著者在过去16年中曾为95例(男61,女34;单耳74,双耳21)中的113耳做了耳畸形成形术。这些患者的母亲妊娠时无严重疾病,2例有耳畸形家族史。先天性耳畸形可分为四型: Ⅰ型(1):耳廓比正常位置向前向下,外耳道骨与软骨接合处呈“拱形”狭窄。Ⅰ型(2):耳廓移位向下更甚;外耳道缺如;在相当于外耳道中1/3处有时可探到较大气房;鼓膜可能是骨板;锤骨砧骨往往畸形;砧骨与镫骨头经常相互连接。 The author has performed otoplasty on 113 of the 95 cases (male 61, female 34; monaural 74, both ears 21) for the past 16 years. The mothers of these patients had no serious disease during pregnancy and two had a family history of ear malformations. Congenital malformations can be divided into four types: type (1): the auricle than the normal position forward and downward, the external auditory canal and cartilage junction was “arch” stenosis. Ⅰ type (2): auricle shift even more down; lack of external auditory meatus; in the equivalent of 1/3 of the external auditory meatus can sometimes explore the larger room; tympanic membrane may be bone plate; tendon deformity tendon; anvil Bones and bones are often interconnected.
