Endoscopic endonasal posterior clinoidectomy represents an important maneuver to improve access and visualization of the retrosellar and upper clivus area [1]. Three different techniques have been described in order to access and remove the posterior clinoid: 1) the intradural pituitary transposition [2], the interdural pituitary transposition [3] and a completely extradural technique [4].
We present here a case of retrosellar and retroclival chordoma that has been removed through endoscopic endonasal approach. Technical nuances of the endonasal extradural posterior clinoidectomy are presented.
Endoscopic endonasal extradural posterior clinoidectomy allows to access this complex anatomical region with the advantage of avoiding major bleeding from the cavernous sinus and endocrinological impairment.
经鼻内镜颅底后床突切除术是改善鞍后和颅颈交界区显露的重要手段[1]。为了进入和切除颅底后床突，已经描述了三种不同的技术：1）经硬膜内垂体移位[2]、经硬膜外垂体移位[3]和完全经硬膜外技术[4]。
我们在此介绍一例通过经鼻内镜入路切除鞍后和斜坡脊索瘤的病例。本文介绍了经鼻内镜硬膜外颅底后床突切除术的技术要点。
经鼻内镜硬膜外颅底后床突切除术可以进入这个复杂的解剖区域，避免了海绵窦大出血和内分泌功能障碍的风险。
