脉冲射频术和射频热凝术治疗眶下神经痛的疗效评价

目的 研究脉冲射频术(PRF)和射频热凝术(RFTC)对原发性眶下神经痛的治疗效果.方法 将16例原发性眶下神经痛患者随机分为PRF组和RFFC组,分别行PRF和RFTC.记录患者的一般资料,于术前、术后1 h和1、7、15 d及1、3、6个月行数字疼痛评分(NRS),评估疼痛缓解程度(PR)和治疗有效率.结果 RFTC组第1、2、3次手术前、后阻抗分别为(490 ±86)Ω和(424±82)Ω、(492±90)Ω和(432±84)Ω、(481±98)Ω和(409±85)Ω,术后明显降低(P均＜0.05);PRF组和RFTC组术前NRS评分分别为9(7～10)分和8.5(7～10)分,术后各时间点均明显低于术前(P均＜0.05);PRF组在第7、15天的PR为3分(0～4分),RFTC组为4分(3～4分),PRF组低于RFTC组(P＜0.05);但2组各时间点治疗有效率比较差异无统计学意义(P均＞0.05).PRF组术后出现麻木,但1周内消失;而RFTC组患者麻木严重.结论 PRF对原发性眶下神经痛的近期疗效与射频热凝术一致,但神经损伤症状轻,是一种安全、有效的治疗方法.

Pulsed radiofrequency and radiofrequency thermocoagulation in the treatment of idiopathic infraorbital nenralgia

Objective To study the effects of pulsed radiofrequency(PRF)and radiofrequency thermocoagulation(RFTC)in the treatment of idiopathic infraorbital neuralgia.Methods 16 patients suffering idiopathic infraorbital neuralgia were randomly divided into PRF(n=8)and RFTC(n=8).Numeral rating scale(NRS),pain relief(PR)and effective rate of treatment was performed before operation and at 1 hour、1 st day、7th day、15th day、1 st month、3rd month and 6th month after operation.Results The preoperative and postoperative impedance of thefirst,second and third operation in RFTC group were(490±86)Ω and(424±82)Ω,(492±90)Ω and(432±84)Ω,(481±98)Ω and(409±85)Ω respectively and the postoperative impedance was significantly decreased(P＜0.05).The preoperative NRS in group PRF and RFTC were 9(7～10)and 8.5(7～10)respectively and the postoperative NRS at all points in two groups were significantly decreased as compared with the preoperative NRS(P＜0.05).The PR at 7 and 15d in group PRF were 3(0～4)and that in group RFFC were 4(3～4)(P＜0.05).There were no significant differences in effective rate of treatment at each time between two groups(P＞0.05).Numbness appeared after operation in group PRF and disappeared in a week,however,that was persistent and all sense disappeared in group RFTC.Conclusion Curative effect of PRF for idiopathic infraorbital neuralgia is as well as RFTC and it is a kind of safe and effective technology that causes less side effects.
