Morphometry of the External Ear in Our Adult Population

Abstract

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.

Anthropometric Measurements of Human Ear Lobule in Adult Student Population

“…Sexual dimorphism is seen in the auricular linear dimensions with higher values in males. Brucker et al [5] observed an average LH to be 1.88cm and according to a study done by Bozkir et al [2] LH was 1.8 cm in young men and 1.7 cm in young women. Mc Kinney et al [15] obtained data from 100 volunteers and found a mean LH of 1.8 cm.…”

Determination of the limits of usability of auricle morphology for personnel identification

The shape of the ear gives information about age and sex, which is clear.…”

Asymmetry, Handedness and Auricle Morphometry

“…It can be perceived easily that structures of auricle convey signs of age and sex although not easily defined. They are important for the maintainence of a harmonious and pleasing appearance of the face (Brucker et al, 2003;Bozkir et al, 2006). In an anthropometric growth study of external ear in Canadian Caucasians, it was found that the auricle width and auricle length reached the mature size in males at 7 and 13 years and in females at 6 and 12 years; respectively (Farkas et al, 1992).…”

“…There were fine and detailed studies on morphometry of the auricle (Farkas et al;Ferrario et al, 1999;Brucker et al;Kalcioglu et al;Barut & Aktunc, 2006;Bozkir et al;Purkait & Singh, 2007) but studies investigating the asymmetry of auricle were very rare (Jung & Jung, 2003;Liu, 2008) and to our best knowledge there was only one study investigating the relation of auricle asymmetry and hand preference (Jung & Jung). The aims of this study were to determine various morphometric measurements of right and left auricles, to investigate asymmetry and its relation with handedness in both sexes.…”
