title: Cochlear implantation in delayed sudden hearing loss after conservative vestibular schwannoma surgery.
abstract: This is a case of successful cochlear implantation in a 50-year-old man who experienced sudden hearing loss and developed ipsilateral severe tinnitus at three years following conservative stage 1 vestibular schwannoma retrosigmoid surgery. After cochlear implantation, tinnitus improved from THI grade 4 to 2. Localisation skills improved. Hearing in noise (S/N + 7 dB) with target signal from the operated side improved from 38 to 100% of correct answers. A significant improvement of spatial and speech items of the "speech, spatial and qualities of sounds" questionnaire was also measured. In conclusion, cochlear implantation is a feasible and effective solution after conservative vestibular schwannoma surgery should delayed hearing loss occur.
