Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients who have had radiosurgery for vestibular schwannoma and are seeking cochlear implantation for hearing restoration.
✕Probably not a fit
Patients who do not wish to participate in the study will not benefit from its findings.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This study involves patients who have received gamma knife radiosurgery for vestibular schwannoma and are experiencing hearing loss. Participants will undergo extensive audiometric testing and preoperative and intraoperative electrically evoked auditory brainstem response (eABR) measurements. The study aims to correlate these eABR results with postoperative hearing outcomes following cochlear implantation. The findings will help assess the feasibility and effectiveness of cochlear implants in this patient population.
Why it matters
Potential benefit: If successful, this study could improve hearing rehabilitation options for patients with vestibular schwannoma who have undergone radiosurgery.
How similar studies have gone: While there may be related studies, this specific approach combining eABR with cochlear implantation post-radiosurgery is relatively novel.
