Surgical Anatomy & Approach Selection: Case Images & Positioning
Abstract: Tentorial meningiomas are intracranial tumors arising from the tentorium cerebelli, presenting significant surgical challenges due to their proximity to critical neurovascular structures, venous sinuses, cranial nerves, cerebellum, and brainstem. Their anatomical location and extension into the supratentorial or infratentorial compartments influence surgical planning and the selection of an appropriate operative approach. This case-based presentation examines the surgical anatomy, preoperative assessment, patient positioning, and microsurgical strategies involved in managing tentorial meningiomas. Particular emphasis is placed on magnetic resonance imaging and venous imaging to evaluate tumor attachment, compartmental extension, vascular relationships, and potential involvement of the transverse and sigmoid sinuses. Surgical approaches, including occipital, suboccipital, combined supratentorial-infratentorial, retrosigmoid, and presigmoid corridors, are considered according to tumor location and surrounding anatomical structures. Careful preoperative planning, preservation of venous drainage, appropriate patient positioning, and tailored surgical exposure are essential considerations for minimizing neurological complications. The discussion highlights the importance of individualized operative strategies, meticulous microsurgical dissection, and postoperative assessment in the management of these complex lesions. Comprehensive documentation of surgical findings, extent of resection, histopathological characteristics, and clinical outcomes remains necessary for evaluating treatment effectiveness and guiding subsequent management.
