摘要：

目的：利用三维重建技术测量圆孔到颈内动脉虹吸段的安全距离，为翼腭窝入路的手术提供指导。方法：对121名志愿者的头颅进行计算机薄层CT扫描。标注颈内动脉虹吸段（A点）和圆孔（B点）位置，利用三维重建技术建立一个平行于眼耳平面的和鼻中隔所在平面的坐标系，其坐标原点为A点。C点是A点在一个平行于眼耳平面的平面上的投影点，且B点经过该平面。D点是C点在一个平行于鼻中隔平面的平面上的投影点，且B点经过该平面。测量AC与BC的距离，计算A点与B点之间的距离，测量AB所在直线与冠状面、矢状面和水平面3个平面之间的角度。结果：AC间的长度为（13.22±3.79）mm（范围为8.33~105.67 mm；95% CI：8.55~21.39 mm）。与矢状面的角度为33.54°±9.23°（范围为5.38°~66.58°；95% CI：30.88°~34.20°）。与冠状面的角度为53.17°±10.48°（范围为5.60°~75.02°；95% CI：51.29°~55.06°）。与水平面的角度为9.43°±12.91°（范围为-28.44°~82.22°；95% CI：7.11°~11.76°）。结论：通过薄层CT扫描技术得到经翼腭窝入路手术中圆孔到颈内动脉虹吸段的安全距离。

Abstract:

Objective: To measure the safe range from the foramen rotundum to the siphon of internal carotid artery using three-dimensional reconstruction technique, and to provide guidance for operation through pterygopalatine fossa.Methods: The skulls of 121 volunteers were scanned to get the final results with thin-section computed tomographic images. The position of the siphon of internal carotid artery (point A) and foramen rotundum (pointB) were ascertained. Three-dimensional reconstruction technique was used to build a coordinate system paralleled to the frankfort horizontal plane and the nasal septum plane. The coordinate system took point A as the coordinate origin.Point C and point D were the projections of point A in two planes parallel with frankfort horizontal plane and nasal septum plane which included point B.The distances of AC,AB, and BC were measured.The angles of the line went through A and B to the three planes were also measured. Results: The distance of AC was measured as 13.22 (3.79) mm (range,8.33-105.67 mm;95%CI:8.55-21.39 mm).The angle to the sagittal plane was measured as 33.54 (9.23)°(range,5.38-66.58°;95%CI:30.88-34.20°). The angle to the coronal plane was measured as 53.17 (10.48)° (range,5.60-75.02°;95%CI:51.29-55.06°).The angle to the horizontal plane was measured as 9.43(12.91)mm (range,-28.44-82.22; 95%CI:7.11-11.76).Conclusion: The safety distance from foramen rotundum to the siphon of internal carotid artery in the operation through pterygopalatine fossa (PPF) under nasoendoscope is obtained by thin-section computed tomographic images.
