“…Few studies have investigated speech perception outcomes after cochlear implantation in MD; in general, outcomes are favorable and compare similarly to those reported in the non‐MD adult population 15–17 . Other studies have also investigated the use of cochlear implantation in MD concomitant with other surgical procedures for vertigo control 18–23 . However, to our knowledge, no study has reported acoustic hearing preservation outcomes after cochlear implantation in MD.…”

As the indications for cochlear implantation have expanded to include patients with greater degrees of residual hearing, this has relevance.…”

Objectives/Hypothesis: To evaluate speech perception outcomes and hearing preservation after cochlear implantation in patients with Meniere's disease (MD). Study Design: Retrospective chart review. Methods: Fifty-one adult patients, accounting for a total of 63 implants, with MD treated at a tertiary care center were included in the study. Patients with unaided preoperative air-conduction thresholds ≤80 dB at 250 Hz were included in hearing preservation analyses. The primary outcome measure was Consonant-Nucleus-Consonant (CNC) score. Hearing preservation was assessed as follows: 1) maintenance of functional hearing, defined as a postoperative unaided air-conduction threshold ≤80 dB at 250 Hz and 2) low-frequency pure-tone average (LFPTA) shift. Results: Speech perception scores improved significantly postimplantation; specifically, the CNC mean score was 9% preoperatively and increased to 57% by 1 year postoperatively (P < .001). Eighteen ears were included in hearing preservation analysis; the mean preoperative LFPTA was 65 dB (standard deviation [SD] = 10). The mean postoperative LFPTA at activation was 93 dB (SD = 21), and at 1 year was 102 dB (SD = 11). Twenty-seven percent of patients achieved short-term functional hearing preservation, whereas the longer-term outcomes were less favorable (11%). Conclusions: Speech perception scores improve after implantation in patients with MD. Hearing preservation is possible in patients with MD, albeit at lower rates than reported non-MD populations. Our data suggest that there can be degradation in acoustic hearing over time.

Objectives/Hypothesis: Meniere's disease (MD) is a debilitating condition characterized by hearing loss, vertigo, and tinnitus. The objective of this study was to systematically investigate outcomes in MD after cochlear implantation (CoI), with and without labyrinthectomy.Study Design: Systematic review and meta-analysis. Methods: A systematic review of articles in Medline and Embase was performed to identify all studies of patients with MD who underwent CoI. This analysis evaluates outcomes of speech recognition, pure tone audiometry, vertigo, tinnitus, and quality of life.Results: Of 321 studies identified, 37 were included, involving 216 patients. Mean age at implantation was 61.4 years (range 27-85 years) with average length of follow-up at 1.7 years (range 0-9 years). Forty-four (20.4%) patients underwent labyrinthectomy. Meta-analysis demonstrated significant improvements in audiometric outcomes following CoI. There was a statistically significant improvement in Hearing in Noise Test performance, with a mean difference improvement of 44.7 (95% confidence interval [CI] [8.8, 80.6]) at 6 months and 60.1 (95% CI [35.3, 85.0]) at 12 months. The Freiburger Monosyllabic Test (FMT) and Consonant-Nucleus-Consonant (CNC) also improved significantly, with mean difference improvements of 46.2 (95% CI [30.0, 62.4]) for FMT and 19.3 (95% CI [8.1, 30.4]) for CNC. There was a statistically significant decrease in tinnitus, as measured by a mean difference reduction of 48.1 (95% CI [1.0, 95.2]) in the Tinnitus Handicap Index.Conclusions: CoI with and without simultaneous labyrinthectomy is a viable treatment option for patients with MD, yielding high rates of tinnitus suppression and vertigo control. Post-CoI MD patients demonstrate similar postoperative speech perception outcomes to non-MD implant recipients.

“…Radiological: Magnetic Resonance Imaging (MRI) should be done to exclude retrocochlear pathology especially in unilateral MD with asymmetric sensorineural hearing loss; MRI also is beneficial in evaluating cochlear nerve integrity especially in patients who had undergone vestibular nerve section. Finally, MRI could provide us with some information regarding cochlear ossification or fibrosis together with Computerized Tomography (CT) [15].…”

Meniere's disease is a chronic inner ear disease characterized by fluctuating sensorineural hearing loss, recurrent vertiginous attacks, tinnitus with aural fullness. Whether hearing loss is secondary to natural progressive course of disease or due to interventions, noticeable number of patients with Meniere's disease has unilateral non-serviceable hearing. So, cochlear implantation provides hope for those patients not only for hearing rehabilitation but also its positive effect on other non-auditory symptoms of Meniere's disease. Our article aims to review the beneficial effects of implanting patients with Meniere's disease regarding their hearing gain as measured by standard audiometric testing and discuss the effect of implantation on auditory and vestibular outcomes.
