Patients treated with radio surgery for vestibular schwannoma often suffer from hearing loss. Especially when the contralateral side has progressive hearing loss assessment if cochlear implantation is feasible, should be carried out. Patients undergo extensive audiometric testing. Additionally, patients will undergo preoperative eABR. Intraoperatively eABR is carried out and cochlear implantation is performed. The eABR results will be correlated with postoperative hearing. EABR measurements are not part of the study. The results of eBAR will be categorized in three groups (good response, weak response and no response). The eABR results will then be correlated to speech understanding with cochlear implants measured with Freiburger monosyllables test.
