Background: The auricle is a complex part of the sensory organ, and is made of cartilage that is covered with skin. Its function is to capture sound. This study was aimed at knowing the auricular dimensions in Okrika tribe in Rivers state. Methods: Auricular parameters from 401 Okrika indigens from 18 years and above were measured using standard Vernier calliper. The Parameters were ear height (EH), ear width (EW), lobular height (LH) and the lobular width (LW) for both right and left ears with the head of the subject in Frankfort horizontal plane. Results: Data was analyzed using SPSS version 23.0. All the measured parameters were higher in males compared to females in both left and right ears, implying sexual dimorphism. The mean values of all measured parameters in males were higher on the right compared to the left. Except ear index (T = 0.83; P = 0.41), side differences were observed in all other parameters at P < 0.05. Hence auricular parameters are said to be asymmetrical. In females, the mean values of all measured parameters were higher on the right compared to the left. Except ear index (T = 0.95; P = 0.34) and lobular index (T = 1.30; P = 0.19), side differences were observed in all other parameters at P < 0.05. Conclusion: In this study, we observed that all measured parameters were higher in the right ear than in the left and also larger in males than females. This sex related differences were said to be sexually dimorphic. Therefore this study has provided anthropometric data for the okrika tribe, which will be useful in forensic science and ear reconstructive surgeries.
