OBJECTIVE: The aim of this study was to evaluate the hearing outcome of cochlear implantation in patients deafened by Ménière's disease.
STUDY DESIGN: Retrospective single-institution study.
SETTING: Tertiary medical center.
METHODS: Our institutional database of 1400 patients with cochlear implants was reviewed to identify cases with deafness due to Ménière's disease. Twenty-nine patients were identified: 24 with unilateral and 5 with sequential bilateral cochlear implants. Pre- and postoperative speech recognition scores and medical data were extracted from the medical record and analyzed.
RESULTS: Overall the mean difference between pre- and postoperative speech recognition after >1 year was 56% (95% CI, 47.08%-64.92%). The mean preoperative monosyllabic word score was 9.5%, and the mean postoperative scores at 1 month, 3 months, 6 months, 1 year, and >1 year were 37.1%, 46.1%, 54.1%, 59.1%, and 66.8%, respectively. Cochlear implantation resulted in improved word scores in all patients regardless of prior medical or surgical treatment (endolymphatic sac, labyrinthectomy). The mean postoperative hearing improvement in patients aged <70 and ≥70 years was 65.26% (95% CI, 54.79%-75.73%) and 40.00% (95% CI, 27.22%-52.77%). Postoperative word scores in patients with bilateral cochlear implants were not significantly different between the first and second implanted ears or between the monoaural and binaural testing conditions.
CONCLUSION: Cochlear implant in patients deafened by Ménière's disease significantly improves word recognition scores regardless of whether medical or surgical treatment is used prior to implantation. The potential improvement in word recognition scores decreases after age 70 years.
