A comparative study on nasal ergonomics of Madhya Pradesh & Uttar Pradesh males

Abstract

IntroductionNasal index is an ethnic sensitive anthropometric index. It is an important anthropometric parameter for classifying the race and sex of an individual whose identity is unknown. The present study was undertaken to observe the midline nasal ergonomics of MP & UP males. Materials and MethodA random sample of males of 18–28 years age group was chosen for examination. Nasal breadth (NB), nasal height (NH) and nasal depth (ND) were measured with the help of Digital Vernier Caliper. Nasal index (NI) and nasal elevation index (NEI) of each group were calculated as NB/NH × 100 & ND/NB × 100. ResultThe result was analyzed statistically using Unpaired Student t-test with significant relationship (p < 0.001) of NI & NEI between the two groups. The result showed that the MP males had mean NI of 68.73 ± 8.25 while that of UP males had NI of 76.91 ± 6.25 (p < 0.001). DiscussionThe NI of MP males is <70 and so fall within the classification leptorrhine while the UP males had a NI between 70.00 and 84.9 so fall within the mesorrhine nose type. The NEI of MP males is 51.08 ± 7.33 which was greater than UP males which had 44.13 ± 6.54 which indicates that MP males have a significance protruded longer & more elevated nose than UP counterpart. The data obtained showed difference in nose types. Thus the data of this study is recommended in anthropological studies and reconstructive surgery amongst the ethnic groups under study.
