A case of unilateral conductive deafness since birth is described. At exploration of the middle ear, the facial nerve was found to have an anomalous course across the oval window region, the stapedial crura ending on the uncovered facial nerve. This case is believed to represent the 9th case to be recorded. This anomaly may be due to failure of union between the branchial part and otic capsule part of the stapes, in combination with a defective development of the laterohyale resulting in a partially absent facial canal.
本文描述了一例自出生以来即患有单侧传导性耳聋的病例。在中耳探查时，发现面神经在卵圆窗区域走行异常，镫骨脚末端止于裸露的面神经上。此病例据信是有记录以来的第9例。这种异常情况可能是由于镫骨的鳃部和耳囊部未融合，再加上外侧舌骨发育不全导致面神经管部分缺失所致。
