This video demonstrates endoscopic endonasal resection of a giant pituitary macroadenoma with bilateral cavernous sinus extension. Following debulking of the sellar component, angled endoscopes facilitated dissection around carotids and suprasellar extension, enabling optic chiasm decompression. A low-flow CSF leak was repaired with synthetic dural graft and nasoseptal flap. Anatomy of the cavernous sinus and abducens nerve is reviewed through cadaveric dissection. The case emphasizes technical strategies for safe tumor removal in Knosp grade 4 lesions.
