目的为眶入路法行翼腭窝穿刺提供新的进针路径。方法对77个(154侧)成人颅的眶和翼腭窝进行相关的观察和测量。结果眶外缘点至眶外下缘点、圆孔外口下缘、眶上裂后端、眶下裂前端的距离分别为:左(4.93±1.80)mm,右(4.02±2.05)mm;左(43.74±2.75)mm,右(43.80±2.89)mm;左(47.83±2.47)mm,右(47.74±2.53)mm;左(17.74±2.18)mm,右(17.43±1.97)mm。穿刺针(直针)由眶外缘点进入翼腭窝的成功率为:左侧96.10%;右侧93.51%。对穿刺针(直针)进入翼腭窝失败者改用弯针穿刺,直针和弯针由眶外缘点进入翼腭窝的总成功率为:左、右均达98.70%。结论经眶外缘点行眶入路翼腭窝穿刺可明显提高穿刺成功率。
The purpose of the orbital approach to the pterygopalatine fossa puncture provides a new path of the needle. Methods The cranial orbital and pterygopalatine fossa of 77 (154 sides) adults were observed and measured. Results The distance from the rim of the orbital rim to the point of the inferior orbital rim was 4.19 ± 1.80 mm in the left and 4.02 ± 2.05 mm in the right, respectively. Left (43.74 ± 2.75) mm, Right (43.80 ± 2.89) mm, Left (47.83 ± 2.47) mm, Right (47.74 ± 2.53) mm, Left (17.74 ± 2.18) mm, Right (17.43 ± 1.97) mm. The success rate of puncture needle (straight needle) entering the pterygopalatine fossa from the rim of the orbital rim was 96.10% on the left and 93.51% on the right. The total success rate of inserting the needle into the pterygopalatine fossa into the pterygopalatine fossa with the needle inserted into the pterygopalatine fossa was 98.70%. Conclusion Perforation of the pterygopalatine fossa through the orbital rim can significantly improve the success rate of puncture.
