For patients who present with bilateral severe-to-profound sensorineural hearing loss who have little-to-no benefit from conventional hearing aids, cochlear implants can restore hearing by directly stimulating the cochlear nerve. A standard mastoidectomy and facial recess approach is performed to visualize the round window niche and membrane. The round window membrane is opened, and the cochlear implant electrode is carefully inserted into the scala tympani. After several weeks, the patient returns for implant activation with a dedicated team of audiologists.
