Background/Aim. In the course of identification, skeletal remains are used to determine the gender, age, and height of the body. The pelvic bone, skull, and femur were commonly used to determine gender; however, modern radiology tech-niques have enabled the use of other bones of the skeletal system (all long bones, scapula, clavicle, metacarpal and meta-tarsal bones, vertebras, ribs, etc.). The aim of this study was to determine whether certain anthropometric characteristics of the distal femur and proximal tibia are indicative of gender differences. Methods. The respective research has been car-ried out between 2011 and 2014 at the Institute of Pathology and Forensic Medicine and Institute of Radiology of the Mili-tary Medical Academy in Belgrade on 203 subjects (152 men and 50 women), between 11 and 63 years of age (35.50 ± 12.98). Diagnostic magnetic resonance imaging (MRI) imag-ing of the living persons' knees was used. Measures taken in-cluded the longest mediolateral diameter of the distal femur condyle, the mediolateral diameter of the proximal tibia con-dyle and the diameter of the proximal tibia intercondylar em-inence. Descriptive statistics and the Student's t-test were used for statistical analyses of data. Results. The mediolateral diameter of the distal femur in men was from 7.70 cm to 9.70 cm (8.80 ± 0.39 cm), and in women from 6.60 cm to 8.50 cm (7.62 ± 0.39 cm). The mediolateral diameter of the proximal tibia in men was from 7.20 cm to 9.30 cm (8.09 ± 0.38 cm), and in women from 5.90 cm to 8.00 cm (7.04 ± 0.36 cm). The mediolateral diameter of the proximal tibia intercondylar eminence in men was from 1.00 cm to 2.30 cm (1.44 ± 0.21 cm), and in women from 0.90 cm to 2.00 cm (1.33 ± 0.21 cm). The measures obtained showed a gender-specific statis-tically significant difference. Conclusion. The mediolateral diameters of the distal femur condyle, proximal tibia condyle and proximal tibia intercondylar eminence are indicative of gender-specific differences and may be used in the procedure of determining gender based on skeletal remains. © 2021 Inst.

Third-party payers request objective confirmation of the nasal septum deviation (NSD) severity by computed tomography (CT) before authorizing financial support for septoplasty. Previous studies have provided contradictory results related to the link between obstruction severity and CT-measured angle of the NSD. The aim of this study was to investigate whether the diverse CT morphology of NSDs (including previously neglected types and shapes) could predict obstruction severity. The study included 225 patients with NSD. The CT morphology of the septum was analyzed using 5 different classifications of NSD that are commonly used in the clinical practice and research. The angle of NSD was also measured. Nasal obstruction was assessed by the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire. A relationship between CT morphology and the angle of the NSD and NOSE scores was analyzed using appropriate regression models. Patients with NSDs located in the anterior part of the septum always have some degree of nasal obstruction, while those with posterior NSDs did not necessarily report obstruction symptoms no matter how complicated NSD they have. Regression analysis did not reveal any causal relationship between NOSE scores and CT morphology and the angle of NSD. The presence of spurs and whether they divide nasal passages have no statistically significant predictive effect on the obstruction severity. The CT morphology and the angle of the NSD could not predict severity of the nasal obstruction. Requesting CT examination just to objectively confirm nasal obstruction is not justified. © The Author(s) 2019.

Introduction: The impact of the nasal septum morphology on the severity of obstruction symptoms has not been fully explored. Objective: This study aimed to investigate whether the morphology of the deviated nasal septum assessed by computed tomography may explain nasal obstruction severity. Methods: The study included 386 patients who were referred to the computed tomography examination of the paranasal sinuses. Patient selection criteria were the absence of facial anomalies, facial trauma, nasal surgery, and sinonasal tumors. Computed tomography images were used to estimate deviated nasal septum prevalence, the prevalence of Mladina's seven types of deviated nasal septum, and to measure the deviated nasal septum angle. Nasal obstruction severity was assessed by the nasal obstruction symptom evaluation, NOSE scale. The relationship between NOSE score, deviated nasal septum morphology, and deviated nasal septum angle was performed by a statistical regression model on the reduced sample of 225 patients. Results: The prevalence of deviated nasal septum was 92.7%. Type 7 deviated nasal septum was the most frequent (34.2%) followed by type 5 (26.2%) and type 3 (23.6%). The worst NOSE scores were recorded in the type 2 deviated nasal septum (45.00 ± 28.28). The mean deviated nasal septum angle in patients with nasal obstruction was 8.5° ± 3.24. NOSE scores were not significantly associated with deviated nasal septum types and angles. Conclusion: Patients with different types of deviated nasal septum have different NOSE scores. Computed tomography morphology of the deviated nasal septum could not fully explain the severity of nasal obstruction. © 2020 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial
