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.

Full text
Abstract:
This study aims to design and develop effervescent proliposomes that could disintegrate in water and liberate liposomes, and to investigate the potential suitability of liposomes generated for aerosolization to target paranasal sinuses. Novel effervescent proliposomes prepared with Soya phosphatidylcholine (SPC) and Dipalmitoylphosphatidylcholine (DPPC) successfully generated stable liposomes with an improved disintegration time of less than 5 min. Differences in lipid composition were found to influence liposome size and drug entrapment of the hydrophobic drug Beclometasone dipropionate (BDP). Mannitol-based formulations developed with DPPC:Chol (1:1) produced liposomes of 7.54±0.15 µm with a drug entrapment efficiency of 82.15±8.29%. Addition of the mucoadhesives alginic acid or chitosan to effervescent proliposomes made with SPC was found to hamper BDP entrapment in liposomes. Effervescent proliposomes produced SPC:Chol liposomes that also proved beneficial for entrapment of the hydrophilic drug Xylometazoline hydrochloride (XH). The Pari Sinus (pulsating aerosol technology) and Pari Sprint (non-pulsating technology) nebulizers were used for liposome delivery to a nasal cast. Choice of carrier did not affect the liposome’s ability to withstand shearing. A novel system of a Sar-Gel® (water indicating paste) coated clear nasal cast fixed to a two-stage impinger system was set up to analyze drug deposition within the nasal cast cavity. Sinus drug deposition with effervescent mannitol, DPPC:Chol formulation was observed to be highest at 48.45±2.75 cm2 with pulsation compared to deposition of 35.52±11.11 cm2 without pulsation. Drug distribution studies indicated that the Pari Sinus deposited 10.47±2.9% drug, while the Pari Sprint deposited only 4.6±1.4%. The degree of drug loss was higher with conventional liposomes in the Pari Sinus nebulizer, indicating that the degree of bilayers disruption depended on formulation.

Abstract:
Sinonasal and dental diseases can be a serious disorder in horses due to the persistence of the former and the common extension of the latter to the supporting bones of the skull. The diagnosis of equine sinonasal and dental disease can be challenging due to the complexity of these and adjacent anatomical structures, and therefore the use of advanced imaging, including computed tomography (CT) has greatly increased recently. A major aim of this study was to improve the morphological characterization of the sinuses and cheek teeth in normal horses of different ages. These studies defined the volumes of the 7 different sinus compartments; showed that the volume of the different compartments increase with age; that in contrast to accepted findings, the Triadan 09 alveoli is located in the caudal maxillary sinus (CMS) in 13% of the youngest group and the Triadan 10 alveoli is fully within the rostral maxillary sinus (RMS) in 53% of cases. The infraorbital canal was found to be susceptible to apical infection-related damage in horses < 2 years of age (< 2 y.o.) due to the intimate relationship of this canal and the medial aspect of the maxillary cheek teeth alveoli. The mean positions of the clinical crowns and apices of the maxillary Triadan 11s were 2.48 cm (adjusted 5.2% of head height) and 2.83 cm (adjusted 6.2% of head height) more rostral, respectively in horses >16 y.o. compared to horses < 6 y.o., consistent with rostral dental drift. Measurements of dental drift could provide further objective radiographic guidelines on ageing horses by dental imaging and also help our understanding of the aetiopathogenesis of cheek teeth diastemata. This study also found that the reserve crown length decreased from a mean of 4.7 cm (adjusted 19.7% of head height) in the youngest (< 6y.o.) group of horses to a mean of 2.9 cm (adjusted 10.5% of head height) in the oldest group (>15y.o.), with the 06s and 09s having the shortest reserve crowns. These data are useful reference information for clinicians and radiologists in the diagnosis and treatment of equine sinonasal and dental disease. Morphological characterization of the ventral and dorsal conchal bullae in horses of different age using CT described the age-related difference in sizes of these structures (smaller in younger horses). In the ventral conchal bulla, this reduction in volume was probably related to protrusion of the large dental alveoli in young horses into the nasal cavity and bulla. Bullae linear measurements and volumes were also associated with head size. The anatomical position of both bullae was associated with specific maxillary cheek teeth, thus increasing the diagnostic value of conventional radiography in the investigation of bulla disease and providing landmarks for the surgical treatment of this disorder. Skull shape analyzed with the use of Procrustes statistical analysis showed landmark variability between different age groups and in particular, high landmark variability between young (< 5y.o.) and old (>16y.o.) horses and less landmark variability between adult (6-15y.o.) and old horses. Future studies could investigate changes in the equine skull in relation to genotype to characterize breed-related diseases affecting teeth and sinonasal compartments. In the second part of the study, 32 infected maxillary cheek teeth extracted from clinical cases were evaluated grossly and histologically and these pathological results were compared to the pre-extraction radiographic and CT imaging findings. This study showed a high sensitivity (97%) of CT in detecting changes in teeth affected by apical infection. In the third part of the study, 30 cheek teeth assessed as being abnormal based on oral, radiographic and CT examinations were extracted along with their alveoli from 27 cadaver heads. Gross and histological examination findings from these teeth and alveoli were compared to the pre-extraction imaging findings, again showed high sensitivity (96.4%) of CT in diagnosing cheek teeth apical infection. Additionally, CT showed a high correlation with histology in detecting dental infection related alveolar bone changes including alveolar bone lysis, sclerosis and bone thickening. This aspect of the study was also the second largest pathological study of equine apical infection published to date and thus has also improved our understanding of the pathogenesis of this disorder. In conclusion, CT was shown to be an excellent imaging modality for improving the morphological characterization of the sinuses and teeth in normal horses of different ages, and thus also improving the value of this modality in diagnosis and treatment of disease affecting sinonasal and dental structures. This study also objectively showed the high sensitivity of CT in detecting cheek teeth apical infection in horses as compared to radiography, including by assessment of alveolar bone changes. Overall, the results of this project improve morphological knowledge of the equine skull and teeth and will have direct clinical benefits by improving the diagnosis and thus the treatment of equine sinonasal and dental disease.

Abstract:
Background: The contribution of the nasal and paranasal cavities to the vocal tract resonator properties is unclear. Here we investigate these resonance phenomena of the sinonasal tract in isolation in a cadaver and compare the results with those gained in a simplified brass tube model. Methods: The resonance characteristics were measured as the response to sine sweep excitation from an earphone. In the brass model the earphone was placed at the closed end and in the cadaver in the epipharynx. The response was picked up by a microphone placed at the open end of the model and at the nostrils, respectively. A shunting cavity with varied volumes was connected to the model and the effects on the response curve were determined. In the cadaver, different conditions with blocked and unblocked middle meatus and sphenoidal ostium were tested. Additionally, infundibulotomy was performed allowing direct access to and selective occlusion of the maxillary ostium. Results: In both the brass model and the cadaver, a baseline condition with no cavities included produced response curves with clear resonance peaks separated by valleys. Marked dips occurred when shunting cavities were attached to the model. The frequencies of these dips decreased with increasing shunting volume. In the cadaver, a marked dip was observed after removing the unilateral occlusion of the middle meatus and the sphenoidal ostium. Another marked dip was detected at low frequency after removal of the occlusion of the maxillary ostium following infundibulotomy. Conclusion: Combining measurements on a simplified nasal model with measurements in a cadaveric sinonasal tract seems a promising method for shedding light on the acoustic properties of the nasal resonator.

Resumo: Opacificações dos seios paranasais podem ser encontradas incidentalmente em tomografias de pacientes sem rinossinusite. Esses achados freqüentemente são desprovidos de significado clínico, mas podem trazer dilemas diagnósticos quando são intensos. Objetivos: verificar se anormalidades tomográficas incidentais dos SPN em crianças e adolescentes sem rinossinusite implicam em maior risco de desenvolvimento posterior de sintomas do trato respiratório superior. Casuística e Método: foi realizado um estudo de coorte com pacientes entre zero e 18 anos, submetidos à tomografia computadorizada do crânio por indicações não relacionadas à rinossinusite. As opacificações sinusais foram aferidas por um escore, a razão opacificação/desenvolvimento. A evolução clínica dos pacientes foi então avaliada por questionários durante o mês que se seguia ao exame. Resultados: dos 106 pacientes incluídos, as opacidades acometeram 56%, a maioria representada por espessamento mucoso discreto. Opacidades mais intensas, ditas suspeitas (escore = 15) impuseram maior risco de desenvolvimento de sintomas ao longo do seguimento, com odds ratio de 2,74 (IC95%: 1,10 - 6,83) em relação aos exames normais ou a opacidades discretas. Conclusão: opacidades são encontradas incidentalmente com freqüência em tomografias de crânio de crianças e adolescentes e quanto mais intensas elas são, maior é o risco de evolução posterior de quadros respiratórios
Abstract: Paranasal sinuses opacification are incidentally found on computed tomography of patients without rhinosinusitis. These findings are often of no clinical significance, however may cause diagnostic dilemmas when they are severe. Objective: to verify if incidental abnormalities of the paranasal sinuses on tomography of children and adolescents without rhinosinusitis raise the risk for development of superior respiratory tract symptoms. Methods: a cohort study was conducted on patients with ages varying from 0 to 18 years whose tomographic scans of the head were done for problems not related to rhinosinusitis. Sinuses abnormalities were measured by a score system called opacification-development ratio. Then periodical clinical follow-ups were undertaken by inquiry forms applied during the month next to the scan. Results: From a sample of 106 patients, opacities affected 56%, usually represented by mild mucousal thickening. Moderate and severe opacities, what was called suspicious (score = 15) imposed a higher risk of emerging respiratory symptoms during follow-up, at an odds ratio of 2.74 (CI95%: 1.10 - 6.83), compared with mild opacities or normal scans. Conclusion: Incidental opacities are frequently found on computed tomography of children and adolescents and the more severe they are, the higher the risk of progression to respiratory clinical manifestations afterwards

Abstract:
Chronic rhinosinusitis is a common disorder of chronic inflammation of the upper respiratory tract. It is associated with significant symptoms and impairment of the quality of life of sufferers. Despite recent advances in the medical and surgical management of chronic rhinosinusitis, there remains a population of patients who fail to obtain relief from their symptoms. Chronic inflammation of the mucosa of the nasal cavity and paranasal sinuses is one of the hallmarks of chronic rhinosinusitis. This inflammation is demonstrated by an increased number of chronic inflammatory cells, elevated levels of pro-inflammatory cytokines, increased expression of adhesion molecules and metaplastic changes in the epithelium. The current medical treatments for chronic sinusitis aim to reduce this inflammation and consequently improve symptoms. In recent years, evidence has emerged that macrolide antibiotics have an anti-inflammatory effect that is separate from their anti-bacterial effect. This effect was first described in the treatment of diffuse panbronchiolitis, a disorder of chronic inflammation of the lower respiratory tract. Following the success of macrolides in treating this condition it was trialed in chronic rhinosinusitis. Several open-label trials have subsequently demonstrated a beneficial effect. Laboratory studies have investigated the mechanism of the anti-inflammatory effect of macrolides. These have shown that macrolides effect cytokine production, inflammatory cell apoptosis, expression of adhesion molecules, neutrophil oxidative burst, bacterial virulence and mucociliary function. In this thesis we report a series of experiments designed to further investigate the mechanism of action and clinical effect of macrolides. In vitro studies using whole sections of chronic rhinosinusitis mucosa cultured for 24 hours in macrolide, prednisolone or control showed that macrolide and prednisolone produced significant reductions in the production of interleukin-5, interleukin-8 and granulocyte-macrophage colony stimulating factor. The same cultured specimens also showed a reduction in expression of transforming growth factor-?. No reduction was seen in the expression of the key pro-inflammatory nuclear transcription factor Nuclear factor-?B. In our in vivo experiments, biopsies were taken from chronic rhinosinusitis patients who had received a 3-month course of macrolide. These biopsies showed a reduction in the number of neutrophils present following treatment. There was no reduction in the number of other inflammatory cells or in the expression of TGF-? and NK-?B. We have performed the first ever double-blinded, randomized, placebo-controlled trial of macrolide in the treatment of chronic rhinosinusitis. Patients receiving macrolide showed significant improvements in saccharine transit time, nasal endoscopic scoring and symptom scores following a 12 week course. Patients with low levels of serum immunoglobulin E showed significantly improved outcomes compared to those with high levels. Interleukin-8 levels in nasal lavage fluid were significantly reduced in the patients with low levels of IgE following macrolide treatment. No improvements in any of the objective or subjective outcome measures were seen in the placebo-treated patients. We have performed a series of experiments investigating the anti-inflammatory effect of macrolide antibiotics from 'the bench to the bedside'. These experiments have provided insight into the mechanism of action of macrolides in the laboratory setting and evidence of a beneficial effect in the treatment of chronic rhinosinusitis patients.

No presente trabalho, foi realizado um levantamento das doses recebidas por pacientes pediátricos, em exames radiográficos convencionais dos seios da face, realizados no Recife, PE. Para a realização do estudo, foram selecionados dois hospitais que atendem ao Sistema Único de Saúde, com alta demanda de exames pediátricos. Os dados dos pacientes e os parâmetros de irradiação utilizados em 159 exames radiográficos dos seios da face de crianças, com idades entre 0 e 15 anos, foram coletados, sendo 103 radiografias realizadas na projeção lateral (radiografia cavum) e 56 radiografias realizadas nas projeções pósteroanteriores em fronto-naso (FN) e mento-naso (MN) (radiografias Caldwell e Waters, respectivamente). Inicialmente, foram efetuadas as avaliações de desempenho dos dois equipamentos de raios X pertencentes aos hospitais. A partir dos valores dos rendimentos dos tubos de raios X e dos parâmetros de irradiação empregados nos exames, foram estimados os valores de kerma no ar na superfície de entrada (Ka,e) e produto kerma no ar-área (PK,A). Os valores de kerma no ar nas regiões dos olhos e da tireoide foram estimados utilizando dosímetros termoluminescentes (TLD-100). As doses absorvidas médias nos órgãos e a dose efetiva foram estimadas com o software PCXMC® a partir dos dados antropométricos, parâmetros de irradiação e do kerma no ar incidente (Ka,i), obtido com o rendimento. Os resultados mostraram que os valores de Ka,e variaram entre 0,065 mGy e 1,113 mGy, para radiografias cavum, entre 0,13 mGy e 7,99 mGy, para radiografias na incidência Caldwell e entre 0,13 mGy e 10,12 mGy, para radiografias na incidência Waters. Os valores do kerma no ar na região dos olhos variaram entre 0,001 mGy e 0,968 mGy, nas radiografias cavum, e 0,011 mGy e 0,427 mGy, nas incidências Caldwelll e Waters (conjuntamente). Na região da tireoide, os valores de kerma no ar variaram entre 5 μGy e 932 μGy, para as radiografias cavum, e 2 μGy e 972 μGy, para as incidências Caldwell e Waters. 90% dos valores de Ka,e estimados para os exames realizados no Hospital B encontram-se dentro do recomendado pela comunidade britânica, enquanto todos no Hospital A encontram-se acima. O fato do Hospital B apresentar valores de Ka,e dentro do aconselhado não significa que seu serviço esteja otimizado, devido a grande quantidade de filmes rejeitados, cuja imagem apresentava-se clara e inapropriada para o diagnóstico, elevando a dose final recebida pelo paciente pela repetição do exame. Os altos valores de Ka,e devem-se, principalmente, à utilização indiscriminada da grade antiespalhamento, não recomendada para pacientes desta idade. Os valores de PK,A variaram entre 5,7 mGy.cm2 e 92,3 mGy.cm2 para as radiografias cavum, entre 24,4 mGy.cm2 e 340,3 mGy.cm2 para as radiografias Caldwell e, entre 34,0 mGy.cm2 e 378,3 mGy.cm2 para as radiografias Waters. A partir dos dados pode-se concluir que há necessidade de otimização dos procedimentos radiográficos.
In this study, a survey was conducted in order to assess doses received by pediatric patients ongoing conventional radiographs of the sinuses, performed in Recife, PE. For the study, two hospitals of SUS (Sistema Único de Saúde), with high demand for pediatric examinations, were selected. Patient data and irradiation parameters were collected for 159 radiographs of the children’s sinuses with ages between 0 and 15. Among those, 103 radiographs were taken on the lateral projection (cavum radiography) and 56 radiographs were taken in posteroanterior projections in fronto-naso (FN) and mento-naso (MN) (Caldwell and Waters radiographs, respectively). Initially, the performance of the two X-ray equipment was evaluated. Air kerma values at the entrance surface (Ka,e), and air kerma area product (PK,A) were estimated using X-ray tubes output and irradiation parameters used in the examinations. Air Kerma values on the eyes and thyroid were estimated using thermoluminescent dosimeters (TLD-100). The average absorbed organ doses and effective dose were estimated at the PCXMC® software using the anthropometric data, irradiation parameters and the incident air kerma (Ka,i) obtained with the x-ray tube output. The results showed that Ka,e values varied between 0.065 and 1.113 mGy for cavum radiographs; between 0.13 and 7.99 mGy for Caldwell’s view; and between 0.13 and 10.12mGy for Waters’ view. The air kerma values in at the eye region varied from 0.001 mGy to 0.968 mGy for cavum radiographs, and from 0.011 mGy to 0.427 mGy for Caldwell and Waters’ views (together). In the thyroid region air kerma values ranged from 5 μGy to 932 μGy for cavum view and from 2 μGy to 972 μGy for Caldwell and Waters’ views. Tests performed at Hospital B have shown that 90% of the Ka,e values estimated during exams are within the recommended values by British Commonwealth, while all the Ka,e values in the Hospital A were above it. However, even though Hospital B presented Ka,e values within recommended values, this service was not optimized, due to the large amount of rejected films, whose image were inappropriate for diagnosis resulting in increased dose by the patient re-examination. The high Ka,e values are due mainly to the indiscriminate use of anti-scatter grid, not recommended for patient ages assessed in this study. PK,A values varied between 5.7 and 92.3 mGy.cm2 for cavum radiographs, between 24.4 and 340.3 mGy.cm2 for Caldwell’s view and between 34.0 and 378.3 mGy.cm2 for Waters’ view. Thus, it was concluded that there is need for optimization of radiographic procedures.

A identificação biométrica de pessoas na área forense está em constante estudo para facilitar e melhorar as maneiras de identificação mediante a avaliação de diversas estruturas que podem ser utilizadas como características biométricas. Os seios paranasais, cavidades ósseas presentes no crânio, apresentam alta individualidade e permanência, podendo ser utilizados em sistemas biométricos forenses. As maneiras de representação digital dos seios paranasais são modalidades de exames médicos, conhecidos como raios-X e tomografia computadorizada. As imagens de raios-X como ferramentas para obtenção de características dos seios paranasais apresentam alta aplicação nos trabalhos correlatos, entretanto, nesta modalidade de imagem, algumas desvantagens, como a baixa qualidade de resolução dificultam a identificação dos seios paranasais. Com a tomografia computadorizada, uma nova avaliação pode ser realizada para a obtenção das características dos seios paranasais, visto que esta modalidade de exame gera uma sequência de imagens com qualidade superior, tornando a segmentação e extração de características dos seios paranasais mais simples, intuitiva e precisa, facilitando seu uso em sistemas de reconhecimento biométrico. O objetivo desta dissertação foi desenvolver um novo método de identificação humana utilizando estruturas dos seios paranasais, obtidas de imagens de tomografia computadorizada, como características biométricas. Este método propõe avanços significativos principalmente nas etapas de segmentação e extração de características, uma vez que a segmentação das estruturas dos seios paranasais é realizada de forma automática. As características propostas como descritores são baseadas nas regiões e nas formas das estruturas dos seios paranasais. Resultados experimentais obtidos sobre uma base de dados contendo 310 imagens de tomografia computadorizada mostraram que o método automático proposto nesta dissertação obteve taxa de segmentação medida pelo Coeficiente KAPPA igual a 88,52% na segmentação dos seios frontais e 79,30% na segmentação dos seios maxilares. Com relação à identificação de pessoas, o método proposto obteve, no melhor caso, 8,99% de taxa de erro igual (EER). Assim, nesta dissertação de mestrado concluiu-se que: os seios da face podem ser utilizados com êxito para a identificação forense de pessoas, em particular os seios frontais; que os descritores de forma para os seios frontais são mais efetivos do que os descritores de região para a identificação de pessoas, enquanto que para os seios maxilares, os descritores de forma não apresentam alto valor de discriminação entre os indivíduos e; que é possível automatizar o processo de segmentação dos seios frontais e maxilares utilizando-se imagens de tomografia computadorizada.
Biometric identification of people in the forensic field is constantly being studied to facilitate and improve the identification methods through the evaluation of several structures that can be used as biometric features. The paranasal sinuses, bone cavities present in the skull, have high individuality and permanence and can be used in forensic biometric systems. The X-rays and Computed Tomography are modalities of medical examinations used for the digital representation of the paranasal sinuses. X-rays images as a tool to obtain characteristics of the paranasal sinuses are highly applicable in the related works, however, in this imaging modality, some disadvantages, such as low quality resolution, make these structures harder to acquire. With computed tomography representation, a new evaluation can be performed to obtain the paranasal sinuses features, knowing that this exam modality generates an image sequence with higher quality, making the paranasal sinuses segmentation and feature extraction simpler, intuitive and precise, facilitating its use in biometric recognition systems. The objective of this master’s dissertation was the development of a new human identification method that uses paranasal sinuses structures as biometric features, obtained from computed tomography images. This method proposes significant advances, specially on the segmentation and features extraction stages, once the segmentation of the paranasal sinuses structures is performed automatically. The characteristics proposed for the feature descriptors are based on the region and shape of the paranasal structures. The experimental results obtained from a database composed by 310 computed tomography images presented that the automatic method proposed in this dissertation showed 88.52% of frontal sinuses segmentation and 79.30% of correct maxillary sinuses segmentation using the KAPPA coefficient. Relative to the persons identification, the proposed method presented in the best case 8.99% of EER. Therefore, in this master’s dissertation, it was concluded that: the face sinuses, and in particular the frontal sinuses, can be used with success for the forensic human identification; for the human identification based on the frontal sinuses the shape descriptors are more efficient than the region descriptors, while that for the human identification based on maxillary sinuses, the shape descriptors do not presented high discrimination performance and; it is possible to automate the frontal and maxillary sinuses segmentation process using computed tomography images.

Abstract:
Introduction: Forensic pathologists may be asked to identify the race group or sex of a cranium of unknown origin. Race group refers to geographic ancestry and sex is biological sex. An analysis of the volumes and measurements of human paranasal sinuses, namely maxillary, ethmoid, sphenoid and frontal sinuses, in dried crania of different race and sex groups (European and Zulu male and female) was undertaken to search for a new improved approach of classifying crania according to race and sex. This anatomical assessment of the human paranasal sinuses identifies race and sex variations in the paranasal sinuses. Variations in paranasal sinus volumes and measurements may mean a variation in anatomical landmarks. The best combination of sinus measurements was selected to classify a cranium according to race group and sex making this research relevant to the field of forensic medicine. Objectives: To compare the paranasal sinus volumes and measurements of dried crania of European and Zulu descent with respect to race group and sex and to develop a method of classifying a cranium according to race group or sex by using dimensions of the paranasal sinuses. Methodology: Documented, cadaver derived, dried crania were obtained from the Raymond A. Dart Collection of Human Skeletons, housed at the School of Anatomical Sciences at the University of the Witwatersrand, Johannesburg, South Africa. Age, race and sex were recorded for each cranium within the collection and hence within the study sample. 26 Adult European crania; 13 male, 13 female. Age range 19-75yrs (mean 49.42yrs) and 27 Adult Zulu crania: 13 male, 14 female. Age range 16-90yrs (mean 40.16yrs) was selected for this study. An additional cranium of unknown origin was also analysed in the research. European crania were from descendants of Europe living in South Africa and Zulu crania were obtained from Zulu patients who were part of the Zulu tribe of South Africa. 53 crania with intact paranasal sinuses (106 individual sinuses for each of the maxillary, ethmoid, sphenoid and frontal sinuses) were studied. In addition, 2 sinuses from the unknown cranium were analysed. The dried crania of European and Zulu origin were assessed by helical, multislice computed tomography using 1mm coronal slices. The area for each slice was obtained by tracing the outline of each slice. A volume was calculated by the CT machine that totaled the slices for each sinus. Measurements of width, length and height were also assessed, as were other craniometrical measurements. Statistical analysis was performed for all European and Zulu male and female sinuses in respect of volumes and measurements. Further statistical analysis searched for classification patterns. In addition, forty patients' scans from the European and Zulu male and female groups in Southern Africa were also assessed. CT scans of 10 adult European males, 10 adult European females, 10 adult Zulu males and 10 adult Zulu females provided 40 pairs of maxillary, ethmoid, sphenoid and frontal sinuses for analysis. Europeans were South African persons of European descent and Zulus were from the Zulu tribe of Kwa Zulu Natal in South Africa. Results: The aim of identifying race and sex differences in this anatomical region is achieved. Significant race and sex variations were found in the European and Zulu, male and female groups when analysing the volumes and measurements of the paranasal sinuses. The very best combinations of classifiable measurements were described and are being put forward as a new tool in human forensic identification studies. The significant sex classification figure of 91.8% by combining ethmoid, sphenoid and frontal paranasal sinus measurements, is a new discovery for using a combination of the sinuses. The significant race classification figure of 95.9 % is an excellent classification figure for classification according to race. This was done using the measurements of maxillary, ethmoid and total distance across the sinuses. All this was achieved by using the measurements of the paranasal sinuses in a European and Zulu, male and female population. Conclusion: Forensic race and sex identification of crania is now possible using a combination of measurements from the paranasal sinuses. A new approach to classifying a cranium into an race or sex group is revealed by way of using a new combination of paranasal sinus measurements. This discovery is of importance to forensic medicine in the realm of identification as it provides a measurable way of assigning race or sex to a cranium within a particular region. Other studies based on other race groups may add further value. What is clear is that the paranasal sinuses are now of established value when assessing race or sex group of a unknown cranium. A new tool for forensic race and sex identification is provided to the armamentarium of the forensic pathologist and associated disciplines.

Abstract:
Abstract: Endoscopic endonasal surgery developed as a logical consequence of more sophisticated knowledge of the pathophysiology of the paranasal sinuses. Also endoscopic treatment of various diseases of the nasal cavity and paranasal sinuses proved to be as effective as clas-sical methods. Ethmoidal bone is a basic anatomic area, where pathologic activities are formed or the natural extension for a minimally invasive approach from the natural nasal opening to the brain, so the knowledge of its anatomy and development is of the para-mount significance. Ethmoid labyrinth starts to develop in the third week of gestation from the pharyngeal apparatus, and reach its full size only at age 12. From a surgical point of view, the most interesting are the medial turbinates, the roof of the nasal cavity, the uncinate process and the bulla ethmoidalis. Through the transethmoidal approach we can access all the cells in the ethmoid sinuses, the frontal sinus, the anterior skull base, the orbital walls and its contents. The awareness that there might be anatomical variations also carries great importance. The central location of the ethmoid bone is actually an in-tersection inside the nasal cavity and the basic component for understanding the anatom-ical relationships and the physiology of the paranasal sinuses.

Abstract:
Introduction:The cavernous sinus is a venous plexus delimited by the dura mater and sited at the base of skull, laterally to the sella turcica and to the sphenoid sinus. The cavernous sinus thrombosis (CST) is a serious illness that may result from infection of any tissue drained by the cavernous sinus (septic thrombosis). Septic thrombosis (ST) may occur through the suppurative process by the level of the orbit, of the upper half of the face or paranasal sinuses , constituting a critical complication of sinusitis. Objectives: To verify the association between cavernous sinus thrombosis and sphenoid sinusitis in children, in the bibliographic productions of the last 10 years. Methods:This is an integrative literature review, with a search carried out in the database of the Medical Literature and Retrieval System onLine (MEDLINE), using a combination of the following Health Sciences Descriptors (DECS): “Sphenoid Sinusitis” and “Thrombosis” And “ Cavernous sinus” in “ Children ”. Incomplete studies were excluded from the research, carried out before 2012, totaling 7 bibliographic studies for detailed analysis. Results:CST can result from infection of any tissue drained from the cavernous sinus. This includes the face, tonsils, soft palate, teeth and ears.Only 15% of cases of CST in patients up to 12 years of age, originated from the paranasal sinuses. However, more recent studies advance that sinusitis is currently the most common etiology. When the sinuses are the cause of CST, the sphenoid sinus emerged as the most common primary source of infection predisposing to CST, since it has important anatomical relationships with the cavernous sinus. Streptococcus has been reported as the most common organism associated with sphenoid sinusitis. Conclusion:Although CTS is a rare clinical condition, acute and persistent sphenoid sinusitis can progress to such a condition, despite medical treatment. The main support of treatment includes early diagnosis, aggressive intravenous antibiotics and appropriate surgical treatment.
