BACKGROUND: India is a country with large population and a mixture of ethnicities with Indo-Aryan, Dravidian, and Mongoloid ethnicities largely located in the six zones of the country, predominantly in North, South, and Northeast zones, respectively. There is a possibility of differences in auricular features among them and such data may be useful in different fields. Hence, the morphometry and somatoscopy of auricles were studied in the Indian population from the six zones of India. MATERIALS AND METHODS: Measurements of auricles of the ear of 350 individuals from six zones of India were taken and somatoscopic variations were also recorded. RESULTS: Morphometric parameters showed no zone-wise difference except prominence of the ear, which was different in the West and Central zones. All morphometric parameters showed sexual dimorphism. There was positive correlation between “auricle length (AL) to auricle attachment/root (AR)” as well as “AL to face length (FL)”. Somatoscopic parameters showed no statistically significant zone-wise difference. Rolled helix, free ear lobes, and the presence of Darwin tubercle showed predominance in the population. CONCLUSION: Although the North, Northeast, and South zones of India are supposed to have predominance of particular ethnicities, the present study derived that these ethnicities do not reflect in zone-wise differences in most of the parameters. Strong positive correlation of AL to auricle root as well as to FL has practicability in various fields, especially in reconstructive surgeries or in forensic identification. Although West and Central zones showed the difference in auricle prominence, there is still a need for appropriate definition of a “prominent ear”.
