Hearing Treatment In Patients With Questionable Cochlear Nerve Functionality

摘要

An intraoperative approach for objective determination of auditory nerve functioning is described. Following surgical removal of tumor tissue impairing auditory functioning of a patient, an electrode array having electrode contacts is intra-operatively inserted into the cochlea of the patient. A diagnostic stimulation signal is provided to the electrode contacts to stimulate auditory nerve tissue within the cochlea. And an electrically evoked functional response is measured of the auditory nerve tissue to the stimulation signal.
