“…This study shows that there is sexual dimorphism with most of the FS, MS, IMD and BZD dimensions higher in males with MS and BZD significant. This is similar to other reports [5,10,[23][24][25][26][27][28] but contrary to study by Ariji et al which reported no significant difference between the genders [21]. Our study shows that generally, the left FS has higher dimensions than the right which is similar to other reports [29][30][31][32], but in contrast to another study done in India in which the right FS has higher values [27].…”

Background: Radiological identification is important in clinical, surgical and forensic medicine particularly in the absence of comparative deoxyribonucleic Acid (DNA) samples and fingerprints. Aim is to establish the morphometry of frontal sinus (FS), maxillary sinus (MS) and bizygomatic distance (BZD) and their relationship with age and gender in Igbos and Ogonis of Nigeria using computed tomography (CT). Methods: Head CT scans of 625 subjects (477 Igbos and 148 Ogonis) between 18 and 85 years, showing normal FS, MS and BZD, were measured using DICOM viewer software. The Igbos and Ogonis were 247 males and 230 females; 84 males and 64 females respectively. The height, width and depth of the sinuses, intermaxillary sinus distances (IMD) and BZD were measured in centimeters (cm). The data were analyzed using SPSS version 20 and difference between groups was obtained using one way ANOVA. P-value less than 0.05 was considered as statistically significant. Results: Mean values for the right and left MS volume for the Igbos are 13.79 ±10.91 and 13.81±11.03 and for the Ogonis 20.84±5.83 and 20.19±5.59 cm respectively. All FS dimensions are higher in the Igbos (P<0.001) except right FS depth. Mean IMD are 3.64±0.50 and 3.39±0.45 cm in the Igbos and Ogonis respectively (P<0.001). Ogonis have higher BZD (P>0.05). In both groups, males had larger values in both FS depth, MS dimensions and BZD (P<0.001). Age correlated positively with left FS height and IMD. Prevalence of unilateral FS aplasia was 3.35% on the right and 1.47% on the left among the Igbos while the Ogonis have 2.03% on the right and 2.70% on the left. Bilateral FS aplasia was 2.94% among the Igbos but not observed among the Ogonis. Conclusion: Normative values is established. Ethnic differences exists with Igbos significantly having higher values of FS and IMD while in the Ogonis, the MS dimensions are higher. These findings would act as a guide for facial reconstructive surgeries, forensic experts and classification of fossil remains in anthropology.

“…In the cancellous bone the trabeculae were thin, allowing ample medullary space, frequently engaged by adipocytes and fat cells leading to bone resorption. (16) In a study about age-related morphological changes of the maxillary sinus which performed on 70 cases (36 males and 34 females, mean: 45.4 years) include each ten cases from the second to seventh decade, six cases in the eighth decades and four cases in the ninth decades. They showed that; the poster-anterior, medial-lateral diameters and the area had their peaks in approximately the third to fifth decades.…”

Aim: This study was designed to evaluate the possible variation in dimensions of maxillary sinuses in Egyptian population using CBCT. Subjects and Methods: 120 CBCT of bilaterally maxillary sinuses of adult Egyptians of both sexes with ages ranging from 20 to 50 years were randomly selected. Then CBCT images were grouped according to gender, age and side. Three measurements in millimeters (width, depth, height), were taken on the axial and coronal cross sections. Results: Right and left height was statistically significant difference in male group than in female group (P<0.005). There was not statistically significant difference in dimensions between any age group and any another age group. It was difference between right and left sides of maxillary sinus, but this difference was not statistically significant. Conclusion: mean values of maxillary sinuses dimensions of males were found to be larger than these of females and this difference was statistically significant only for height dimensions.

“…The volumetric and surface data of the paranasal sinuses were sorted according to age since the factor of ontogeny considerably affects the shape of these structures (e.g., see Ferreira et al, 2021). The linear distances were sorted according to sex for their value in detecting sexual dimorphism in the sinus anatomy (Bangi et al, 2017; ELbaz et al, 2019; Umeres‐Alvis, 2019). All quantitative data were ordered using spreadsheet software and expressed as averages and standard deviation.…”

This study explores for the first time the shape, volume, and configuration of nasal cavity structures of the endangered Patagonian huemul deer via computed tomography (CT). Three‐dimensional (3D) reconstructions derived from data sets obtained from five Patagonian huemul deer skulls were analyzed. Using semiautomatic segmentation, 3D models were created of all the sinus compartments and nasal conchae. Volumetric measurements were taken of seven sinus compartments. The Patagonian huemul deer has a wide, large nasal cavity, with an osseous nasal aperture typical of cervids and a choana with characteristics that differentiate it from the pudu and roe deer. It also has six nasal meatuses and three nasal conchae, with the ventral nasal concha having the greatest volume and surface, which given its extension ensures a greater ability to humidify and heat the air. Further analysis showed the complex system of paranasal sinuses to be characterized by a rostroventral and interconnected group, where communication with the nasal cavity is common through the nasomaxillary opening, and a caudodorsal group that communicates with the nasal cavity through openings in the nasal meatuses. Our study of the endangered Patagonian huemul deer documents an intricate, and in some nasal cavity structures, unique morphological construction which may predispose it to higher rates of sinonasal afflictions due largely to its nasal complex anatomy, thus affecting its high cultural value.
