Cochlear implantation after microsurgical resection of intralabyrinthine schwannomas has shown promising results in a limited number of small studies with safe and favorable outcomes. Cochlear implantation is a mainstream treatment for advanced bilateral sensorineural hearing loss and, more recently, has been applied to patients with single-sided deafness.The case presented is a 66-year-old gentleman with a history of progressive right-sided sensorineural hearing loss and bothersome tinnitus with a right intralabyrinthine schwannoma involving the semicircular canals, vestibule, and basal turn of the cochlea. The authors describe concomitant cochlear implantation after microsurgical resection of an intralabyrinthine schwannoma. Intralabyrinthine schwannomas represent an uncommon subtype of benign tumors arising from the terminal branches of the vestibulocochlear nerve. Symptoms often include sensorineural hearing loss, dizziness, and tinnitus, and in this location, symptoms often arise at a small tumor size. In this featured case, we present a patient who underwent gross total tumor resection and cochlear implantation for hearing rehabilitation and treatment of tinnitus. Six months after surgery, the patient achieved good device performance, scoring 46% on consonant-nucleus-consonant word testing and 66% on AzBio sentence testing, and subjective improvement in his tinnitus. |
