摘要
目的:探讨三维CT重建定位下经周围支射频温控热凝术治疗三叉神经痛的疗效。方法:将160例原发性三叉神经痛患者随机分为2组,每组80例.分别在三维CT重建及非重建条件下.经三叉神经周围支及半月节行射频热凝治疗,统计分析其术后即刻疗效及复发率。结果:术后即刻疗效比较,重建引导组有效率93.75%,非重建引导组有效率92.50%,无显著性差异(P>0.05)。经1～4.5年的随访,重建引导组总复发率31.25%,非重建引导组复发率47.50%,重建引导组复发率显著低于非重建引导组(P<0.05):涉及三叉神经第一支射频治疗22例.复发3例。结论:三维CT重建定位指导下,经三叉神经周围支行射频温控热凝术操作方便、安全、适应证广,止痛效果确切,远期疗效优于直接穿刺射频。
Objective： To investigate the therapeutic effect of trigeminal peripheral branches in radiofrequency thermocoagulation under the guide of 3D computerized tomography for the treatment of idiopathic trigeminal neuralgia. Methods： 160 patients with idiopathic trigeminal neuralgia were divided into 2 groups randomly and equally. All patients in group 1 were underwent radiofrequency thermocoagulation of trigeminal peripheral branches or semilunar ganglion and guided by 3D computerized tomography .Patients in group 2 were underwent trigeminal peripheral branches or semilunar ganglion radiofrequency thermocoagulation. The immediately therapeutic effect and the recurrence rate of 2 groups were statistically ananlyzed. Results： The immediately effective rate of guided group was 93.75%, while it was 92.50% in group 2. There was no significant differences between them （P〉0.05）. After 4.5 years follow up, the recurrence rate of guided group was 31.2% and it was 47.50% in without guide group, and the former is smaller than the later significantly （P〈0.05）. Conclusion： Trigeminal peripheral branches radiofrequency thermocoagulation under the guide of 3D computerized tomography for the treatment of idiopathic trigeminal neuralgia is convenient and safe, therapeutic effect is certain .
