The authors reviewed a series of 38 consecutive patients with trigeminal neuralgia treated by percutaneous thermocoagulation in 1984-90. In 10 patients in whom the result of the treatment was unsatisfactory the coagulation was repeated (in 2 out of 10 twice). The analysis of the results showed that good outcome was connected with permanent anaesthesia in the area innervated by the coagulated branch. If anaesthesia was not present 24 hours after the treatment, it suggested that an insufficient lesion was done and consequently unsatisfactory result was likely. In patients in whom there was a sensory impairment after either thermocoagulation or other form of treatment (injection of alcohol or rhizotomy) repeated thermocoagulation not only did not give good results but could lead to worsening of the pain.
作者回顾了1984年至1990年间接受经皮热凝治疗的38例连续性三叉神经痛患者。10例治疗效果不满意的患者接受了重复热凝治疗（10例中有2例重复了两次）。结果分析表明，良好的治疗效果与热凝分支所支配区域的永久性麻醉有关。如果治疗后24小时仍无麻醉效果，则提示热凝损伤不足，治疗效果可能不理想。在接受热凝或其他治疗方式（酒精注射或神经根切断术）后出现感觉障碍的患者中，重复热凝不仅效果不佳，还可能导致疼痛加重。
