Cochlear implantation after labyrinthectomy.
OBJECTIVE
The goal was to report a method used for intraoperative ear selection for cochlear implantation using electrical brainstem response. Initial patient response and the longer-term results of cochlear implantation after labyrinthectomy were compared.


METHODS
This was a specific retrospective review of a single case of cochlear implantation after labyrinthectomy.


METHODS
The study involved a tertiary referral center in both an ambulatory and a hospital setting.


METHODS
The study involved a report of a single patient who was evaluated for a possible cochlear implant and successfully underwent cochlear implantation.


METHODS
A case study of a profoundly deaf individual is presented, including the diagnostic measures used to determine the candidacy for cochlear implantation, the ear selected, and the rehabilitation.


METHODS
Both early (3 months) and later (14 months) postoperative results clearly demonstrate that a cochlear implant in a patient with a previous labyrinthectomy can be beneficial.


RESULTS
The early and later results after cochlear implantation are compared in a single case study.


CONCLUSIONS
This case study demonstrates that there is improvement in sound awareness, speech recognition, and communication after cochlear implantation in a previously labyrinthectomized ear.
