Abstract

The ear has been enlisted as a biometric identifiers that could be deployed to tackle security issues for national development, authentication, identification, storage and privacy of information. This study was aimed at photoanthropometrically determining auricular parameters, prevalence of pendulous earlobe, non pendulous earlobe, Darwin’s tubercle, sexual dimorphism and bilateral asymmetry in pinna of Yorubas and Igbos. 400 subjects (10-30 years) comprising 200 Igbo and 200 Yorubas were selected using simple random sampling technique. Total Ear Length (TEL), Total Ear Width (TEW), Tragus-Anti Helix (TAH), Tragus-Anti Tragus (TAT) was measured, prevalent earlobe types was analyzed and sexual dimorphism of the measured parameters was investigated. The result indicates significant difference in the different morphometric parameters of ears in relation to sex (P<0.05), males were observed to have higher TEL, TEW, TAH ear parameters than females, (P<0.05) in the right and left ear of both tribes. Bilateral asymmetry was also observed in mean TAH values which was consistently higher on the right than the left ear side of males and females of both tribes. Tragus-Anti Tragus (TAT) was observed to have higher mean values in females than males in the right and left ears. Findings from this study show that ear parameters show sexual dimorphism, bilateral asymmetry and show significant correlation with anthropometric variables such as age, height and weight hence can be used as predictors to form regression formula for biometric identification, predictions to aid biological profiling, facial recognition from security cameras and planning of cosmetic surgery.
