Morphometric Measurements of Human External Ear in student Population
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 6
Abstract
Introduction: In the adult the ear forms one anatomic unit serving both hearing and equilibrium. The external ear consists of pinna and external auditory canal concerned with hearing. Morphometric study of the external ear is of importance to physical anthropologists, physicians, forensic scientists and plastic surgeons. This study aimed to determine the mean values of different morphometric measurements from the left and right ears in the study population. Aim: To study the morphometric variations of pinna among students Methods: Measurements were taken from 384 healthy medical students aged 17 – 20 years using a standard vernier callipers. The parameters measured were total ear height (TEH), ear width (EW). Results: In our study we found that ear height and ear width values were more in right ears than left ears. All parameter values were more in males than females and their difference was statistically significant. Discussion: Knowledge of normal ear dimensions is important in the diagnosis of congenital malformations and acquired deformities and in the planning of treatment. It is also helpful in hearing instrument industry and forensic criminology. We believe the data presented in this study have yielded parameters for ear morphology that will prove useful in determining ear anomalies and variations, and may help the clinician to reproduce an anatomically correct ear during its reconstruction.
