Cochlear Implantation After Gamma Knife Radiosurgery with EABR and Correlation to Postoperative Hearing Results - a Pilot Study
This study examines patients who receive cochlear implants (hearing devices) after having radiation treatment for a vestibular schwannoma (a non-cancerous tumor on the hearing nerve). Researchers will measure electrical signals in the ear before and during implant surgery to better understand how the radiation affects the implant's success.
Key Objective: This trial tests whether measuring electrical signals during cochlear implant surgery can predict how well patients will hear after the procedure.
Who to Consider: Patients who have previously undergone gamma knife radiation for vestibular schwannoma and are now candidates for cochlear implantation should consider enrolling.
Trial Parameters
Brief Summary
Patients undergoing cochlear implantation after radio surgery for vestibular schwannoma will be included in the study. Patients will undergo preoperative and intraoperative eABR measurement. Correlations to postoperative hearing results will be drawn.
Eligibility Criteria
Inclusion Criteria: * Patients who have undergone radio surgery for vestibular schwannoma * Patients wanting cochlear implantation for hearing rehabilitation Exclusion Criteria: * Patients not wanting to participate in the study
