OBJECTIVE: Evaluation of the self-perceived hearing impairment and performance after cochlear implantation in patients with definite Menière's disease (MD).
PATIENTS AND METHODS: Seventeen unilaterally or bilaterally profoundly hearing-impaired patients suffering from MD who received a cochlear implantat (CI) were eligible for inclusion in this study. Their self-perceived hearing impairment using the short Speech Spatial and Qualities of Hearing Scale (SSQ12) as well as their performance in speech perception (German language Freiburger mono- and multisyllable test, Oldenburger sentence test) were compared with a best-matched control group of non-MD patients up to 24 months of follow-up.
RESULTS: MD patients improved significantly in perception of monosyllables presented at 65 dBSPL, from preoperatively best aided 18.2% [2.4, 34.0] to 51.7% [39.4, 63.9] 1 year after cochlear implantation (mean [95% confidence interval]). Their performance approached the matched controls with 63.2% [55.7, 70.8]. Monosyllables presented at a lower intensity of 55 dBSPL revealed a significant underperformance of the MD patients (21.1% [12.6, 29.6]) in contrast to the non-MD controls (39.1% [30.9, 47.4]) 12 months post-CI. Self-assessed hearing disability was significantly more pronounced in MD patients with a mean total SSQ12 score of 3.6 [2.4, 4.9] in comparison to 6.1 [5.4, 6.8] of the matched non-MD controls after 12 months of cochlear implantation.
CONCLUSION: Cochlear implantation substantially improves hearing capabilities in profoundly hearing-impaired patients with MD, but they tend to underperform in comparison to non-MD patients at least at lower sound pressure levels. This is likely one reason for the poorer self-assessed hearing function of cochlear implanted MD patients.
LEVEL OF EVIDENCE: 3, retrospective, nonrandomized follow-up study.
