Nose is one of the most important structures of the face in terms of facial aesthetics. Population based cross-sectional study was carried out on 600 adults of three different endogamous groups (Brahmin-200, Majhabi-Sikh-200 and Muslim-200) inhabiting Punjab. Four nasal parameters were measured for each selected individual and nasal index was calculated. Sexual dimorphism was recorded in all parameters except for nasal depth among Muslims. The parameters showed significant differences between three groups (p<0.001) and clearly showed the anthropometric variation for nasal parameters in three communities. Therefore, it can be suggested that nasal parameters can play significant role in determining sex and ethnicity of characteristic pure races of national importance and the plastic surgeons can utilize this knowledge during rhinoplasty of an individual from a particular endogamous group.
