Preservation of Cranial Nerve Function Following Gamma Knife Radiosurgery for Benign Skull Base Meningiomas: Experience in 121 Patients with Follow-up of 5 to 9.8 Years

Introduction. Microsurgical excision with preservation of juxtaposed neurovascular structures is considered the treatment of choice for skull base meningiomas, but there exists a great controversy regarding surgical resectability, potential risk for subsequent postoperative Cranial Nerve Deficit (CND) and the role of adjuvant or adjunctive treatment options. In this study we evaluated the effect of Gamma Knife Radiosurgery (GKRS) in 121 patients with benign basal meningiomas after a follow-up of 5 to 9.8 years.
