Abstract
External ear morphometry is increasingly explored for forensic identification because ear dimensions show population variation and sexual dimorphism, requiring region-specific reference data. A cross-sectional study was conducted on 200 Central Indian adults (18-30 years) to assess external ear morphometry, morphology and sexual dimorphism and to explore relevance for identification purposes. Bilateral ear and lobular measurements were taken using a digital Vernier caliper and stature/weight was recorded using standard instruments. Males had significantly higher mean stature and weight than females. Ear length, ear width and lobule width were significantly greater in males on both sides, while ear index, lobule height and lobule index did not differ significantly by sex; oval ear shape predominated and Darwin’s tubercle showed a significant sex difference only on the right side.
