Official Title: Gamma Knife Radiosurgery vs Initial Conservative Treatment for Vestibular Schwannoma Patients With Preserved Hearing, a Prospective Randomized Study

Study ID: NCT01938677

Conditions

Vestibular Schwannoma

Interventions

Initial Gamma knife radiosurgery

Study Description

Brief Summary: The effect of Gamma knife radiosurgery (GKRS) on hearing loss, in patients with vestibular schwannoma (VS) and preserved hearing is still unclear. Retrospective data indicate that the hearing is preserved in most patient years after the gamma knife treatment. Recent prospective data suggests that radiosurgery could be a hearing preserving treatment for these patients. The main objective of this study is to evaluate if GKRS can inhibit progression of hearing loss in patients with VS. Patients with preserved hearing will be offered to participate in the study and randomized ether to GKRS or initial conservative treatment for their vestibular schwannoma. They will then be followed with scheduled magnetic resonance image(MRI) and audiometry and evaluated after one, three and five years after treatment.
