Feasibility and accuracy of CARLO^© guided extradural anterior clinoidectomy

Abstract Anterior clinoidectomy is a surgical procedure used to access the central skull base, providing access to sellar and parasellar pathologies and vascular lesions in and around the cavernous sinus. However, the procedure is challenging and risky due to limited working space, restricted surgical view, and proximity to critical anatomical structures such as the carotid artery, oculomotor nerve, and optic nerve.
