Results of Outpatient Gamma Knife Radiosurgery for Primary Therapy of Acoustic Neuromas

摘要: Stereotactic radiosurgery (SRS) has been recognized as a non-invasive alternative to surgery for the treatment of acoustic neuromas. Purpose current study was define impact outpatient gamma knife (GKS) patients with unilateral sporadic neuromas treated within ten years. Follow-up images were analyzed using tumor volume measurements. 219 by GKS primary therapy. Patients NF-2 tumors excluded. eligible up 10 size limit 12.5 cm3. The median follow time 6 years after rad iosurgery. local control rate high (97%). Cranial nerve morbidities comparably low. 10% developed hearing loss and one patient experienced transient facial neuropathy (0.5%). Transient trigeminal neuropath y in 12 (5%) found be dependent on before treatment. Outpatient is safe effective method selected vestibular schwannomas.
