Abstract

Congenital stapes superstructure fixation was found in a mother in both ears and her daughter in one ear. The head of the stapes was fixed to the pyramid by a bony bar which lay immediately superior to a normal stapedius muscle. Removal of the bony bar resulted in normal hearing, which has been maintained. We believe that these are the first reported cases of this abnormality.

摘要

在一位母亲的双耳以及她女儿的单耳中发现了先天性镫骨上部结构固定。镫骨头通过一根骨棒固定于锥隆起，该骨棒紧邻正常的镫骨肌上方。去除骨棒后听力恢复正常，且一直保持。我们认为这些是该异常情况的首例报道病例。
