Abstract
Background: Nasal parameters are important in anthropology to distinguish race, sex and ethnic of people groups and are useful to identify unknown person. The aim of this study was to determine the anthropometric characteristics of Nose in residents of Qazvin, Iran. Materials and methods: A cross-sectional survey was performed on 300 adults from Qazvin; they were 18 to 55 years-old. There were 160 males and 140 females with a male/female ratio of 1.2:1.This group was randomly selected. Without gender prejudices their nasal parameters, nasal height, tip protrusion and alar thickness, were measured using a sliding caliper. Results: The mean nasal width/height (Nasal index -NI) was 90.7 in males and 88.2 in females. Males had a higher NI compared to females (p < 0.03). The most common type of nasal variability is type A (70.5%), Platyrrhine nose, Type B (26.7%) especially in females (mesorrhine) and Type C (leptorrhine) (2.8%). Conclusion: There is a significant correlation between sex of an individual and type of nose. Platyrrhine nose, among males and mesorrhine among females were more common, only 2.8% being leptorrhine. The nasal indices in males were higher than in females.
