The document discusses endoscopic transglabellar and supraorbital approaches for skull base surgery. It provides information on using these approaches to remove large macroadenomas and craniopharyngiomas. Giant craniopharyngiomas may require a combination of endoscopic transnasal and frontal or supraorbital approaches. The endoscopic supraorbital approach involves making a small incision in the eyebrow and keyhole opening to access the anterior cranial fossa.
