Observational studies
11 total studies; 6 included in the pooled-analysis
For patients with Meniere's disease who receive a cochlear implant (CI), pooled analysis across five studies found improved tinnitus perception, ranging from attenuation to complete absence of symptoms; however, large variability was demonstrated among studies. Additional research is warranted.
For patients with Meniere's disease, pooled analysis across studies investigating cochlear implantation (CI) was unable to find a consistent outcome for vestibular impairment. Comparison of pre-CI versus post-CI vestibular characteristics was lacking. No definitive conclusions can be drawn and additional research is warranted.
For patients with Meniere's disease, pooled analysis across studies found that cochlear implantation (CI) demonstrated improved word recognition outcomes similar to other adult, post-verbal CI recipients. Patients with MD who receive a CI also show improvements or control of hearing fluctuation. "No definite conclusions can be drawn on residual hearing preservation or on the effects of bimodal stimulation" (p. 412). Further investigation of the effects of CI on hearing preservation is warranted.
