The vidian nerve can be accessed in transcranial approaches in carefully selected patients to ensure its preservation and to serve as a landmark for sphenoid sinus entry. This report is to review a technique, evaluate it in laboratory settings, and present two illustrative cases. The study involves cadaveric dissection and illustrative cases. The study conducted in a cadaveric dissection laboratory. The object of the study is one cadaveric head and two illustrative clinical cases. Two cases using this approach were illustrated, and a cadaver dissection was performed in a step-by-step fashion. The vidian canal can be accessed by drilling the anterolateral triangle. Two illustrated cases were presented; in one, the vidian nerve was used as part of a corridor to access the sphenoid sinus for tumor delivery, and in the other, the technique was used to find and preserve the vidian nerve during transcranial resection. Careful identification of the vidian canal in transcranial surgery is a beneficial technique in carefully selected cases which allows identification of the nerve both for its preservation in selected cases and to create the vidian-maxillary corridor for tumor resection. Knowing the anatomy and pneumatization variants is important in the surgical approach.
在经过精心挑选的患者中，经颅入路可显露翼管神经，以确保其得以保留，并作为进入蝶窦的标志。本报告旨在回顾一种技术，在实验室环境中对其进行评估，并展示两个说明性病例。
该研究涉及尸体解剖和说明性病例。
该研究在尸体解剖实验室进行。
研究对象为一个尸体头部和两个说明性临床病例。
展示了两例采用该入路的病例，并对尸体进行了逐步解剖。
通过钻前外侧三角可显露翼管。展示了两个说明性病例；其中一例中，翼管神经被用作进入蝶窦以切除肿瘤的通道的一部分，另一例中，该技术用于在经颅切除术中寻找并保留翼管神经。
在经颅手术中仔细识别翼管是一种有益的技术，在精心挑选的病例中，它既能在特定病例中保留神经，又能为肿瘤切除创建翼管 - 上颌通道。了解解剖结构和气化变异在手术入路中很重要。
