Simultaneous Labyrinthectomy and Cochlear Implantation for Patients with Single-Sided Meniere's Disease and Profound Sensorineural Hearing Loss

Objective. To investigate the treatment outcome of a simultaneous labyrinthectomy and cochlear implantation in patients with single-sided Meniere's disease and profound sensorineural hearing loss. Study Design. Prospective study. Method. Five patients with single-sided Meniere's disease with active vertigo and functional deafness were included. In all cases, simultaneous cochlear implantation combined with labyrinthectomy surgery was performed. The outcome has been evaluated by the Dizziness Handicap Inventory (DHI) and speech recognition. Results. The combined labyrinthectomy and cochlear implantation led in all patients to a highly significant reduction of dizziness up to a restitutio ad integrum. After activation of the cochlear implant and rehabilitation, a mean monosyllabic speech understanding of 69% at 65 dB was observed. Conclusion. For patients with single-sided Meniere's disease and profound sensorineural hearing loss the simultaneous labyrinthectomy and cochlear implantation are efficient method for the treatment of vertigo as well as the rehabilitation of the auditory system.
