Abstract

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.
