The exact pathomechanism of deafening in Meniere's disease (MD) is still unknown; intoxication of hair cells and neural damage from endolymphatic hydrops is discussed. In the literature, there are only a few reports on hearing outcome of MD patients after treatment with cochlear implantation (CI) whereby especially the comparison of MD vs. non-MD patients with CI differs. In this retrospective study, results in speech understanding [Freiburger Einsilber (FES65) and Hochmair-Schulz-Moser test in quiet (HSM) and in noise (HSM + 10 dB)] of 27 implanted MD patients were collected and compared to a matched standard CI cohort. Alternative diagnoses were excluded as far as possible by re-analyzing neuroradiologic imaging. After first fitting, MD patients showed significantly better results in FES and HSM testing compared to controls. At 1-year refitting, this effect could not be seen anymore. To conclude, cochlear implantation is a safe and effective treatment for deafness in MD patients. Results in speech understanding are at least equal compared to general CI recipients. To the best of our knowledge, this retrospective study examined the largest collective of CI users deafened by MD so far.
