Extended endoscopic endonasal transphenoidal approaches to the suprasellar region, planum sphenoidale & clivus

The standard unilateral endoscopic transsphenoidal approach has permitted a very wide vision around the sella, with the possibility of lreating lesions not confined to its strict limits. This possibility does not concern only anatomical studies [1, 2, 3, 4, 6] but dinical cases too, that have undergone surgery both within the suprasellar, and in the dival compartments, besides the parasellar area, that has already been treated above. Relevant series on these extended approach es by means of the endoscopic technique have not yet been presented in the main literature, but sporadic reports are now coming in and we will introduce the main guidelines of the procedure along with some illustrative cases.
