Abstract:

AbstractThis essay attempts to address the perennial question ‘Why Paranasal Sinuses?’. In doing so it highlights the flaws in many much-favoured but ill-founded theories concerning the role of these sinuses in humans. It is concluded that the question can only be fully answered through a greater understanding of differential growth changes within the craniofacial massif.

Abstract:

The size and configuration of the paranasal sinuses and mastoid air cell system, which are the biggest air spaces in the human body, are important when planning endoscopic sinus procedures. As a result, various investigations using CT, MRI, cadaveric exams, and histological studies have been done to determine the size and volume of the paranasal sinuses. In assessing the disorders of the paranasal sinuses, computed tomography has acquired widespread recognition. It has been widely used in the assessment of malignant disorders. CT allows for simultaneous visualisation of both bone and soft tissue components. Environmental variables and hereditary illnesses have an impact on the development of the paranasal sinuses. Age had an effect on the growth of both the paranasal sinuses and the mastoid air cell. The paranasal sinuses have a high correlation between their volumes, indicating that they are in proportion to one another. The architecture of the paranasal sinuses, their evolution, the many materials and methods used to research them, and the probable variations in their size and volume are all discussed in this article. Key words: Paranasal sinuses; Computed tomography; Volume.

Abstract:

AbstractMucoceles are benign, expansive, cystic tumors, affecting especially the adult, with development in the paranasal sinuses. Clinical symptoms are not specific. These are rare conditions that originate within the sinusal mucosa, favoured by the obstruction of the sinus ostium. Due to the inflammation and the expansive character of the tumor, with the erosion of the bony walls, combined forms can develop, with the involvement of two or more sinuses, most frequently with fronto-ethmoidal localization.The authors carry out a clinical retrospective study on 25 cases of mucoceles of the paranasal sinuses, diagnosed and treated in the ENT Clinic of the “Sfantul Spiridon” Emergency Clinical Hospital Iasi, during 2015-2019. The authors insist on aspects related to clinical and radiological diagnosis (CT scanner), as well as surgical treatment by external approach.The postoperative evolution is generally simple, with full recovery, without complications or recurrences.The diagnosis of the mucoceles of the paranasal sinuses consists in radiologic techniques by preoperative CT scan examination, intraoperative macroscopic aspect and histopathological result.Surgical approach with complete excision of the tumor and creating a new sinusal drainage path prevents the occurrence of recurrences.

Abstract:

This study aims to determine the correlation between the anatomical variations of nasal cavity and paranasal sinuses and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan. The samples are 36 patients with age ≥ 18 years. The method is Chi Square test / Fisher's test and Spearman’s rho test. The results showed that anatomical variations of the nasal cavity and paranasal sinuses from most of the patients who underwent paranasal sinuses CT scan had septal deviation n = 29, p = 0.007 (p <0.05) and concha bullosa n = 15, p = 0.029 (p <0.05). There was a significant correlation between total anatomical variation and quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan p = 0.025 (p <0.05). There was no correlation between the anatomical variations of frontal cells, agger nasi cells, ethmoid bulla, uncinate process and haller cells and the quality of life based on SNOT-22 score in the patients who underwent paranasal sinuses CT scan.

Abstract:

Although a variety of theories have been proposed about functions of the paranasal sinuses, not one is clear today. Nonetheless, paranasal sinus–related diseases are associated with a high rate of morbidities. Therefore, it is essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool displaying anatomic variations and diseases. Because paranasal sinus development is a complex and long-lasting process, there are great structural variations between individuals. Several degrees and combinations of aplasias and hypoplasias have been reported; however, there is only one case of total paranasal sinus aplasia in the literature. Here, we present the second case of total paranasal sinus aplasia. Paranasal sinus development, functions of the paranasal sinuses, and the role of CT were evaluated.

Abstract:

Parietal edema/edematous syndrome, appearing in isolation in the paranasal sinuses, is the most common radiographic finding. However, the transformation of the syndrome into polypous tissue, the relationship with the formation of clinical forms of rhinosinusitis are poorly understood. Objective. To reveal the relationship of edematous syndrome of the mucous membrane of the paranasal sinuses with meteorological elements (humidity, temperature, precipitation, wind speed). Describe the mechanism of the pathogenetic relationship between increased water vapor pressure and edematous syndrome of paranasal sinuses. Materials and methods. The study included 504 people who performed computed tomography in the units of Saint Petersburg City Hospital No. 40 in 2019, of which 243 were men, 261 were women. Age from 33 to 56 years old, mean age 46.45 ± 1.87. On each of the three selected days of the month, 14 patients were determined (methods of random sampling) who underwent CT of paranasal sinuses. Results. The processes of condensation in the sinuses were evaluated using a computer thermotechnical calculation. A connection was found between the edematous syndrome of the mucous membrane of the paranasal sinuses and meteorological elements (moderate correlation between relative humidity and the presence of edema, a strong correlation between the average wind speed and edema of paranasal sinuses). The mechanism of pathogenetic connection of increased water vapor pressure with edematous syndrome of paranasal sinuses is described. The main types of pathological processes were identified: film condensation with a dew point on the mucosal surface, interstitial condensation with a dew point in the thickness of tissues, and various combinations thereof.

Abstract:

The relationship between sinusitis and ischemic stroke is unexplored. The anatomic proximity between the paranasal sinuses and the internal carotid artery suggests that inflammation of the sinuses could easily extend to the intracranial vasculature. We report 4 patients with acute ischemic stroke and extensive disease of the paranasal sinuses. All patients had large vessel stroke involving the internal carotid artery territory. All patients had extensive disease of the sphenoid and other sinuses. The sinus disease was demonstrated by magnetic resonance imaging. These case report observations suggest a relationship between inflammation of the paranasal sinuses, particularly sphenoid sinusitis, and ischemic stroke.

Abstract:

Osteoma of the paranasal sinuses is a benign, slowly growing, most often solitary, formation. Detection of multiple osteomas of the paranasal sinuses is casuistic in nature. According to the literature, their occurrence is 0.13% in computed tomography of the paranasal sinuses. Clinically osteoma is asymptomatic. Multiple osteomas of the paranasal sinuses may be a manifestation of Gardner’s syndrome, which was first described in 1953 as a triad of symptoms: multiple colon polyps, multiple osteomas, and skin and subcutaneous soft tissue tumors. In addition, patients are also diagnosed with dental and skeletal anomalies, retinal pathology. Gardner’s syndrome is hereditary autosomal dominant. The article presents a clinical case of a patient with multiple osteomas of the paranasal sinuses. The practical interest of this observation is its rare occurrence and the need to discuss options for choosing a therapeutic, including surgical, tactic and further management (dynamic monitoring, additional examination) of the patient. The case of multiple osteomas seems to be a rare pathology, possibly hereditary. Despite the benign nature of osteomas of the paranasal sinuses, the patient should be informed about the need for further observation, should be included in the dynamic observation group, and additionally examined by related specialists (dermatologist, dentist, gastroenterologist, ophthalmologist).

Abstract:

BACKGROUND Computerized Tomography (CT) scan plays a very important role in decision making before planning any surgical intervention on paranasal sinuses and is also the modality of choice during management and post-surgical follow-ups. Knowledge of different morphologies of paranasal sinuses is an important prerequisite for surgical decision making. This study was done to describe the impact of gender and age on anatomical and morphological presentations of paranasal sinuses using CT in the North Indian Population. METHODS A cross-sectional type of descriptive study was conducted in the Department of Anatomy in collaboration with the Department of Radiodiagnosis of M. L. N. Medical College and Kriti Scanning and Research Centre, Allahabad (Prayagraj) Uttar Pradesh, to describe various morphological presentations of paranasal sinuses. Based on the findings, the gender and age group variations of paranasal sinuses were evaluated and discussed along with the types of the frontal air cells and concha bullosa. RESULTS Overall 120 subjects were analysed based on their CT-scan findings (72 males and 48 females). The frequencies of major sinus variations were observed as Onodi cells in 19.2 %, Concha bullosa in 47.5 %, Frontal air cells in 25 %, Maxillary sinus septation in 7.5 % and Supraorbital cells in 15 % of the study population. CONCLUSIONS Anatomical variations of paranasal sinuses are very common. These variations must be identified by the radiologists in preoperative computerised tomography evaluation to reduce the risk of intraoperative complications. CT scan provides a virtual roadmap to the surgeon and improves the success of management strategies. KEY WORDS Anatomical Variations, Paranasal Sinuses, Concha Bullosa, Onodi Cell

Abstract:

The pediatric nasal cavity and paranasal sinuses, when compared to those in adults, differ not only in size but also in proportion. Knowledge of the unique anatomy and pneumatization of children's sinuses is an important prerequisite to understanding the pathogenesis of sinusitis and its complications. It is also important in evaluation of radiographs and in planning surgical interventions. In order to study the development of the paranasal sinuses in children and relate clinical anatomy to sinus surgery, the sinuses in 102 pediatric skulls and cadaver heads were measured. The results were classified by stage of development into 4 different age groups: newborn and 1 to 4, 4 to 8, and 8 to 12 years. The characteristics of each group and their clinical importance for paranasal sinus surgery are described.

Abstract:

ABSTRACT Introduction Nasal polyps are pedunculated, edematous, prolapsed mucosa of the paranasal sinuses. These polyps commonly arise around the ostia of the paranasal sinuses in the middle meatus. Discussion The commonest sites of polyp formation are the ethmoid sinuses and maxillary sinus. Rarely polyps may also arise from the other paranasal sinuses. Sites in the nasal mucosa other than the paranasal sinuses are very rare, though polyps arising from the septum have also been reported. The etiology of nasal polyposis is believed to be due to an inflammatory reaction of the nasal and paranasal sinus mucosa. Conclusion In addition to the theory of altered airway dynamics in the middle meatus, there also appears to be a link between polyp formation and preceding chronic inflammation. This is the most likely explanation for the origin of polyps in unusual sites. We present here a case of a nasal polyp arising from the floor of the nasal cavity. There are no previous records or reports in literature of this unusual site of origin of a nasal polyp.

Abstract:

AbstractIntroduction:The paranasal sinuses, comprising the frontal, maxillary, ethmoid and sphenoid sinuses, have caused consternation and debate over their true function over the course of nearly two millennia. This review aims to define the current evidence for the role of the paranasal sinuses, and to attempt to propose an answer to the question ‘why do we have paranasal sinuses?’Materials and methods:A literature review was conducted, searching Medline (1966–2007), Embase (1988–2007), the Cochrane Library and Ovid (1966–2007). Combinations of the following search terms were used: ‘paranasal sinuses’, ‘physiology’, ‘anatomy’, ‘function’, ‘evolution’ and ‘rhinology’. Any relevant references were cascaded to increase detection of pertinent information. The current, tenable theories identified in the literature review are discussed and the evidence for them critically analysed.Results:The current, tenable theories are described.Discussion:The paranasal sinuses may act simply to improve nasal function; certainly, it has been demonstrated that they may act as an adjunct in the production of nitric oxide and in aiding the immune defences of the nasal cavity. However, there is a distinction between utility and evolutionary origin. It may still be that the sinuses arose as an aid to facial growth and architecture, or persist as residual remnants of an evolutionary structure with an as yet unknown purpose, and in doing so have found an additional role as an adjunct to the nasal cavity.

Abstract:

The characteristics of the paranasal sinuses (maxillary, frontal, sphenoid and ethmoid sinuses) are information of great relevance to Forensic Sciences, as their images can be used for human identification purposes. Due to their particularities, the paranasal sinuses provide valuable information for human identification, reducing the risk of errors during investigation by experts. Such structures are visualized from several imaging exams. This study evaluates the possibilities of human identification through the analysis of the paranasal sinuses, as well as the effectiveness of their analysis in estimating sex, age and ancestry. A comprehensive search was performed in the PubMed, SciELO, LILACS, and Web of Science databases. As inclusion criteria, texts that addressed the subject were selected. Imaging analysis of the frontal, maxillary and sphenoid sinuses is a useful tool for human identification, as well as for estimating sex, age and ancestry; usually provides a high level of accuracy. Regarding the ethmoid sinus, research is indicated to verify its use in human identification, as no publications on this specific subject were found. Additional research must be carried out (especially three-dimensional analysis of the paranasal sinuses), to develop standardized protocols, improving the work of experts, helping justice and society.

This study aims to analyze the management of the radiographic examination of the paranasal sinuses and to analyze the use of X-ray projections for the examination of the paranasal sinuses in patients with clinical sinusitis at Mayapada Hospital Lebak Bulus. This research method is descriptive qualitative with secondary data analysis approach in January 2022. The study sample consisted of six patients who underwent examination of the paranasal sinuses with clinical sinusitis. The research process includes literature study, observation and interviews. The instruments used are worksheets and documentation tools. Interviews were conducted with two radiographers and one radiology specialist. The result of this research is that the examination of the paranasal sinuses in clinical sinusitis can be performed using two or three projections. Examination of two projections, consisting of a parietoacanthial projection (water's method open mouth) and a lateral projection. Three-projection examination consists of lateral projection, parietoacanthial projection (water's method open mouth) and Posteroanterior or PA axial projection (caldwell method).

Abstract:

Objectives: To analyze the occurrence of malignancy in nose and paranasal sinuses and to identify the common type of nose and paranasal sinuses tumor. Study Type: Analytical study Place and Duration of Study: ENT Outpatients Department, Rai Medical College Teaching Hospital, Sargodha from 1st April 2017 to 31st March 2021. Methodology: Fifteen patients with nasal endoscopy performed for the diagnosis of tumors were enrolled. Lesion site and extent were determined through computed tomography imaging. Biopsy of each patient was performed under local anesthesia and histopathological findings were documented. Results: The mean age of patients was 55.3±3.3 years. Tumors of nose and paranasal sinuses were more common in the males (66%) than in the females (34%). It is revealed that majority of cases were diagnosed with squamous cell carcinoma 12 (80%) cases, 2 (13.3%) cases were diagnosed as adenocarcinoma and 1 (6.7%) case was diagnosed as adenoid cystic carcinoma. Conclusion: Squamous cell carcinoma was the main histopathological category of nose and paranasal sinuses tumor.

Abstract:

The influence of the maxillary sinuses in acoustic rhinometry (AR) has not been evaluated, and this is the aim of the present study. We examined six subjects with AR and magnetic resonance imaging (MRI) after nasal decongestion to compare the area-distance relationships determined by the two methods. From the MRI data we obtained copies of the nasal cavities with and without maxillary sinuses, which were made in plastic by a stereolithographic method. AR curves from models without maxillary sinuses differed from AR curves with sinuses included but were in agreement with MRI curves without inclusion of sinuses. A similar difference in AR was seen in two subjects before and after the nasal cavities were flushed with saline to fill up the maxillary sinuses. The measured volume in the first 50 mm of the nasal cavity models was unaffected by the sinuses, but the volume in the first 70 mm corresponding to the length of the nasal cavity septum was increased slightly but significantly (from 10.8 to 11.3 cm3; P = 0.05). The presence of maxillary sinuses increased the volume of the epipharynx (70-100 mm from the nostril) from 12.2 to 21.3 cm3 (P < 0.01), and this increase was not due to the influence from the contralateral nasal cavity. We conclude that the maxillary sinuses may significantly contribute to the acoustically determined areas in the posterior part of the nasal cavity and the epipharynx, especially during decongestion, and may explain a part of the difference between area-distance curves obtained by AR and MRI, whereas contribution from the contralateral nasal cavity does not.

Abstract:

The airways should be considered as a functional unit. Indeed, disorders involving the upper respiratory tract (URT) spread to the lower respiratory tract (LRT). Modern functional anatomy divides URT in three, mutually dependent, “junction boxes”: i) the ostio-meatal complex (OMC), ii) the spheno-ethmoidal recess (SER), and iii) the rhinopharynx (RP). The first is the most interesting as it joins the anterior paranasal sinuses with the nose. The correct ventilation and the effective mucociliary clearance of these “three pathophysiologic junction boxes” condition the healthy physiology of the entire respiratory system. The OMC, SER and RP obstruction is the first pathogenic step in the inflammatory cascade of the rhino-sinusal-pharyngeal disorders. The inflammation of the respiratory mucosa is the main pathogenic factor for “airway obstruction” that may be generically defined as a heterogeneous group of pathologies. Moreover, the bacterial biofilms are an important local cause of recurrent diseases: they are a strategic modality of survival set up by bacteria and the main cause of their resistance to systemic antibiotic therapy.
