Intracranial meningiomas (ICMs) may be diagnosed in octogenarians. Since the lesions are rarely life-threatening, surgery is a questionable choice in this age group. The authors' aim in this study was to analyze factors associated with the extent of resection (EOR), overall survival (OS), and postoperative complications in octogenarians undergoing ICM surgery, by using a cohort of septuagenarians as a reference.
