Abstract

Background

For surgical treatment of the face, detailed surgical planning is necessary to avoid later unaesthetic results. Most of the studies in the literature concentrate on the ears’ anatomy during childhood and adolescence. Nearly no study evaluates the anatomy of ears of people aged 50 or older. It was our aim to measure and evaluate the ear’s anatomy in Caucasians between the ages of 21 and 65.

Methods

Three-dimensional scans of 240 volunteers were taken. The subjects were divided into groups of males and females and each of them into three groups by age (21–35, 36–50, 51–65). Landmarks were placed in these scans. Distances, relations and angles between them were recorded.

Results

The distance between the subaurale and superaurale significantly increases (p < 0.001) during the aging process in males and females. Also, the width of the ear, measured between the preaurale and postaurale, significantly increased (p = 0.007) with advancing age. When the length of the ear is divided into four parts by anatomical landmarks, it extended the most in the lower quadrant with increasing subject age.

Conclusion

The ear of Caucasians does not stop changing its shape during adulthood. Even after the body has stopped growing, the ear still does. With the measured values in this study, it should be possible for the surgeon to plan the operation in advance and achieve satisfactory aesthetic outcomes.
