The purpose of this study was to describe the technique used to safely identify the petrous carotid artery during expanded endonasal approaches to the skull base. A series of 20 cadaveric studies was undertaken to isolate the vidian artery and nerve and to use them as landmarks to the petrous internal carotid artery (ICA). Twenty-five consecutive paraclival endoscopic cases were also reviewed to determine the consistency of the vidian artery in vivo as an intraoperative landmark to the ICA. These data were then correlated with results from a separate study in which computed tomography scans from 44 patients were evaluated to delineate the course of the vidian canal and its relationship to the petrous ICA. In all 20 cadaveric dissections and all 25 surgical cases, the vidian artery was consistently identified and could be reliably used as a landmark to the ICA. The correlation between anatomical and clinical data in this paper supports the consistent use of the vidian artery as an important landmark to the petrous ICA.
本研究的目的是描述在扩大经鼻入路至颅底手术中安全识别岩骨段颈内动脉所使用的技术。进行了一系列20例尸体研究，以分离翼管动脉和神经，并将它们用作岩骨段颈内动脉（ICA）的标志。还回顾了连续25例斜坡旁内镜手术病例，以确定翼管动脉在体内作为ICA术中标志的一致性。然后将这些数据与另一项研究的结果进行关联，在该研究中评估了44例患者的计算机断层扫描，以描绘翼管的走行及其与岩骨段ICA的关系。在所有20例尸体解剖和所有25例手术病例中，均能持续识别出翼管动脉，并可将其可靠地用作ICA的标志。本文中的解剖学和临床数据之间的相关性支持将翼管动脉持续用作岩骨段ICA的重要标志。
