Abstract
The ultimate purpose of meningioma surgery is to achieve total tumor removal and functional recovery without complications. Various steps are required for successful tumor removal including a thorough preoperative imaging study, preoperative embolization, intraoperative monitoring, suitable positioning and craniotomy, selection of surgical approach and surgical instruments. In order to improve the surgical outcome, we introduce our method to utilize the Sugita multipurpose head frame and rake retractor. Intraoperative head rotation of up to 35 degrees makes the surgical approach less irritable to the brain thanks to the use of gravitational force. Various methods manipulating the rake retractor enable rapid tumor eradication with minimal brain damage.
