An aberrant internal carotid artery in a young woman complaining of pulsatile tinnitus and conductive hearing loss was diagnosed pre-operatively by CT scan and angiographic findings. An exploratory tympanotomy was performed in order to evaluate the cause of the severe conductive hearing loss. It was possible to detect a large persistent stapedial artery associated with a stapedial fixation of unknown cause. Despite these vascular anomalies a stapedotomy was performed successfully.
一名年轻女性因搏动性耳鸣和传导性听力损失前来就诊，术前通过CT扫描和血管造影结果诊断出存在异常颈内动脉。为评估严重传导性听力损失的原因，进行了探查性鼓室切开术。术中发现一条粗大的永存镫骨动脉，伴有原因不明的镫骨固定。尽管存在这些血管异常情况，镫骨切除术仍成功实施。
