Meningiomas of the anterior cranial fossa floor. Review of 67 cases.
The authors report 67 cases of meningioma of the anterior cranial fossa floor treated surgically between 1978 and 1992. The olfactory groove and tuberculum sellae were the most frequent locations. Mean duration of the clinical history was 30 months. Seventy-three percent of the tumors were large (> 4 cm). All patients were examined with computed tomography and 18 with magnetic resonance imaging as well. Complete removal was performed in 56 cases (84%); in the remaining 11 (16%), partial removal was performed because of encasement of the carotid artery, cavernous sinus, or optic nerves by the tumour. Mortality was 9%. Results at follow-up of the 61 survivors were good in 56 (84%), fair in four (6%), and poor in one (1%). The clinical results were correlated to tumor location and dimension. After review of the literature, the management of these difficult tumours and the preferred surgical technique are discussed. The authors stress the importance of early diagnosis for improving the surgical results.
