摘要
目的采用鼻内镜经鼻径路对咽旁间隙区域的重要血管、神经结构进行解剖,掌握其分布的规律,以寻找用于指导手术有效的解剖标志并测量相关的数据,从而为处理该部位病变的鼻内镜手术提供解剖依据。方法对福尔马林浸泡的尸头4例(8侧),模拟鼻内镜下鼻径路咽旁间隙进行解剖。对手术入路的安全范围进行评估,并观测手术径路的重要标志和毗邻关系,测量相应的解剖数据。结果经鼻径路咽旁间隙前为咽鼓管,外为翼内板残端,上为蝶窦底、破裂孔,下为后鼻孔下缘,内为头长肌。翼管的长度、咽鼓管峡部与颈内动脉的距离分别为(14.50±1.77)mm、(11.04±1.08)mm。结论鼻内镜下经鼻径路可以暴露咽旁间隙的茎突前间隙部分,在该区域保护颈内动脉是关键。该径路以颈内动脉(interal carotid artery,ICA)的外口和破裂孔两点连线水平作为上界,相对安全地暴露ICA的颈段。
Objective To provide anatomical data for the operation of parapharyngeal space via endonasal endoscopic approach. Methods Anatomic study was performed in 4 formalin-soaked adult cadaver heads （ 8 sides ） by mimicking endoscopic surgery of parapharyngeal space via endonasal approach. In the study, the safety margin of the surgical field was evaluated, the important anatomic landmarks and their relationships were observed, and the relevant anatomic data were measured. Results The length of pterygoid canal was 14. 50 ±1. 77 ram, and the distance between isthmus of Eustachian tube and internal carotid artery was 11.04 ±1.08 mm. Conclusions The pre-styloid space can be exposed via endoscopic endonasal approach with proper protection of internal carotid artery （ ICA ） . For the protection of ICA, it is essential to expose ICA below the imaginary line from external aperture of carotid canal to foramen lacerum.
