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.
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.
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.
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.
本研究旨在揭示耳廓从出生到18岁的人体测量生长情况，并阐明耳部生长的动态变化。
对50组共1552名儿童进行了评估。直接对受试者的右耳廓进行六项表面测量：耳上点至耳下点的长度、耳屏至耳轮的宽度、耳屏至对耳轮的宽度、耳甲深度、耳上点水平耳轮至乳突的高度以及耳屏水平耳轮至乳突的高度。同时记录招风耳畸形的发生率和耳垂附着程度。
女孩在11岁时耳廓垂直生长完成，男孩在12岁时完成；而耳屏至耳轮的宽度、耳上点水平耳轮至乳突的高度以及耳屏水平耳轮至乳突的高度在6岁时几乎已完成生长。耳屏至对耳轮的宽度女孩在6个月时达到其最大尺寸，男孩在12个月时达到。耳甲深度在两性中5岁时几乎已完成生长。招风耳畸形和附着耳垂的发生率分别为9.8%和26.5%。
不同人群的耳部生长模式和成熟尺寸与先前发表的报告不同。仍需要未来的研究比较具有不同社会和种族背景的人群，以解读关于耳朵大小的常识。本研究给出了耳廓的尺寸信息和生长模式，因此可能揭示对耳部畸形手术治疗合适时机的重要启示。
