This is an observational study for patients undergoing surgery to remove a vestibular schwannoma (a noncancerous brain tumor affecting hearing and balance) who also want to receive a cochlear implant to restore hearing. Researchers will use a special test called eABR (electrical auditory brainstem response) before, during, and after your surgery to measure how well your hearing nerve is working. They want to see if these nerve measurements can predict how well you'll hear with your new implant.
When surgeons remove a vestibular schwannoma, the hearing nerve can be damaged during the operation. Doctors need better ways to predict whether a patient will benefit from a cochlear implant after surgery. This study examines whether measuring nerve activity during surgery can help doctors understand and improve hearing outcomes for their patients.

Before your surgery, you will have a baseline nerve test (eABR) to measure your hearing nerve function. During your tumor removal surgery, doctors will perform the nerve test again to monitor your nerve during the procedure. After surgery heals, you will receive your cochlear implant as normally done. Several weeks or months later, your hearing will be tested using standard word recognition tests, and researchers will compare those results to your nerve measurements from surgery to see if there's a connection.
