Morphometry of the External Ear in Our Adult Population

This study aimed to determine the mean values of the different morphometric measurements from right and left ears. These measurements were taken from 341 healthy young adults (150 women and 191 men) ages 18 to 25 years using an electronic digital caliper. The results showed the mean values for total ear height, lobular height and width, distances from tragus to antihelix and to helix, and ear projection and width to be, respectively, 59.7 ± 3 mm, 17.5 ± 1.4 mm, 18.5 ± 2.2 mm, 16.6 ± 1.7 mm, 25.1 ± 2 mm, 16.6 ± 2 mm, and 31.3 ± 2.2 mm for the left ear, and 59.5 ± 3.1 mm, 17.9 ± 1.5 mm, 18.9 ± 2 mm, 16.5 ± 1.8 mm, 25.2 ± 1.9 mm, 17 ± 1.9 mm, and 31.2 ± 2.2 mm for the right ear in the young women. However, in the young men, these values were, respectively, 63.1 ± 3.6 mm, 18.3 ± 1.7 mm, 19.4 ± 2 mm, 17.2 ± 1.8 mm, 26.3 ± 1.9 mm, 17 ± 2.3 mm, and 33.3 ± 2.2 mm for the left ear, and 62.9 ± 3.5 mm, 18.4 ± 1.7 mm, 19.8 ± 1.9 mm, 17.2 ± 1.8 mm, 26.6 ± 1.9 mm, 17.6 ± 2.1 mm, and 33.1 ± 2.1 mm for the right ear.
