Abstract

Decision making in patients with a vestibular schwannoma (VS) in the only hearing ear is challenging. Restoration of hearing when they become deaf will depend on the status of the remaining cochlear and the integrity and function of the cochlear nerve. In terms of hearing restoration, cochlear implantation (CI) is the most effective option if the cochlear nerve could be preserved intact and the cochlea could be remained responsive to electrical stimulation. Auditory Brainstem Implantation (ABI) would be another option for the patients in which the cochlear nerve could not be spared during VS removal, while the hearing results with ABI are still far poor than those with CI. If CI is being considered, it should be performed near the time of the surgery for VS removal, because cochlear fibrosis and/or ossification might occur in a short time after the surgery. When the translabyrinthine surgery (TLS) for VS removal is selected, CI surgery should be completed as close as possible to the procedure. Simultaneous CI with TLS removal of VS was considered for the patient who suffered from a severe sensorineural hearing loss on the same side with VS and a profound deafness on the opposite side due to the past idiopathic sudden deafness. The first CI was preceded on the opposite side, and the second CI was performed on the tumor side one year after. Simultaneous CI with TLS VS removal is a good option that should be considered when discussing and planning the most appropriate strategy.
