Abstract | OBJECTIVE: STUDY DESIGN: Case report. SETTING: Tertiary referral center. PATIENT: A 49-year-old man was referred to the authors' department for bilateral total hearing loss subsequent to bacterial meningitis 2 years earlier. Pure tone audiometry, auditory brainstem response tests, and promontory tests did not reveal any cochlear activity. Computed tomography showed bilateral and totally ossified cochleae. Magnetic resonance imaging confirmed the diagnosis by showing no cochlear signal on T2-weighed images and ruled out brainstem and cerebellopontine angle abnormalities. INTERVENTION: MAIN OUTCOME MEASURES: Word and sentence recognition tests in sound-only and sound plus vision modes. RESULTS: No postoperative complication was observed. Twelve electrodes could be activated, and their tonotopy was defined. Nine other electrodes were inactivated because of an absence of auditory response (4 electrodes) or paresthesia (5 electrodes). At the last follow-up visit, 26 months after the implantation, 50% of disyllabic word scores and 60% of sentence scores were achieved using auditory brainstem implant sound only. These scores reached 80% and 93%, respectively, with lip-reading. CONCLUSION:
