Abstract：
Direct access to the sphenoid lateral recess offers the best chance of sealing spontaneous cerebrospinal fluid (CSF) rhinorrhea caused by lateral sphenoid encephaloceles of the Sternberg canal defect.
We present a case of spontaneous left-sided sphenoid lateral recess CSF leak after previous unsuccessful transcranial surgery managed with an endoscopic endonasal transpterygoid approach (EETA). An anatomical-based step-by-step illustration of the EETA was presented in the surgical video.
This case demonstrates the value of endoscopic endonasal transpterygoid corridor in the exposure and manipulation of the sphenoid lateral recess.

摘要：
背景：直接进入蝶骨外侧隐窝提供了密封由Sternberg管缺损的蝶骨外侧脑瘤引起的自发性脑脊液（CSF）鼻漏的最佳机会。
方法：我们介绍了一例自发性左侧蝶骨外侧隐窝脑脊液漏的病例，此前经颅手术失败，经鼻内镜经膜入路（EETA）。在手术视频中介绍了基于解剖的EETA的逐步说明。
结论：该病例证明了内镜经鼻膜通道在蝶骨外侧隐窝的暴露和操作中的价值。
