Abstract

Introduction: Darwinian tubercle is a congenital ear structure which often presents as a thickening in the helix at the junction of the upper and middle third of the outer ear. This cross-sectional study considered the prevalence of auricular tubercle among Ika people in Delta State, Nigeria. Materials and Methods: Ethical clearance was gotten from the Ethical Board of Human Anatomy Department, Delta State University, Abraka in Nigeria. The data were sorted by means of the Statistical Package for the Social Sciences (SPSS), version 25.0. This study made use of 388 subjects and informed consent was obtained from the volunteer subjects before commencement of the study. Results: The most common auricular tubercle congenital association was accessory tragus, followed by weathering nodules, and congenital absence of the helix. Bilateral asymmetry exists as regards the shape of the ear. Auricle shape varied with the left and right sides as well as sexes. The Darwin tubercle displayed significant gender difference in auricular prevalence (p<0.05), and there was no significant age difference in auricular prevalence (p>0.05). Conclusion: The prevalence of auricular tubercle in this study is forty-nine percent. The most common auricular tubercle congenital association is accessory tragus.
