三叉神经痛射频热凝术中疼痛程度与病灶位置的关系

Relationship between lesion and intraprocedural pain during treatment of primary trigeminal neuralgia with radiofrequency thermocoagulation

目的：探讨三叉神经痛射频热凝术中三叉神经不同周围支在治疗过程中疼痛程度的关系。方法：对89例三叉神经痛患者行射频热凝治疗。上颌支18例，下颌支71例。治疗过程中采用视觉模拟评分法（VAS）对两组病例疼痛程度进行评估。结果：89例治疗效果均为优良，治疗过程中上颌支VAS评分中位数为7（5-9），下颌支VAS评分中位数为5（3-8）。两组VAS评分比较差异有统计学意义（P＜0．05）。结论：射频热凝术治疗三叉神经痛时，上颌支病灶会导致患者更为明显的疼痛。

Objective：To investigate the relationship between trigeminal branches and intraprocedural pain during treatment of primary trigeminal neuralgia with radiofrequency thermocoagulation. Method：Eighty-nine patients with PTN treated by radiofrequency. According to the local of lesion,patients were categorized into group 1 （maxillary nerve） and group 2（mandibular nerve. intraprocedural pain in treatment of radiofrequency thermocoagulation was valued by using visual analog scale（VAS）. The following data was recorded. Result：All patients were thrapyed ideadly. The VAS score of group 1 was 7 （5-9）,The VAS score of group 2 was 5 （3-8）.The relative VAS in group 1was much higher than that in group 2. There was significant difference between the two groups. Conclusion：Lesion of maxillary nerve would cause more severe pain in radiofrequency thermocoagulation.
