초록
When vestibular schwannoma originates from the segment within the labyrinth of the vestibulocochlearnerve, it is termed intralabyrinthine schwannoma (ILS). As most of the cases arepresented with profound sensorineural hearing loss on the affected side, for auditory rehabilitation,cochlear implantation can be considered simultaneously as the tumor removal. Successfulresults of cochlear implantation were reported in patients with ILS even after partialresection of the mass. In this study, we report the cases of two patients with ILS with unilateraldeafness. In one patient, a mass found in the basal turn of cochlea was removed totally anda cochlear implantation electrode was fully inserted. In the other patient, a mass found in thebasal turn and vestibule was partially removed and an electrode was inserted. Postoperatively,hearing was improved and tinnitus was reduced.
Abstract
When vestibular schwannoma originates from the segment within the labyrinth of the vestibulocochlearnerve, it is termed intralabyrinthine schwannoma (ILS). As most of the cases arepresented with profound sensorineural hearing loss on the affected side, for auditory rehabilitation,cochlear implantation can be considered simultaneously as the tumor removal. Successfulresults of cochlear implantation were reported in patients with ILS even after partialresection of the mass. In this study, we report the cases of two patients with ILS with unilateraldeafness. In one patient, a mass found in the basal turn of cochlea was removed totally anda cochlear implantation electrode was fully inserted. In the other patient, a mass found in thebasal turn and vestibule was partially removed and an electrode was inserted. Postoperatively,hearing was improved and tinnitus was reduced.
