翼管走行的解剖测量及其临床意义

目的为临床经鼻内镜翼管神经穿刺手术提供解剖学依据。方法利用金属探针及X线片的辅助,主要对56侧颅骨翼管的相关骨性结构、解剖标志,特别是走行方向定位进行观测。结果翼管长度为（16.03±1.48）mm,双侧前口间距为（27.56±3.11）mm,双侧后口间距为（34.41±3.37）mm;鼻骨下缘中点与翼管前口距离（60.70±8.86）mm,前鼻棘至翼管前口距离为（58.16±5.80）mm,两者连线与翼管之间前夹角为（33.50±3.52）°;翼管与颅骨中矢状面之间的夹角（取双侧夹角的平均值）为（11.95±1.12）°,翼管与法兰克福平面间夹角为（6.86±3.37）°;翼管与下鼻道平面间夹角为（9.68±4.60）°。结论本研究的测量数据可作为经鼻内窥镜翼管神经穿刺术的重要解剖学参数。

Measurement of the pterygoid canal and its clinical significance

Objective To provide an anatomical basis for vidian neurotomy by endonasal endoscopy.Methods With the assistant of a metal stylet and X-ray,the pterygoid canal and its track and orientation were dissected and observed on 56 sides of a skull.Results The average length of the pterygoid canal was 16.03±1.48 mm and from the lower border midpoint of the nose bone to the anterior openings of the pterygoid canal was 60.70 ±8.86mm.Spacing between the twin anterior openings of the pterygoid canal was 27.56±3.11 mm and between the twin back opening of the pterygoid canal was 34.41±3.37 mm.The angle of the double pterygoid canal was 23.9±2.25°.The average length from the front nose thorn to the anterior opening of the pterygoid canal was 58.16±5.80 mm and the average angle between their line and the pterygoid canal was 33.50±3.52°.The average angle between the pterygoid canal and the Frankfurt horizontal plane was 6.86±3.37° and between the pterygoid canal and the nose fundus plane was 9.68±4.60°.Conclusion The resultant data attained in this research can be used as momentous parameters for vidian neurotomy by nostril endoscopy.
