Figure 1: Demonstration of the extended endoscopic endonasal (transsphenoidal endosellar-transtubercular-transplanum) approach on a midsagittal magnetic resonance image. Area in yellow color indicates exposure obtained in a standard endoscopic endonasal (endosellar) approach. Additional exposure in extended endoscopic endonasal approach is achieved by removing the tuberculum sellae and planum sphenoidale, as shown in orange color
