sinus with cortical bone expansion and destruction. Incisional biopsy showed a solid mass filling the sinus and histological examination showed foreign body reaction to cholesterol crystals. The microscopic findings associated to tooth vitality, CT images and absence of a cavity during the surgical procedure were compatible with the diagnosis of CG of the maxillary sinus. Complete surgical excision of the mass under general anesthesia was suggested, but the patient did not return to conclude the treatment. CG must be included in differential diagnosis of diseases that cause opacification on the paranasal sinuses, especially sinusitis, and cystic and tumoral lesions.

Testo completoAbstract (sommario):
The purpose of this report was to analyse surgical methods for treatment of maxillary ameloblastoma and present three cases from our clinical practice in the postoperative period from 1,5 to 3,5 years. We present three patients with maxillary ameloblastoma with different etiology - two male patients and one female child. The location of ameloblastoma next to the maxillary sinus and nasal cavity indicates long-term and asymptomatic growth and comprises difficulties in clinical and X - ray examination. Ameloblastomas in posterior maxilla are very aggressive, more rapidly penetrate adjacent tissues and treatment must be radical. Subtotal resection of maxilla was carried out in all three patients, because this surgical method successfully eradicates tumor and minimizes the possibility for recurrences.

Abstract BACKGORUND. Sinus floor elevation, also known as sinus lift, is the surgical procedure meant to elevate the maxillary floor in order to increase the height of the alveolar bone. This will allow the oral surgeon specialist to insert the desired implants, the ground of dental reconstruction. As the procedure involves the maxillary sinus and its Schneiderian membrane the main concern is to have a healthy maxillary sinus prior to implantation and to the maxillary augmentation. OBJECTIVE. The aim of our study was to identify the patients with abnormal CT scan and refer them to an ENT evaluation, in order to identify and treat any sinusal pathology that can lead to a poor outcome of the sinus-lift intervention. MATERIAL AND METHODS. Our prospective study included 15 patients selected from a group of 79 adults, candidates for dental implantation with sinus augmentation. These patients had abnormal sinus CT scan in terms of mucosal hypertrophy, cysts or fungal material. Transnasal diameatic sinusoscopy was performed for all the patients, assessing the aspect of the sinus cavity and the mucosa. The following abnormal aspects were found in our group: 5 patients with cysts, 2 patients with fungus ball and 4 with mucosal hypertrophy. 4 patients had normal maxillary mucosa despite the CT scan appearance. RESULTS. All the patients with abnormal aspects at sinusoscopy (11 patients) were operated on before sinus lift procedure - antrostomy, cyst removal, fungus ball removal. 4 patients showed normal aspect of the sinus mucosa despite the CT scan donations, meaning a 26.66% error rate in appreciating the real changes of the maxillary mucosa on the CT scan. CONCLUSION. Endoscopic assessment of the maxillary sinus is mandatory in patients with changes of the CT scan. This allows a proper examination of the sinus mucosa and can predict the outcomes of the sinus lift procedures. It is mandatory to cure the inflammation or infection of the maxillary sinus prior to implant procedure in order to be able to increase the success rate, as it can lead to failures of the implant procedure.

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign neoplasm, with slow, localized, invasive, and asymptomatic growth. The involvement of the maxillary sinus by the neoplasm is rare, with its treatment controversial. The aim of this study was to describe the clinical, imaging, and therapeutic characteristics of a CEOT with maxillary sinus extension, as well as a literature review of therapeutic approaches and the prognoses obtained from cases of the same extension. In this case report, we report the case of a female patient, 49 years old, Caucasian, with mild asymmetry of the middle third of the face. Clinical and imaging examinations showed an intraosseous tumor in the posterior region of the left hemimaxillary, with imprecise limits and extension of 44×24×32 mm, compromising the alveolar process, maxillary posterior teeth, posterior hemipalatal region, left maxillary sinus, and orbital floor, associated with local expansion, tooth mobility, maxillary sinusopathy, and nasal obstruction. Calcifying epithelial odontogenic tumor diagnosis was obtained from incisional biopsy and histopathological examination. Surgical therapy of partial maxillectomy was performed from the Weber Ferguson Access with subsequent prosthetic rehabilitation. There were no postoperative complications. This case presented had satisfactory success with the therapy performed. The use of invasive therapies such as partial maxillectomies associated with transfacial approaches is an effective treatment for CEOT involving the maxillary sinus. Long-term follow-up is essential to avoid recurrences.

Maxillary sinus mucocele is a benign cyst formation that originates within the sinus and is lined by epithelium containing mucus. It’s a rare pathology characterized by a clinical polymorphism. This study reports the case of a giant left maxillary sinus mucocele in a 61-year-old female patient. Through clinical examination, vestibular deformation from tooth 23 to tooth 26 was determined, and also an exophthalmos. Facial CT scan showed a cystic mass of the left maxillary sinus with bone thinning. The treatment consisted in the excision of the mucocele pocket through Caldwell-Luc approach under general anesthesia.

Maxillary sinus floor augmentation is considered to play a critical role in dental implant treatment. Although many complications, such as maxillary sinusitis and infection, are well known, few reports are available on the risk of surgical ciliated cyst following the procedure. Here, we report a case of surgical ciliated cyst following maxillary sinus floor augmentation. A 55-year-old Japanese woman was referred to our hospital because of alveolar bone atrophy in the bilateral maxilla. We performed bilateral maxillary sinus floor augmentation by the lateral window technique without covering the window. The Schneiderian membrane did not perforate during the operation. She returned to our hospital after 9 years due to swelling of the left buccal region. Computerized tomography revealed a well-defined radiolucent area with radiodense border intraosseously localized in the left maxilla. We performed enucleation of the cyst with the patient under general anesthesia. Histological examination of the specimen showed a surgical ciliated cyst. In conclusion, the course of this patient has 2 important implications. First, the sinus membrane entrapped in the grafted bone without visible perforation and or tearing can develop into a surgical ciliated cyst. Second, there is a possibility that covering the lateral window tightly might prevent the development of a surgical ciliated cyst.

Maxillary sinus floor elevation using autologous or alloplastic bone grafting is often performed for implant treatment of maxillary molars; however, issues related to the donor site and complications such as infection have been reported. We performed maxillary sinus floor elevation using poly-L-lactic acid (PLLA) as a space-making material in patients with an insufficient bone mass (<3 mm) for simultaneous implantation between the alveolar crest and floor of the maxillary sinus and evaluated the newly formed bone. Conventional antrostomy of the maxillary sinus from the lateral wall was performed, and PLLA was placed on the floor of the maxillary sinus after elevating the sinus membrane. Six months after surgery, the bone mass and density were measured using quantitative computed tomography, and histological evaluation was performed. No complications were recorded. Radiological findings showed a bone-like radiopaque appearance, and histological examination revealed new bone formation in all patients. In cases with insufficient bone mass prior to simultaneous implant placement, this method of maxillary sinus augmentation allows for sufficient bone augmentation without bone grafting.

Testo completoAbstract (sommario):
Introduction: We described a rare clinical case of osteoma associated with homolateral radicular cyst of the maxillary sinus. Observation: Imaging showed two different lesions in the right maxillary sinus. We performed a combined surgical approach to completely remove the lesions and used a plasma rich in growth factors membrane to repair dental roots. No relapse after a 2 years follow-up was observed. Commentaries: The simultaneous presence of two large lesions, a 23,7 mm osteoma and a 33,7 mm radicular cyst in the same maxillary sinus, has been rarely described in the literature. Although nasal endoscopy and imaging are mandatory to assess the diagnosis, the definitive diagnosis was obtained after histopathologic examination. A combined surgical approach allowed a complete removal of both lesions, ensuring, at same time, an optimal surgical field. Plasma rich in growth factors membrane due to its cohesive properties was particularly useful in improving bone neoformation and periodontal regeneration. Conclusion: Diagnostic assessment of maxillary lesions requires nasal endoscopy, imaging and histopathological examination. If these lesions are symptomatic, they should be completely removed and minimally invasive surgery is indicated. Plasma rich in growth factors membrane ensures a good postoperative recovery.

We report the case of a 38-year old male patient with sinusitis caused by an infected follicular cyst due to an ectopic impacted third molar in the right maxillary sinus. A 10-day antibiotherapy regimen was administered; subsequently, the cyst and the third molar were removed achieving complete recovery. Fibrous dysplasia was diagnosed at follow-up examination (occupation of the maxillary sinus by bone tissue was observed in a radiographic examination) and confirmed by biopsy. In cases of odontogenic sinusitis, thorough examination is crucial, as evidenced by the case reported in this study. A Literature review was performed in order to identify the diagnostic methods currently available and the clinical features, complications and treatment for both, odontogenic maxillary sinusitis and fibrous dysplasia.

Abstract BACKGROUND. Chronic maxillary sinusitis is a frequently encountered pathology, resistant to treatment, which can cause significant economic losses. Considering these aspects, it is necessary to develop new methods of treatment. OBJECTIVE. The purpose of this study was to assess the therapeutic efficacy of the “Cahul” ozonated mineral water in the treatment of experimentally induced chronic rhinosinusitis and its action on the mucosa of the maxillary sinus. MATERIAL AND METHODS. The experimental study was conducted on a group of 14 chinchilla rabbits, aged between 8 and 12 months, weighing 2.5-3.0 kg, kept in vivarium conditions. In the first stage of the study, chronic rhinosinusitis was induced. 3 months after, maxillary antrostomy in the medial wall was performed on all animals included in the study; the intervention was performed under general anesthesia. The rabbits were divided into two groups. The rabbits enrolled in the study group underwent daily inhalations and maxillary sinus lavage with the “Cahul” ozonated mineral water. In the control group, inhalations and lavage were performed with 0.9% NaCl solution. Efficacy of the treatment was assessed observing the clinical character of the pathology. On days 2, 5 and 9 of the experiment, endoscopic and histological examinations were performed. RESULTS. On the ninth day of treatment, if in the study group the appearance of the sinus mucosa was almost normal, in the control group, the histological examination revealed: epithelial hyperplasia, cylindrical cell hyperplasia, thickening of the basement membrane and lymphocyte infiltration. Mucosal fragments harvested after 5 days revealed submucosal fibrosis, leukocyte infiltration in the control group being more pronounced than in the study group. CONCLUSION. Maxillary sinus lavage with the “Cahul” ozonated mineral water improves mucociliary clearance and stimulates regeneration of affected cells.

Testo completoAbstract (sommario):
Patients presented acute recurrences from Otorhinolaryngology treatments with unilateral symptoms compatible with maxillary sinusitis with a dental origin (MSDO). Cone beam computed tomography (CBCT) showed sinus extensive membrane thickening that was not visible at periapical exam associated to the maxillary molar infection in both cases. Respiratory structures assessment was possible using a 6-inches field of view CBCT. Non-surgical endodontic treatment (case 1) performed and retreatment (case 2) showed a fast symptoms relief. Recall examination after 15 days revealed healthy soft tissues with normal periodontal probing and no dental mobility. In addition, 15-day CBCTs revealed initial maxillary sinus membrane recovery after the endodontic approaches in the reported cases. No additional medical intervention nor antibiotics administration were necessary in these MSDO cases management. Long-term follow-up in such cases is advisable to exclude other potential dental or respiratory issues. Diagnose and follow-up using CBCT presented significant sinus membrane thick reduction with no symptom’s recurrence after the endodontic treatment.

Introduction. Maxillary sinusistis of odontogenic origin is a wellknown condition that occurs due to close relationship of the maxillary posterior teeth to the maxillary sinus. We presented two patients with symptoms and signs of chronic inflammation of the maxillary sinus of odontogenic origin. Case report. In both patients, after clinical examination, microbiological testing, skin prick tests to inhalant allergens, and endoscopy of the nasal cavity, we performed the cone beam computed tomography (CBCT) of paranasal sinuses, which showed thickening of the mucosal lining of the maxillary sinus. The mucosal oedema resulted in obstruction of the osteomeatal complex in both patients. The presence of a foreign body in the right alveolar recess in the first case and in the left osteomeatal complex in the second case were noticed. The both foreign bodies had densities similar to bone. The alveolar recesses in both cases were below the level of the nasal cavity floor. The patients were treated by endoscopic approach, a combination of lower and middle meatal antrostomy. The thickened mucous membrane was removed in the region of the osteomeatal complex, and then the foreign bodies were removed in both cases. Histopathological analysis proved that both foreign bodies were tooth roots. Conclusion. This case report show how be able to successfully surgically remove foreign bodies from the maxillary sinuses using endoscopic approach, a combination of both, lower and middle meatal antrostomy.

Antroliths are depositions composed of minerals, such as calcium phosphate, located around a foreign body into the sinuses; the maxillary sinus is most affected by antroliths, followed by the frontal sinus. The aim of this study was to report the case of the patient JVS, a 63-year-old male with no health disorders who was referred to the oral and maxillofacial surgery department of a reference hospital in Fortaleza, CE, Brazil, as a victim of a motorcycle accident. On physical examination, it was found that the patient exhibited fracture of the left maxillary and zygomatic bones. Upon examination by computed tomography imaging, besides the fracture lines, a hyperdense area of well-defined limits in the left maxillary sinus was observed. In surgical treatment, after fixation of facial fractures, a Caldwell-Luc access without lower meatal antrostomy was performed for foreign body removal and sinusectomy with restoration of sinus drainage. The foreign body was sent for histopathological study, which suggested the presence of an exogenous antrolith of the left maxillary sinus. Thus, it can be concluded that a careful analysis of imaging tests may show unusual changes found in the antral cavity, even without the occurrence of any clinical symptoms.

<p class="abstract">Cavernous haemangioma of the nose and paranasal sinuses is a rare lesion which often misdiagnosed preoperatively. It is slow growing and locally destructive due to pressure effect thus simulating the features of a malignant lesion. In this case we presented a 64-year-old gentleman whom presented with bleeding from right alveolar ridge. On examination revealed a friable mass of 2×2 cm which bled on contact mimicking malignant lesion. CT scan revealed a heterogenously enhancing soft tissue lesion with surrounding bone remodelling which made it difficult to rule out malignancy. The tissue punch biopsy suggestive of inflammatory myofibroblastic tumour, however unable to rule out low grade malignancy. With the dilemma of making an accurate preoperative diagnosis, we proceeded with right total maxillectomy as to provide a total resection of the tumour. Postoperative histopathological examination confirmed to be cavernous haemangioma. This camouflaged presentation of cavernous haemangioma was a challenge in the decision making to provide the best curative treatment. Cavernous haemangioma of maxillary sinus is a complex entity, thus diagnosing this lesion is in grey area for the surgeons. A high index of suspicion combined with the radiological finding is crucial in deciding the treatment option in such camouflaged presentations. An analytical and suspicious mind combined with histopathological and radiological examination is pertinent for confirmation of the diagnosis.</p>

Introduction. Mucormycosis of paranasal sinuses is a rare life-threatening opportunistic fungal disease that requires urgent treatment. The commonly involved are the immunosuppressed and immunocompetent patients. Patients are presented with facial or orbital cellulitis, necrotic palate, paresthesia of facial or trigeminal nerves and loss of vision, signs of meningitis. Radiological examinations are not sensitive in the early stages of infection. Definitive diagnosis is established by biopsy and histological examination of the necrotic tissue. Case outline. In August 2017, a 52-year-old female diabetic was admitted to the Clinic for Maxillofacial surgery due to the swelling and pain in the right side of the face, headache, fever, restriction of ocular movements, purulent rhinorrhea lasting for one week. Computed tomography examination showed spreading cellulitis of the right side of the face, total right maxillary end ethmoid sinus heterogeneous occupation and osteitis of the maxillary walls. Radical surgical debridement was performed. Histopathology and microbial tests were consistent with the finding of invasive mucormycosis. Liposomal amphotericin B 5mg/kg per day for four weeks was administered and patient?s glucose levels were controlled with injectable insulin and local status significantly improved. Patient was reoperated later due to the defect of the right maxilla. Conclusion. Early diagnosis and multidisciplinary approach including microbiology, pathology, radiology, surgery, hematology, infectious disease, intensive care and pharmacology is essential. Treatment of mucormycosis of paranasal sinuses requires prompt and aggressive treatment with antifungal agents, surgical debridement and control of predisposing factors.

Nowadays, the share of odontogenic maxillary sinusitis according to various authors can reach 40% among all sinusitis. The literature review of the diagnostic and treatment features of odontogenic maxillary sinusitis is done. The use of modern methods of radiation examination allows us to identify the cause of sinusitis and reveal its odontogenic nature. The main thing in the treatment of odontogenic sinusitis is the elimination of the stomatogenic cause of the disease. There are several different types of surgical treatment of maxillary sinus disease: Caldwell–Luke operation, endoscopic transnasal approach with access through the lower and/or middle nasal passage. Our clinical experience of treatment of 36 patients with odontogenic maxillary sinusitis at the ENT department. Odontogenic maxillary sinusitis does not have specific symptoms. There are no recommendations how to choose any approach according to pathology, anatomy, additional diseases etc.

Background Conflicting data exist about the presence of bacteria in healthy maxillary sinus cavities. This study was designed to determine the bacterial flora and to quantify the level of bacterial presence in healthy maxillary sinus cavities. Method Subjects included 34 patients undergoing Lefort I osteotomy for orthognathic surgery. All patients were preoperatively evaluated by a questionnaire and a complete physical examination including sinus endoscopy. Our exclusion criteria were presence of sinonasal symptoms, asthma, antibiotic treatment in the past 3 months, treatment with local steroids, previous sinonasal surgery, traumatic surgery, and an abnormal CT scan or sinus endoscopy. Washes were obtained from maxillary sinuses before surgery through an antral puncture. The sinus was irrigated with sterile saline followed by aspiration with a syringe attached to the trocar. Basic sterility rules were rigorously applied. Specimens were transported to the laboratory in an air-free syringe. Time between collection of materials and inoculation of the specimen did not exceed 15 minutes. Specimens were inoculated for aerobic and anaerobic organisms. Results After applying the selection criteria, 14 patients (28 sinuses) remained. Eight (57.1%) were men with a mean age of 22.7 years; 82.14% of the specimens were sterile. Bacterial organisms were recovered in only four patients with two different coagulase-negative staphylococci in the same patient: one in each sinus with 200 UFC/mL in the left sinus and 10 UFC/mL in the right sinus, one Citrobacter fundii (70 UFC/mL) and two polymorphic floras. Conclusion This descriptive study shows the large predominance of sterile maxillary sinus cavities in asymptomatic adults with endoscopically normal mucosa.

Testo completoAbstract (sommario):
The prevalence of mycotic infections of the paranasal sinuses is constantly increasing worldwide. Pathogens can enter the sinuses through the respiratory tract that leads to the colonization of microorganisms in both the lungs and paranasal sinuses as part of the normal microflora. The presence of filamentous fungi in the maxillary sinus may result from endodontic treatment of molars directly adjacent to the sinus, increasing the risk of fungal foci development. Fungal paranasal sinusitis manifests in invasive or non-invasive forms. While mycological culture remains the traditional gold standard for mycosis diagnosis, its sensitivity is reportedly low. Paranasal sinus cysts comprise 4-8% of general ENT pathologies and approximately 4-16% of chronic paranasal sinus diseases, with a predominant presence in the maxillary sinus. Factors that contribute to the development of sinusitis and create favorable conditions for fungal spore adhesion and growth include impaired ventilation and transport function of the sinus mucosa, inadequate use of broad-spectrum antibacterial drugs and steroid therapy, as well as household factors. Recently, there has been an increase in the number of cases of multiple small cysts in maxillary sinuses. Clinical manifestations range from asymptomatic incidental findings to varying degrees of discomfort and/or pain localized in the maxillary sinus area. The aim of this study is to identify the involvement of a fungal agent and to develop a set of therapeutic and prophylactic measures for polymicrocystic changes in the mucous membrane of the maxillary sinuses. The study enrolled 37 patients aged 18 to 65 years. Atypical cystic content was collected and cultured in Sabouraud's nutrient broth and Amies transport medium at 35-37°C for 5-7 days, with final measurements on day 21. Treatment involved a 14-day regimen of itraconazole (100 mg once daily) alongside topical miramistin (0.01% solution, 2 ml) sinus injections. The findings obtained demonstrate the following: positive fungal growth was observed in 26 cases (70.3%), predominantly Penicillium (48.6%) and Aspergillus (21.6%). Absence of growth was noted in 11 cases (29.7%). Follow-up examinations in 6 months and in a year revealed no crusts in the nasal cavity, moderate mucous discharge in the sinuses, and no polymicrocystic changes. Conclusion. The analysis has demonstrated the involvement of fungal flora in the development and recurrence of cystic changes in the maxillary sinus mucosa, advocating for mycological examination alongside bacteriological analysis. Itraconazole for systemic therapy and miramistin for topical therapy demonstrate efficacy in treatment and recurrence prevention.

The study incorporated treatment for 75 patients experiencing chronic purulent maxillitis exacerbation, employing the use of phytopreparations. After comprehensive examination, all patients were prescribed antibiotic therapy and decongestants, and subsequently underwent a maxillary sinus puncture. Patients in the first primary group underwent thrice-daily sinus cavity washes with a medicinal sage infusion. In contrast, the second primary group was treated with a hypericum perforatum infusion. For the comparison group, a 0.02% furacilin solution was utilized as an antiseptic for the puncture and wash of the maxillary sinus. The findings substantiate the advisability of prescribing the examined drugs to patients enduring an exacerbation of chronic purulent maxillitis.

We present a case of a 46-year-old woman admitted to the emergency department for acute swelling and erythema of the right eyelid for 3 days. Ophthalmological examination was notable for 10/10, P2 best visual acuity, and inflammatory periorbital edema, without exophthalmia nor extraocular motility disturbance. Intraocular pressure was 14 mmHg and fundoscopic examination was not notable for any abnormality. Preseptal cellulitis diagnosis was made, and oral antibiotherapy was immediately started; after 72 hours, the patient did not improve and started complaining of pain on ocular movements. Brain and orbit MRI scan revealed right retroseptal cellulitis associated with homolateral pansinusitis. Intravenous antibiotherapy with oral corticosteroid was started simultaneously leading to full remission but with steroid dependency; 5 days after finishing prednisone, orbital cellulitis symptoms reappeared. The same treatment protocol was given but with corticosteroid tapering over weeks. Nevertheless, steroid dependency persisted. Except for the inflammatory syndrome, complete biological examinations did not disclose any abnormalities. The patient underwent maxillary sinus and fat orbital biopsy; however, histopathological examination was not contributory. Persistence of steroid dependency, chronic atypical rhinosinusitis, normal paraclinical investigations, and age of patient let us suspect lymphoma origin hidden by chronic corticosteroid. We carried out for the second time a maxillary sinus biopsy after stopping steroids, which disclosed primitive non-Hodgkin lymphoma of the maxillary sinus. The aim of this observation is firstly to evoke though it is exceptional the diagnosis of maxillary lymphoma in case of atypical orbital cellulitis and secondly to incite clinicians to be more vigilant in prescribing corticosteroid even if there is an emergency character of orbital cellulitis.

Testo completoAbstract (sommario):
In 1863, the term “odontoma” was introduced by Paul Broca which he described as a tumor formed by overgrowth of transitory or complete dental tissue. The World Health Organization classified them under mixed benign odontogenic tumors because of their origin from epithelial and mesenchymal cells, exhibiting different structures of dental tissue (enamel, dentin, cementum and pulp).1 There are two distinct types: compound and complex. Compound odontoma is composed of all odontogenic tissue in an orderly fashion resulting in many teeth-like structures but with no morphological resemblance to normal teeth, whereas a complex odontoma appears as an irregular mass with no similarity even to rudimentary teeth.2,3,4
The pathogenesis of odontomas has not been completely established, although the most accepted etiology is related to trauma, infection, growth pressure, and genetic mutations in one or more genes that cause disturbances in the mechanism controlling tooth development.1,5
Patients with compound odontoma are often asymptomatic. It is usually detected on routine radiography upon examination of an unerrupted tooth.6 Odontomas can occur anywhere in the jaws and are usually found associated with or within the alveolar process.7 However, the presence of an odontoma in the maxillary sinus is very rare.
We present a female patient with a compound odontoma in the maxillary sinus, initially managed as nasal vestibulitis with maxillary sinusitis.
CASE REPORT
A 63-year-old woman from Cavite City, Philippines consulted in our institution due to perception of foul odor. Six weeks prior to admission, she experienced right alar pain, facial fullness and swelling with associated undocumented fever. She consulted an ENT specialist and was diagnosed with nasal vestibulitis with maxillary sinusitis. She was given cefixime 200mg, one tablet twice a day and Metronidazole 500mg, one tablet every six hours for seven days.
Five weeks prior to admission, despite resolution of the nasal and maxillary swelling and pain, she started to perceive a foul odor. There was no associated nasal congestion and nasal discharge, fever, no nasal itchiness nor frequent sneezing. Her physician requested an orthopantomogram hat revealed a suspicious mass and haziness in the right maxillary sinus and an impacted tooth in the left maxillary sinus. (Figure 1) She was advised surgery but opted for a second opinion.
2 weeks prior to admission, still with perception of foul odor, she consulted another ENT specialist and was given co-amoxiclav 625mg, one tablet every eight hours. A CT scan of the paranasal sinuses revealed mucoperiosteal thickening and calcific density within the opacified right maxillary sinus. (Figure 2 A, B) The patient was advised surgery.
The patient had pulmonary tuberculosis in 1983 but was treated for six months. She does not recall having any un-erupted teeth and claimed that her previous dental extractions were unremarkable. She had a family history of bronchial asthma and colon cancer. She did not drink alcoholic beverages but she previously smoked for 1 pack-year.
Anterior rhinoscopy revealed scant clear mucoid discharge in both nasal cavities, noncongested and nonhyperemic turbinates, and no intranasal mass. She was edentulous, with no facial mass or swelling. The rest of the examination was unremarkable.
With an assessment of a right maxillary mass (odontogenic tumor versus foreign body) with right maxillary sinusitis, and an impacted tooth in the left maxilla she underwent a Caldwell-Luc procedure. Antrotomy was performed through the canine fossa via a gingivolabial incision overlying the anterior maxillary wall. Thick clear mucous was seen oozing out and eventually drained and suctioned out. (Figure 3) A 2 cm x 2 cm x 2.1 cm ovoid, whitish to tan colored hard mass partially covered by black fragments was carefully extracted. (Figure 4) Irrigation of the maxillary sinus was performed using normal saline solution and the natural maxillary ostium was widened. The incision was closed with interrupted mattress sutures using chromic 3.0 and the mass was submitted for histopathological analysis.
Microscopic sections revealed misshapen teeth or denticles with a coordinated pattern of calcification such as enamel, dentin and cementum. (Figure 5 A - C) The final histopathologic report was a compound odontoma of the right maxillary sinus.
The postoperative follow-up was satisfactory. Our patient developed no oro-antral fistula and showed no signs of maxillary sinusitis and the perception of foul odor resolved.
DISCUSSION
Odontoma is a generally asymptomatic, slowly progressing tumor that may pass unnoticed. It is usually detected by routine radiograph. This may be associated with un-erupted tooth, mainly the mandibular third molar, followed by the upper canine and upper central incisor. The prevalence of odontoma associated with impacted canine is 1.5 %.8 The maxillary sinus is a frequent site for pathologies of odontogenic origin because of its close anatomical relationship with teeth and periodontal tissues. This makes a frequent but not a common site for inflammatory diseases as well as neoplastic lesions.6 The patient initially presented with right alar pain and right facial swelling. She did not recall having an un-erupted tooth and claimed that her previous dental extractions were unremarkable. After treatment, the pain and swelling resolved but she started to perceive a malodorous smell. Commonly, clinicians arrive at the diagnosis of sinusitis when failure of its resolution despite antibiotic treatment prompts warning bells that warrant further radiographic investigation. The radiographic appearance of odontoma is almost always diagnostic3 as in the presented case. Panoramic and periapical images usually show well-defined borders of a similar density to calcified dental tissue, having a ground-glass appearance, and a radiopaque mass occupying the affected maxillary sinus.9 This was evident in the patient's panoramic radiograph.
Additional radiographic evaluation with computed tomography was necessary to determine the extension and features of the lesion because periapical and panoramic images do not provide complete visualization of the maxillofacial complex. CT scans serve as a guide not only for evaluation of the lesion itself, but also for localization of associated pathology and proper treatment planning.10 In this case, the computed tomography scan of the paranasal sinuses revealed mucoperiosteal thickening and calcific density within the opacified right maxillary sinus, suggesting odontogenic origin with concomitant maxillary sinusitis.
Due to its asymptomatic course, it can be surmised that the patient might have had the asymptomatic compound odontoma for a long time. The mass in her maxillary sinus was seen freely floating in her CT scan. It may be hypothesized that obstruction by the odontoma could have altered the ventilation and drainage of the maxillary sinus, causing the symptoms of the patient. Cabov, et al. reported that odontomas in the maxillary sinus may also cause pain, facial asymmetry and chronic congestion of the sinus.11
Management for this case was surgical removal of the mass with drainage of trapped mucus as well as medical treatment of the maxillary sinus infection. The Caldwell-Luc procedure was the favored approach to this case because it offered easy access to the mass that could not be extracted trans-nasally because of its size and solid nature. Restoring the drainage of the maxillary sinus was also essential and this was done by widening the natural maxillary sinus ostium.
The histological characteristics of the mass extracted from the patient consisted of denticles with a coordinated pattern of calcification such as enamel, dentin and cementum, compatible with a compound odontoma.
The rarity of odontomas makes them easy to miss should a radiographic examination not have been done. Despite their being usually asymptomatic, our patient had chronic perception of foul odor that was bothersome and frustrating. A clinician relying on medical history and physical examination alone could not have arrived at the correct diagnosis. In this case, it was shown that radiographic imaging was very crucial in catching a hidden and rare tumor.

Testo completoAbstract (sommario):
Odontogenic maxillary sinusitis is damage to the mucosa of the maxillary sinus caused by the spread of inflammation from periapical dental processes in the immediate proximity or prominent in the maxillary sinus. Another ethiology can be trauma or dental tumors with or without infection. Failure to identify the etiological dental factor usually causes severe complications. An early history and a thorough clinical examination, together with a radiological evaluation, are key factors in establishing a correct final diagnosis. The multidisciplinary approach between dentists, ophthalmologists, otorhinolaryngologists, neurologists and other specialists is necessary to avoid further complications, which sometimes put the patient’s life at risk. A medical management and an early diagnosis corresponding to the dental pathology, remain critical in the treatment of maxillary sinusitis of dental origin and the prevention of severe complications.

Abstract Introduction. Chronic periodontal diseases and dental caries are the primary reasons for tooth loss in adults, which is further increased in people with diabetes. In most cases of bone loss, the treatment of partial edentulous patients with implant supported restorations impose additional surgical procedures, like sinus lift elevation and bone augmentation, which can complicate the healing process. Case report. This case report presents a type 2 diabetes female patient with several oral health problems, like periodontal disease, poor decay control, bad oral hygiene, a severe maxillary atrophy and the presence of a large maxillary periapical cyst. After a careful examination, based on clinical and radiographic findings, a comprehensive treatment plan was established. The sequential treatment plan consists in extraction, surgical removal of periapical cyst, bilateral external sinus lift procedures and bone augmentation. The surgical protocol was adapted to the particular health conditions of this type 2 diabetes patient. Conclusion. Sinus elevation and bone augmentation are predictable procedures often required when restoring the posterior maxilla with dental implants. In case of diabetes patients with bone resorption and defects due to periapical cyst, if the correct protocol is followed, no post-surgical complications and good result in bone augmentation can be attaint.

Background In patients with chronically diseased maxillary sinuses, poor mucociliary clearance may result from long-standing inflammation or scarring from previous surgery. This subset of patients often has persistent sinus disease despite medical therapy and adequate antrostomy. Endoscopic maxillary mega-antrostomy (EMMA) is a mucosal sparing technique that facilitates mucus clearance and sinus irrigation in terminally dysfunctional maxillary sinuses. EMMA involves extending the antrostomy through the posterior half of the inferior turbinate down to the floor of the nose, creating a significantly enlarged antrostomy. This study describes our results of EMMA in recalcitrant maxillary sinusitis. Methods A retrospective review was performed of patients who underwent EMMA for recalcitrant maxillary sinusitis between July 2005 and September 2007. We studied diagnoses, comorbid factors, clinical efficacy, revision rate, and complications. Results Twenty-eight patients (average age, 48 years) underwent 42 EMMAs for recalcitrant maxillary sinusitis. Average follow-up was 11 months. All patients had previous maxillary sinus surgery (mean = 2.3). Relevant comorbid factors included prior Caldwell-Luc or maxillofacial surgery (16/42), cystic fibrosis (11/42), asthma (11/42), and IgG deficiency (3/42). The most common symptoms reported were facial pain/pressure and purulent rhinorrhea. At the time of the most recent postoperative examination, 74% of patients reported complete resolution of symptoms while 26% reported partial symptomatic improvement. There were no complications and the revision rate was 0%. Conclusion Maxillary sinuses that appear to be terminally diseased may be rehabilitated surgically without the need for surgical stripping. EMMA is an effective and safe treatment option for the management of recalcitrant maxillary sinus disease.

Disorders affecting the equine maxillary cheek teeth and paranasal sinuses are relatively common, but limited objective information is available on the dimensions and relationships of these structures in horses of different ages. The aims of this study were to assess age-related changes in the positioning and anatomical relationships of the individual maxillary cheek teeth with the infraorbital canal and maxillary septum and the volumes of the individual sinus compartments. CT and gross examination were performed on 60 normal equine cadaver heads that were aged by their dentition. The intrasinus position of cheek teeth, length of reserve crowns, relationship to the infraorbital canal and measurements of rostral drift and sinus compartment volumes were assessed from CT images. The findings included that Triadan 10 alveoli lay fully or partially in the rostral maxillary sinus (RMS) in 60% of cases. The infraorbital canal lay directly on the medial aspect of the alveolar apex in younger horses. The Triadan 11’sclinical crowns and apices drifted a mean of 2.48 and 2.83 cm more rostral to the orbit, respectively, in the >15 years old vs the <6 years old age group. The mean volumes of sinus compartments ranged from 175 cm3for the caudal maxillary sinus (CMS) to 4 cm3for the ethmoidal sinus (ES). This information should be of value in the diagnosis and treatment of equine dental and sinus disorders and as reference values for further studies.

Maxillary sinus lift surgery is applied to compensate for the reduced vertical height in the posterior maxilla to facilitate placing a dental implant of a suitable length. Pathological conditions may be accidentally discovered, which necessitate careful assessment and management to prevent the infection of the maxillofacial complex and eventually bone grafting and dental implant failure. This case report describes an approach for the management of Schneiderian membrane perforation associated with the removal of an antral pseudocyst for successful dental implant therapy. A 70-year-old healthy Caucasian male presented for implant therapy to replace a non-restorable maxillary molar. Initial examination revealed the need for a sinus lift procedure to prepare the site for implant placement. A 3D CBCT evaluation before surgery revealed an incidental finding of a pathological lesion at the surgical site. The histological analysis of a biopsy specimen retrieved during implant site preparation showed findings consistent with antral pseudocyst. The resulting perforation of the sinus membrane was treated, and an adequate period of healing was given. A thickened sinus membrane was detected upon surgical exposure for implant placement. The novel technique illustrated could result in a fibrotic repaired sinus membrane and help shorten the time required for dental implant treatment.

Maxillary sinus retention cysts (MRCs) are typically asymptomatic and require no treatment. An early 30s man presented with a decade-long history of severe left-sided chronic facial pain (CFP). Multiple prior treatments resulted in an edentulous patient with persistent pain. Imaging revealed a dome-shaped radiopaque change in the left maxillary sinus. History and clinical examination suggested persistent idiopathic facial pain, and doubts about the outcome of a surgical intervention were explained to the patient. Surgical removal of the MRC via lateral antrotomy led to complete symptom resolution of CFP. This case substantiates the importance of considering MRCs as a possible cause of CFP. It also emphasises the need for a systematic multidisciplinary approach in cases of unexplained CFP.

Testo completoAbstract (sommario):
Disease of the paranasal sinuses is a common and costly condition. Evaluation of the efficacy of either medical or surgical methods of treatment is limited by the lack of quantitative methods to characterize sinus ventilation, which may be an important determinant of the baseline physiological state of the sinuses. Xenon-enhanced computed tomography (Xe-ct) measurement of sinus ventilation provides a noninvasive method of quantifying maxillary sinus ventilation using the nonradioactive, radiodense gas Xe as a tracer. Study subjects breathed a mixture of Xe gas and oxygen through a close-fitting nasal mask during serial ct imaging of a single radiographic plane through the maxillary sinuses — a generally well-tolerated protocol. Analysis of the sinus density–time curves allowed calculation of first-order exponential time constants from which specific ventilation rates could be determined for individual sinuses. Previously developed data analysis techniques were used to assess the statistical significance of the data and determine confidence intervals, allowing examination of the effects of noise in the data, and to demonstrate areas for further study protocol refinement. We conclude that Xe-ct measurement of sinus ventilation is a potentially valuable noninvasive technique for the diagnostic imaging of the human maxillary sinus.

Subject. Chronic odontogenic maxillary sinusitis is an inflammatory disease of the mucous membrane of the maxillary sinus caused by an odontogenic infection. According to foreign sources, this disease occurs in 14-20% of the world's population. Sinusitis of odontogenic etiology account for up to 40% of all inflammatory diseases of the maxillary sinus. Biofilm, the root cause of apical periodontitis and odontogenic sinusitis, is resistant to the isolated effects of most medications. The combination of mechanical removal and irrigation in most cases leads to a sufficient reduction in microbial load. Several studies have concluded that none of the currently used root canal treatment methods and endodontic instruments can completely clean root canals, especially root canals with "irregular anatomy". When preparing the upper molars with rotary instruments, 43% ± 29% and 33% ± 19% of the walls of the mesiobuccal and distobuccal channels, respectively, remained intact.
Methodology. The article presents a case of treatment of a patient with a periapical abscess with a fistula communicating with the maxillary sinus, as well as concomitant maxillary sinusitis. Positive dynamics in the healing of the periradicular process was achieved by increasing the apical diameter of the preparation.
Result. Healing of the periradicular process, as well as inflammatory phenomena in the maxillary sinus at the time of examination after 10 months from the start of treatment.
Conclusions. Thus, an increase in the apical diameter to sizes "unusual" for a dentist (45.02, 50.02 according to ISO) not only contributes to the healing of the periradicular process, but also does not weaken the root of the tooth, since the true diameter of the apical zone is much larger than it seems at first glance.

ABSTRACTBackground: Most of fascial space infections of head and neck caused by odontogenic infections. The canine space becomes involved primarily as the result of infections from the maxillary canine tooth. The buccal space may become infected from extensions of infection from either the maxillary or mandibular teeth.Purpose: This case report discusses the management of canine fossa space abscess extending to buccal space.Case: A-45-years-old male patient came to the A.W. Sjahranie Hospital with complaints of swelling in his left face since two weeks ago. Physical examination showed swelling in the upper left jaw. CT scan’s view showed a radiolucent appearance of the canine fossa region. Panoramic radiograph pointed upper left canine (23) and first molar (26) as source of infection. Based on clinical and radiographic examinations, the patient was diagnosed with a canine fossa space abscess. Case Management: The treatment was given are intravenous antibiotics, multiple tooth extraction followed by intraoral drainage incision under general anesthesia.Conclusion: Extension of infection of the canine fossa space can lead to the buccal space and maxillary sinus at the same time due to multiple carious tooth. Keywords : Buccal space abscess, Canine fossa space abscess, Maxillary sinus, Odontogenic infection

The fungal ball is the most common clinical form of fungal etiology sinusitis. The main method of treatment of patients with this pathology is surgery. Achieving complete removal of the fungal body is important, especially in patients who will have planned dental implantation. Among the accesses to the maxillary sinus in cases of the fungal body of the sinus, the most common one is through the middle meatus, but it does not provide visual control of the anterior parts of the sinus during the intervention. The use of modified infraturbinal access provides better opportunities for examination of the anterior parts of the maxillary sinus. The purpose of the study is to increase the effectiveness of surgical treatment of patients with fungal bodies of the maxillary sinus by optimizing access during endoscopic endonasal intervention. Materials and methods. The data of 113 patients with fungal ball of maxillary sinuses who underwent sinusotomy in preparation for dental implantation were analyzed. Cone beam computed tomography of paranasal sinuses of patients were performed twice – before functional endoscopic sinus surgery and before subantral augmentation of the maxillary bone. Group 1 included 78 patients to whom the fungal balls were removed from the sinus through the middle nasal meatus, group 2 – 35 patients to whom, in cases when it was impossible to visually confirm the completeness of removal of the fungal ball from the anterior area of the sinus, an additional infraturbinal approach was performed in our modification. Results and discussion. According to tomography before rhinosurgery it was established that "blackout" of more than 60% of the sinus space is observed in 50.5% of patients with fungal bodies, with the vast majority of patients (88.1%) fungal bodies in the maxillary sinus are located in its lower parts and spread forward from the nasolacrimal canal level. During sinus rehabilitation, the need for additional infraturbinal access arose in 5 (14.3%) patients of the second group. As a result of its performance in all 5 operated patients polyposis-altered tissues were found in "blind zones" and in 2 (5.7%) – there were also remains of a fungal body. Residual fungal bodies in the maxillary sinus were detected in 3 (3.9% CI 95% – 0.01; 11.6) patients of the first group, and were not observed in the second group. All cases of residual fungal masses in the sinus were not accompanied by specific complaints. A revision of sinusitis with fungal masses removing was performed on 3 patients due to the appearance of residual fungal bodies by preformed antrostomy with local anesthesia. Conclusion. Anthrostomy using additional endoscopic infraturbinal access when removing the fungal body from the lower anterior maxillary sinus is the optimal combined access that allows maximum visualization of the maxillary sinus and avoid recurrence of the disease

Цель. Разработка предложений и рекомендаций, направленных на совершенствование хирургического лечения кист верхнечелюстного синуса.Материалы и методы. В основу научно-исследовательской работы вошло обследование 139 пациентов с кистозным поражением верхнечелюстных синусов. Все пациенты были подвержены хирургическому лечению. Исследование проводилось в различных группах: основной группе, группе сравнения и контрольной группе. Пациентам основной группы предложен усовершенствованный вариант гайморотомии через нижний носовой ход.Результаты. Оценка клинической эффективности основывалась на показателях состояния функционального слоя слизистой оболочки полости носа. Усовершенствованный способ хирургического лечения через нижний носовой ход обладает более высокой клинической эффективностью для санации максиллярного синуса с сохранением интактных структур остиомеатального комплекса, это позволило сократить время восстановления мукоцилиарного транспорта слизистой оболочки полости носа и всасывательной функции в раннем послеоперационном периоде.Заключение. Разница в качестве жизни между двумя группами составила 12 баллов, что говорит о более высоком качестве жизни пациентов основной группы после лечения по улучшенной технологии. Purpose. To develop proposals and recommendations aimed at improving the surgical treatment of maxillary sinus cysts.Materials and methods. The research work was based on examination of 139 patients with cystic lesions of the maxillary sinuses. All patients underwent surgical treatment. The study was conducted in different groups: the main group, the comparison group and the control group. Patients of the main group were offered an improved version of maxillary sinusectomy through the lower nasal passage.Results. Evaluation of clinical efficacy was based on indicators of the state of the functional layer of the nasal mucosa. An improved method of surgical treatment through the lower nasal passage has a higher clinical efficiency for the sanitation of the maxillary sinus while maintaining intact structures of the ostiomeatal complex, which made it possible to reduce the recovery time of the mucociliary transport of the nasal mucosa and absorption function in the early postoperative period.Conclusion. The difference in the quality of life between the two groups was 12 points, which means a higher lifestyle of patients in the main group after treatment with improved technology.

In the treatment of odontogenic maxillary sinusitis, the removal of causative teeth is actively used, although the tooth removal indications are not always clearly defined. Modern endodontic approaches and technologies, in most cases, help preserve the tooth in the oral cavity with the elimination of the chronic infection focus, thus restoring the integrity of the maxillary sinus.
Background. Improve the effectiveness in the treatment of odontogenic maxillary sinusitis while preserving the causative teeth.
Materials and methods. The study involved 50 patients aged 18 to 45 years. All patients had clinical signs of maxillary odontogenic sinusitis and signs of failed endodontic treatment of teeth with a dark, radiolucent focus in the apex region. Radiological parameters and quality of obturation was assessed using CBCT; the presence of symptoms of inflammation was assessed clinically during examination. The results were evaluated after 6, 12 and 24 months. The treatment effectiveness and the quality of obturation was assessed in accordance with the directives of the European Society of Endodontology.
Results. High-quality endodontic treatment resolved clinical signs of odontogenic sinusitis in all patients, restored the bone tissue of the alveolar process and restored the mucous membrane of the maxillary sinus after 12 months in 96% of cases. In 2 cases, additional microsinusotomy was required.
Conclusion. Improving the quality of endodontics in the first treatment or retreatment of the upper jaw teeth can significantly reduce the number of dental extractions in odontogenic maxillary sinusitis

Mesiodens is the most common type of supernumerary tooth, located between the maxillary central incisors. A young man was referred by his orthodontist for management of a supernumerary tooth located in quadrant I, superposed to the bottom of the right maxillary sinus, distally orientated with the crown in contact with the apex of the palatal root of the maxillary first molar. The tooth was found on a panoramic radiography before starting his orthodontic treatment. To remove it and in order to study, its relationship to the anatomical structures a cone-beam CT examination was performed. This revealed the presence of a mesiodens located on the right paramedian maxillary area. Pericoronal tissue submitted for histopathological examination showed an uninflamed dental follicle. Healing was uneventful. This case shows that mesiodens outside the arch, located in the posterior palate, may be not discovered in a panoramic radiograph.

BACKGROUND The paranasal sinuses (PNS) have various anatomical difference. Computed tomography (CT) is an excellent means of providing anatomical information of this region, disease extent, assisting endoscopic evaluation and guiding treatment. Functional endoscopic sinus surgery (FESS) has become an increasingly popular treatment for chronic sinus diseases. CT of the paranasal sinuses has become a roadmap for FESS. The present study focuses on the assessment of the efficacy, safety and benefits of functional endoscopic sinus surgery in cases of maxillary pathologies and also study the anatomical variations in maxillary sinus in computed tomography and its usefulness in planning and management of chronic sinonasal diseases. METHODS It was a prospective study and a total of 80 patients were included in this study from July 2019 to June 2020 in the Otolaryngology Department, KIMS, Karad. Standard surgical steps were applied in each case according to the extent of disease. All patients underwent standard post-operative care. All findings were recorded and studied. RESULTS Total number of patients were 80. Of which, 31 (38.75 %) patients were operated for ethmoidal polyp, 24 (30 %) for chronic rhinosinusitis, 10 (12.5 %) for antrochoanal polyp, 9 (11.25 %) for rhinosporidiosis and 6 (7.5 %) for inverted papilloma. Postoperative complications were periorbital echymoses (13 %), synechiae (2.5 %), epiphora (2.5 %), infection (2.5 %), hemorrhage (4 %). Complete relief of symptoms were noted in 81.67 % cases. CONCLUSIONS Successful outcome and patient satisfaction post treatment can be obtained by careful evaluation and patient selection by history, examination and most importantly, proper imaging of the sinuses.

AbstractIn the recent years, the development of stomatology with emphasis on dental implants procedures has led to an increase in the number of sinonasal complications. Sinonasal complications of dental disease and treatment are an important cause of sinus pathology, being responsible for 10-12% of all causes of chronic maxillary rhinosinusitis.The main etiological factors involved in odontogenic sinusitis are represented by dental fillings, tooth roots in traumatic extraction, dental implants displacement and parts of broken instruments. The diagnostic work-up includes evaluation of the symptoms, history of dental treatment, dental examination, CT scan and nasal endoscopy.The treatment is surgical and can be represented by transnasal endoscopic technique performed by the otorhinolaryngologist or a transoral technique performed by the maxillofacial surgeon when oro-antral fistulas are present. The endoscopic approach is preferred but has its limits when the tooth root is placed in the alveolar recess, or at the level of the anterior, medial and lateral wall of the maxillary sinus. Concurrent middle and inferior antrostomy provides a better view of the sinus and increases effectiveness of the surgical treatment with minimal physiological damage.

the entrance of a foreign body (FB) into the maxillary antrum is common in trauma patients where bullets or any other materials trapped in the maxillary sinus; however, iatrogenic cause by a dentist that results in FB entrapment in the maxillary antrum is rare. All these FBs can cause sinusitis. If not treated properly they will cause serious infection, which may spread to the other paranasal sinuses. A careful clinical examination and treatment plan will prevent further complications. In this review, we present a rare case of dental bur (DB) found in the left maxillary antrum. A review of literature revealed only a few cases published which describe a dental bur dislodged in the maxillary antrum.

Introduction: Maxillary sinus pneumatization and alveolar ridge resorption following the extraction of posterior teeth make the installation of dental implants in the maxillary posterior region challenging. The direct sinus lift procedure proved to be a viable treatment option for such conditions. Aim of the study: to evaluate the mineralized plasmatic matrix/xenograft mixture in sinus elevation surgery. Materials and Methods: Eighteen patients were selected and randomly allocated into two groups; study group received a mineralized plasmatic matrix/xenograft mixture, while the control group received xenograft alone following sinus lifting. Results: The early wound healing index score showed a non-significant difference between both groups. Also, bone height was evaluated at the 6-month follow-up period, and there was a non-statistically significant difference. Core biopsies were taken for histological examination by H&E from both groups, revealing the presence of a more mature bone matrix in relation to the test group. Conclusion: The addition of mineralized plasmatic matrix to xenograft can speed up bone formation, thus reducing treatment duration.

AbstractWe retrospectively analyzed the clinical characteristics and treatment outcomes of patients with maxillary sinus squamous cell carcinoma. The patients were 22 newly diagnosed cases of maxillary sinus squamous cell carcinoma who were treated at our institute between 2005 and 2016. There were 19 males and 3 females, ranging in age from 45 to 83 years (average age: 64.2 years). Our treatment protocol was as follows: All patients received chemoradiotherapy with weekly superselective intra-arterial administration of cisplatin (radiotherapy and concomitant intra-arterial cisplatin [RADPLAT]; 100–120 mg/body). Good responders at 30 to 40 Gy received additional radiotherapy (RADPLAT, ordinary chemoradiotherapy, or radiotherapy alone) until the total dose reached 72 Gy, whereas the other patients underwent radical surgery (partial maxillectomy, total maxillectomy, or extended total maxillectomy). The latter patients were given postoperative (chemo)radiotherapy up to a total dose of 72 Gy, when histopathological examination revealed insufficient resection or a positive surgical margin. The overall 5-year crude and disease-specific survival rates determined by the Kaplan–Meier method were 47.8 and 56.9%, respectively. The crude survival rate tended to be higher in T3 patients than in T4 patients (80.0 vs. 29.9%, p = 0.077). Seven patients died of the primary disease. The cause of death was distant metastasis in four patients, recurrence of the primary lesion in two patients, and cervical lymph node metastasis in one patient. These results suggest the importance of early detection and early treatment, and of the development of more effective treatment for advanced maxillary cancers, to further improve the survival rate.

Objective: To determine the impact of CBCT on diagnostic evaluation and treatment plan for the maxillary sinus in dental implant planning. Material and Methods: Diagnostic evaluation and treatment plan for the maxillary sinus were evaluated by eight specialists experienced in dental implant placement. Eight panoramic radiographs (PAN) and CBCT examinations were obtained from five adult patients with a specific clinical need for dental implants. Evaluation was performed first on PAN then, at least 2 weeks later, on CBCT. Residual alveolar ridge height, mucosal thickening, radiographic findings and treatment plan were recorded. The confidence level was evaluated for both diagnostic evaluation and treatment plan. The kappa statistic for intra-observer reproducibility and McNemar test were performed. Results: In the diagnostic evaluation, CBCT showed significant impact on the diagnosis of radiographic findings. Availability of CBCT significantly changed the treatment plan, for less invasive treatment, or no treatment need. Observers had significantly greater confidence when using CBCT than PAN, when indicating presence of mucosal thickening and radiographic findings in the maxillary sinus. In addition, CBCT increased confidence in the treatment plan. Conclusion: The present study suggests that CBCT has an impact on the diagnostic evaluation of radiographic findings in the maxillary sinus and on the decision to place implants, owing to misdiagnosis of pathology and planning of more invasive treatments when using PAN. Availability of CBCT also improves clinician confidence. Further studies at higher levels of diagnostic efficacy should be performed, to justify the use of CBCT, by evaluating the actual treatment performed and its outcome.

The aim of the study was to assess the effect of pathogenic microflora on the postoperative period of simultaneous surgical intervention in patients with chronic maxillary sinusitis and partial absence of teeth in the distal parts of the maxilla in 49 patients (25 to 65 years old), who were divided into 2 groups (I — with identified pathogenic microflora, II — with normal microflora). Simultaneous surgical intervention included endonasal endoscopic maxillofacial surgery in combination with subantral plastic surgery and/or dental implantation, if necessary, with correction of intra-nasal structures. According to the results of clinical, hardware and laboratory research methods, it was noted that the proposed algorithm of examination and simultaneous surgical intervention in combination with conservative therapy allows for such treatment in patients with pathological flora in the maxillary sinus.

Sinus tumors are arduous to diagnose due to often prolonging asymptomatic course until the infiltration of the adjacent structures occurs. Therefore, patients are diagnosed with advanced-stage disease, which negatively affects the treatment outcomes. A 60-year-old male was referred to our ward from an outpatient clinic. The patient presented with double vision, right-side lacrimation, and exophthalmos. He also reported significant weight loss: 15 kg in 2 months. Physical examination revealed achiness and edema of the right temporal area, and subconjunctival hemorrhage of the right eye, and surprisingly no anosmia, no nasal obstruction, and no head/neck lymphadenopathy were present. The histopathology examination identified diffuse large B-cell lymphoma (CD20+ CD3- p63- bcl-2+ CD23-/+ bcl-6+ CD 10- MUM1+ Tdt- CD38- cyclin D1- CD30- c-myc+). The patient was qualified for R-CHOP immunochemotherapy (rituximab, cyclophosphamide, and hydroxydaunorubicin hydrochloride), which was well tolerated. After 3 months of treatment, all of the symptoms reversed and a whole-body PET scan showed no abnormal metabolic activity.
