Abstract

Introduction: Face has priority in identification of an individual. Nose occupying the middle of face is an
important sense organ that helps in respiration. Nose and face can be classified into different types according
to nasal index and facial index. The aim of this study was to analyze nose and face type and find out its
dominance in different sex of Nepalese and Indian population. Methods: This was a quantitative observational
study conducted on 156 medical students using simple sampling method. Data were collected then nasal
index and facial index were calculated. Descriptive statistical data i.e. mean, standard deviation, together
with the independent-samples t-test results for anthropometric variables of nasal and facial parameters in
sex and Nationality (Nepalese and Indian) were analyzed. Results: All the measurement values were more
in 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-square
test revealed significant difference in face type among Nepalese and Indian population. Mesorrhine was
the most common type of nose in both the population. Nepalese had commonly euryprosopic type of face
while Indians had hypereuryprosopic type of face. Conclusion: Sexual dimorphism was not significant in
both nasal and facial parameters while type of face was helpful in differentiation of Nepalese and Indian
population.
