Patients with vestibular schwannomas have several treatment options now days. For patients with small or medium-sized tumors, stereotactic radiosurgery has become a common noninvasive treatment modality. The present study included 24 patients with vestibular schwannomas who underwent stereotactic radiosurgery at Kasr EL Ainy center of radiation oncology (NEMROCK), in collaboration with the Neurosurgical department, during the period between February 2001and February 2003. All patients were followed up to a mean period of 15 months +/- 7. Effect of radiosurgery on the tumor growth control rate, 7th and 8th cranial nerves, was assessed and results were analyzed in an attempt to evaluate the effectiveness of this treatment modality in vestibular schwannoma patients. The over all results showed a tumor growth control rate of 83.33%, facial nerve function preservation of 75%, and hearing preservation of 59.09%.
