目的探讨CT定位下半月神经节射频热凝治疗第Ⅰ+Ⅱ支受累的三叉神经痛的方法及其效果。方法先以定位架帮助,后在CT定位下采用卵圆孔前入路穿刺,局麻下行半月神经节射频热凝术。第Ⅰ支热凝温度和时间为65℃、67℃,各维持60 s;第Ⅱ支为70℃、75℃,各2～3 min。结果三叉神经第Ⅰ+Ⅱ支痛患者13例,全部病例术后当日三叉神经痛发作完全消失。随访3～16个月,无疼痛复发。结论定位架帮助,在CT定位下,经卵圆孔前入路穿刺,采用半月神经节射频热凝术治疗第Ⅰ+Ⅱ支受累的三叉神经痛是一种安全、疗效好的方法。
Objective To investigate the method and effect of radiofrequency thermocoagulation in the second half of the ganglion neurotomy for the treatment of trigeminal neuralgia with stage Ⅰ + Ⅱ branches under CT localization. Method to help positioning the first frame, after the use of CT foramen ovale approach approach, local anesthesia with semilunar ganglion radiofrequency coagulation. The first branch of the thermal coagulation temperature and time of 65 ° C, 67 ° C, each maintained 60 s; the second branch of 70 ° C, 75 ° C, 2 ~ 3 min. Results Trigeminal nerve Ⅰ + Ⅱ patients with thrombolysis in 13 cases, all cases of the day after the operation completely disappeared trigeminal neuralgia. Follow-up 3 to 16 months, no pain recurrence. CONCLUSION: The positioning frame helps to treat the trigeminal neuralgia with involvement of the first and the second branches by radiofrequency thermal coagulation of the semilunar ganglion under the CT localization with anterior foramen ovale approach. This is a safe and effective method.
