Gamma Knife surgery for nonvestibular schwannomas: radiological and clinical outcomes

摘要: Object Most intracranial schwannomas arise from cranial nerve (CN) VIII. Stereotactic radiosurgery is a mainstay of treatment for vestibular schwannomas. Intracranial arising other CNs are much less common. We evaluate the efficacy Gamma Knife surgery on nonvestibular including trigeminal, hypoglossal, abducent, facial, trochlear, oculomotor, glossopharyngeal, and jugular foramen tumors. Methods Thirty-six patients with were treated at University Virginia center 1989 to 2008. The median patient age was 48 years (mean 45.6 years, range 10–72 years). Schwannomas arose following CNs: CN III (in 1 patient), IV 1), V 25), VI 2), VII IX XII 3). In 2 patients, tumors foramen. tumor volume 2.9 cm3 3.3 cm3, 0.07–8.8 cm3). margin dose 13.5 Gy (range 9.3–20 Gy); maximum 30 21.7–50...
