Microsurgical removal of ambi-growing meningiomas in the falx cerebri and sagittal sinuses through Interhemispheric approach

Abstract

Objective To research microsurgical removal of ambi - growing meningiomas in the falx cerebri and sagittal sinuses through interhemispheric approach. Method 21 cases were observed retrospectively. The treatment strategy was resection of the tumors by microsurgery and effective management of the sagittal sinus and falx intraopemtively. The effect was also analyzed. Results Total resection was achieved in 19 cases,including Simpson grade I in 2, Ⅱ in 13 and Ⅲ in 4,and subtotal resection in 2. Conclusions This approach has the advantage of shorter distance, more operating space and well protection for surrounding tissues. The surrounding structures affects the total resection rate.
