Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults over 18 years old with vestibular schwannomas measuring between 10 and 25 mm in diameter.
✕Probably not a fit
Patients with vestibular schwannomas smaller than 10 mm or larger than 25 mm, or those with contraindications for nimodipine, will not benefit from this study.

What this trial studies
This study evaluates the effects of nimodipine, a medication known for its neuroprotective properties, when applied directly to the facial and cochlear nerves during the surgical removal of vestibular schwannomas. It is a prospective, randomized, placebo-controlled, double-blinded trial aimed at determining whether nimodipine can reduce the risk of postoperative facial paralysis and hearing loss. Participants will be randomly assigned to receive either nimodipine or a placebo during their surgery, with outcomes assessed postoperatively.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the incidence of facial paralysis and deafness in patients undergoing vestibular schwannoma resection.
How similar studies have gone: Previous studies have suggested positive effects of nimodipine on nerve function preservation, indicating potential success for this approach.
