Abstract

We report two cases of carotid-cochlea dehiscence involving the cochlear apex, with, to our knowledge, the first description of this anomaly in two members of a family (mother-daughter). Pure tone audiometry revealed a bilateral mild sensorineural hearing loss predominantly on the left in the daughter, and a left mild mixed hearing loss with a predominance of sensorineural loss in the medium frequencies in the mother Carotid-cochlear dehiscence is a rare anomaly with a multiform expression, which should be investigated in cases of third mobile window symptoms, but also atypical sensorineural hearing loss, or before any cochlear implantation.
