摘　　要：目的：探讨CT引导下经皮穿刺卵圆孔阻滞治疗三叉神经痛的技术。方法：实验组：头颅颅骨标本一具，经卵圆孔行不同方位冠状及横断扫描，观察最佳卵圆孔进针路径。对照组：10例正常志愿者仰卧扫描床，采用不同角度，观察舒适及耐受程度；64例三叉神经痛患者，按照半冠状面摆位、扫描卵圆孔、引导进针，行阻滞治疗。结果：实验组穿刺卵圆孔的最佳体位及层面，以机架倾斜15°～20°，头架倾斜10°～15°，体标穿刺点位于颧骨下1cm的区域，穿刺路径最短、最安全。对照组于实验位置仰卧2h无不适；64例患者，63例CT引导穿刺、确定针尖在卵圆孔时，行阻滞治疗，成功率98.3％，无明显不良反应。结论：CT引导下经皮穿刺卵圆孔阻滞治疗三叉神经痛具有简便易行、定位准确，并发症少、痛苦小的优点。Objective：To introduce a technique of CT-guided percutaneous foramen ovale blocking to treat trigeminal neruralgia. Methods： Experiment group：a skull sample was used. The skull was scanned through the foramen ovale as the center to find an optimal section for puncturing. Control group;ten normal persons （5 male,5 female） were supine in different positions. Patients group,Of 64 patients （male 26 ,female 39; ranging 43 to 77 years with a mean of 59） with trigeminal neruralgia who were treated for blocking therapy by CT-guided puncture. Results：The best position was CT gantry tilted 10 15 degree and patients were supine with head extended 10- 15 degree. 98.3 % patients were successfully treated,no serious complications occurred. Conclusion：CT-guided percutaneous foramen ovale blocking therapy is precise and highly effective with minimal trauma and no pain. It＇s a technique of option for treating trigeminal neruralgia.
