Auditory Brainstem Implant in Adult Patient With Cochlear Ossification From Otosclerosis.

OBJECTIVE

The objective is to describe auditory brainstem implantation in a case of extensive cochlear otosclerosis.

PATIENT, INTERVENTION, AND

RESULTS

A case is presented of a 65-year-old male with bilateral cochlear otosclerosis and profound sensorineural hearing loss. Imaging studies showed distorted cochlear anatomy bilaterally and ossification of cochlear ducts. He underwent successful placement of an auditory brainstem implant using a retrosigmoid craniotomy approach.

CONCLUSIONS

Extensive cochlear otosclerosis may distort cochlear anatomy such that cochlear implantation is expected to have a poor outcome. Auditory brainstem implantation may be an additional treatment option in these patients.
