Schematic diagram of surgical approaches for resection of posterior clinoid meningiomas. Current approaches for resection of posterior clinoid meningiomas include anterolateral approaches (the classical pterional approach and the Dolenc approach), the lateral approach (the subtemporal approach), posterolateral approaches (the presigmoid transpetrosal approach, the retrosigmoid approach, and the EF-SCITA approach), and the complex route (the FTOZ approach). FTOZ: frontotemporo-orbito-zygomatic orbitozygomatic approach; EF-SCITA: endoscopic far-lateral supracerebellar infratentorial approach.
