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.
