Background: The clavicle, modified long bone, presents morphological and bilateral variations. This may be due to genetic factors, hormones, or environmental and occupational influences. Anthropometric studies in clavicle of Nepalese population using radiograph has not been reported to best of our knowledge. This study, aimed to determine the sexual dimorphism and bilateral asymmetry of clavicle in Nepalese Population using Postero-Anterior Chest X Ray. Methods: Chest x-rays with normal and clearly visible both clavicles of 1260 Nepalese adults (591 male, 669 female), aged above 20 years were utilized. Inbuilt software "Computed Radiography Fuji Computer System 7" was used for measurements (in centimeter) of sternal head length, acromial end length, mid shaft diameter and length of clavicle. Demarcating point and identification point were calculated. Patients having history of clavicles fractures in the past were excluded. Results: All the parameters in male is greater than female which is significant except Length/Mid Shaft Diameter. Similarly, all the parameters of right clavicle is significantly greater than left clavicle in both sexes except Sternal Head Length and Mid Shaft Diameter. Demarcating point calculated from length of the clavicle (right >16.17, left >16.10 for male and right <11.20, left <10.65 for female) and Mid Shaft Diameter (right >1.33, left >1.38 for male and right <0.66 and left <0.67 for female) are important parameters to determine sex. Conclusions:The clavicle shows significant sexual dimorphism and bilateral asymmetry in Nepalese population. The result of this study is helpful to anthropologist and forensic medicine.

Introduction: Face has priority in identification of an individual. Nose occupying the middle of face is animportant sense organ that helps in respiration. Nose and face can be classified into different types accordingto nasal index and facial index. The aim of this study was to analyze nose and face type and find out itsdominance in different sex of Nepalese and Indian population. Methods: This was a quantitative observationalstudy conducted on 156 medical students using simple sampling method. Data were collected then nasalindex and facial index were calculated. Descriptive statistical data i.e. mean, standard deviation, togetherwith the independent-samples t-test results for anthropometric variables of nasal and facial parameters insex and Nationality (Nepalese and Indian) were analyzed. Results: All the measurement values were morein males compared to females, but the sexual dimorphism in nasal index (male 76.25 ± 7.75, female 75.70± 8.05) and facial index (male 85.77 ± 8.1, female 82.97 ± 7.63) is not statistically significant. Chi-squaretest revealed significant difference in face type among Nepalese and Indian population. Mesorrhine wasthe most common type of nose in both the population. Nepalese had commonly euryprosopic type of facewhile Indians had hypereuryprosopic type of face. Conclusion: Sexual dimorphism was not significant inboth nasal and facial parameters while type of face was helpful in differentiation of Nepalese and Indianpopulation.
