Abstract

 

Different types of otic capsule dehiscence restricted to the cochlea have been described. Here we describe the case of a patient with a cochlear–internal auditory canal dehiscence associated with a cochlear–facial dehiscence not reported before. A 53-year-old patient with severe to profound sensorineural hearing loss due to bilateral Meniere’s disease underwent a cochlear implant surgery on the right ear. Preoperative brain magnetic resonance imaging findings were reported to be normal; during surgery, a cerebrospinal fluid gusher occurred at the time of round window opening. Postoperative computed tomography imaging showed a bony dehiscence at two levels of the otic capsule.
