CT引导下三叉神经节射频热凝术治疗三叉神经痛的疗效

目的评价CT引导下三叉神经节射频热凝术治疗三叉神经痛的疗效。方法三叉神经痛患者58例，均采用Hartel前入路法穿刺，在CT引导下进行三叉神经节射频温控热凝治疗。于手术后第2日评价疗效并观察并发症，后随访2年。结果术后2d优效56例（96．6％）、良效1例（1．7％）、差效1例（1.7％）、无效0例，优良率98．3％（57／58例）；术后随访2年优良率为96．6％（56／58例）。术后出现3例面部肿胀者，3d后肿胀消失；术后出现1例略感咀嚼无力者，1个月后恢复正常；1例术后出现角膜炎，6个月后治愈。未见严重并发症。随访2年，1年内无复发病例，2年内复发2例（3．4％）。结论CT引导下三叉神经节射频热凝术是一种有效的治疗三叉神经痛的方法。

Efficacy of CT-guided radiofrequency thermocoagulation on trigeminal ganglion in the treatment of tri- geminai neuralgia

Objective To evaluate the effects of radiofrequency thermocoagulation on trigemi nal ganglion under CT-guidance in the treatment for trigeminal neuralgia. Methods Fifty-eight patients with trigeminal neuralgia via Hartel approach method were treated with trigeminal ganglion radiofrequency thermocoagulation under CT guidance. Effects and complications were observed 2 days after the treatment, and followed-up for 2 years. Results The excellent, good, poor effects and ineffectiveness rates were 96.6% （56/58 cases）, 1.7% （1 case）, 1.7% （1 case） and 0%（0 case） respectively 2 days after the treatment, the excellent and good rate was 98.2%（57/58 cases）. The excellent and good rate was 96.6 % （56/58 cases） two years after the treatment. Facial swelling after the treatment relieved in three cases three days later; Chew weakness returned to normal in one case after 1 month; One case with keratitis was cured after six months. There were no serious com- plications in all patients. No recurrence was in one year and two cases recurred in two years. Conclu- sion CT guided trigeminal ganglion radiofrequency thermalcoagulation is an effective method for the treatment of trigeminal neuralgia
