OBJECTIVE: The aim of this study was to reveal the anthropometric growth of auricula from birth to the age of 18 years and to bring out the dynamics of ear growth. MATERIAL AND METHODS: A total of 1552 children in 50 groups were evaluated. Six surface measurements were performed directly on the right auricle of the subjects: the length from the superaurale to subaurale, the width from the tragus to helix, the width from the tragus to antihelix, the conchal depth, the height from the helix to mastoid at superauraler level, and the height from the helix to mastoid at tragal level. The frequency of prominent ear deformity and the degree of attachment of the lobule were also noted. RESULTS: Vertical auricular growth was complete in girls at the age of 11 and in boys at the age of 12, whereas the auricular width from the tragus to helix, the height from the helix to mastoid at superauraler level and the height from the helix to mastoid at tragal level were found almost complete at the age of 6. The auricular width from the tragus to antihelix attained its full size at 6 months for girls and 12 months for boys. The conchal depth was found almost complete at the age of 5 in both sexes. The incidence of prominent ear deformity and attached lobule was 9.8 and 26.5%, respectively. CONCLUSIONS: Different ear growth pattern and maturation size from previously published reports are obtained in different populations. There is still need for future studies comparing populations with different social and ethnic background to interpret common knowledge about the size of the ear. This study gives dimensional information and the growth pattern of the auricle, and therefore may reveal important implications for the adequate timing of the surgical treatment of auricular deformity.
