“COMPARATIVE STUDY OF VARIOUS NASAL PARAMETERS AMONG NORTHERN AND SOUTHERN POPULATION OF INDIA”.

Abstract

Background: The shape of the nose is a signature indicating the ethnicity ,race, age, and sex. Anthropometric parameters vary with age, sex, and ethnic background, and several authors have attempted to document normative values which may serve as references. Materials and Methods: This study includes measurement of different parameters of nose among 14 North Indian(9 males;5 females) and 61 South Indian medical students (27 males;34 females) using vernier calliper and was statistically analysed. Results: The means of various parameters were- 1)Nasal Breadth -2.8cm (North Indians) and 2.7 cm(South Indians).2)Nasal height5.2cm(North Indians) and 4.9cm(South Indians).3)The nasofacial angle-39.4 degree(North Indians) and 37.2 degree(South Indians).4)The nasolabial angle is 118.2 degree(North Indians) and 115.9 degree(South Indians).5)The nasofrontal angle 129.3 degree(North Indians) and 131.3degree(South Indians).6).The most common type of nose is leptorrhine in both North and South Indians. Conclusion: All the measurements can be used for evaluation of nasal deformity, treatment planning and post surgical evaluation of the correction achieved during rhinoplasty.
