title: [Supratentorial meningiomas. Diagnosis, surgical results and complications].
abstract: Meningiomas are benign tumors arisising from arachnoid cells and represent the commonest asymptomatic intracranial tumors. We analysed 69 supratentorial meningiomas managed by the Neurosurgical Tumor Group of the Clinics Hospital of Medicine School of São Paulo University (September 1995 to September 1997). Age, sex, edema degree, tumor site, surgical complications and mortality were studied. Edema degree was defined by radiological methods (CT and MRI). Forty-seven patients were women and average age was 58 years. Type II of edema degree was predominant (38.7%). Twenty-nine patients had parasagital meningiomas and 40 presented convexity tumors. Simpson I resection was obtained in 48 procedures, II in 18 and III in two surgical removals. Nine cases complicated (transitory deficits, 6; permanent deficit, 1; and infection, 2). Death occurred in two patients. Morbity and mortality had relation with age, falx tumors and attempt of radical surgical removal. Edema degree did not modify mortality and morbidity rates.
