Objective:
To describe a unique case of excellent audiometric outcomes for a prelingually deafened adult after cochlear implantation and to caution on the limits of magnetic resonance imaging for a diagnosis of cochlear nerve aplasia.
Patient:
Adult man with congenital bilateral profound sensorineural hearing loss.
Intervention (S):
Cochlear implantation.
Main Outcome Measure(S):
Audiometric testing and subjective hearing improvement.
Results:
Improved subjective and objective hearing after cochlear implantation.
Conclusions:
Consideration of cochlear implantation is reasonable for adults with long-standing hearing loss when preoperative audiometric testing is discordant with magnetic resonance imaging findings of radiographic cochlear nerve aplasia.
