Linear Morphometric Analysis of Auricular Measurements of a Nigerian Igbo population

The human ear (auricle) is an important body component in biometric studies and forensic identification. purpose of this study was to evaluate linear auricular morphometric measurements a Nigerian Igbo population. 300 participants (142 males 158 females) at least 16 years age were randomly recruited from settlements the South-Eastern states Nigeria. made sit Frankfort horizontal position such as total height (TEH), width (EW), lobule (LH) (LW) obtained using digital vernier caliper (validated by calibrating 0.01mm). index (EI) (LI) calculated measurements. Data analyzed Statistical Package for Social Sciences (SPSS version 23.0). following mean values recorded males: TEH [Right (R) = 47.01±6.30, Left (L) 46.24±5.85], EW (R 25.06±4.14, L 24.68±4.32), LH 13.92±2.61, 13.99±2.18), LW 12.99±2.30, 13.30±1.94), EI 53.47±7.23, 53.28±6.69) LI 95.17±18.12, 96.80±18.56); females, 48.25±6.83, 48.25±6.24), 25.19±3.93, 24.57±4.21), 14.44±2.67, 14.89±2.55), 13.37±2.26, 13.78±2.04), 52.50±6.85, 50.93±7.05) 94.60±19.59, 94.30±16.63). Gender differences highly significant regarding height, lobular length width, well left auricle. This provides baseline data morphometrics adult Igbos could be used ergonomic guide towards creation hearing aids future solve possible issues associated with identification remains.
