[COCHLEAR IMPLANTATION FOR PATIENTS WITH CONSERVATIVELY TREATED VESTIBULAR SCHWANNOMA].

Abstract

Introduction: Vestibular Schwannoma, a benign slow growing tumor on the eight cranial nerve, will eventually cause in most patients, a severe sensory neural hearing loss in the ipsilateral ear. Patients with asymmetric hearing loss experience difficulties in hearing in the presence of noise, in sound localization and an increase in listening effort, especially if contralateral hearing loss exists. Cochlear implant is the treatment of choice for hearing rehabilitation in severe to profound sensorineural hearing loss. This treatment was shown to be effective in patients with vestibular schwannoma whether they were treated by surgery, radiation or conservative surveillance only. In this case report we present 2 patients with stable growth of over 10 years, who presented with a severe decrease in hearing loss on the ipsilateral side and a known contralateral moderate loss. Both underwent cochlear implant with no other intervention and demonstrated great speech perception results and continue to use the implant regularly for several years. The cochlear implant is an effective tool for hearing rehabilitation for patients with a stable vestibular schwannoma under conservative surveillance. It is of grave importance to properly educate these patients on hearing rehabilitation and recommend cochlear implant for appropriate patients.
