The authors report their experience in the treatment of essential facial neuralgia by differential thermocoagulation of the gasserian ganglion. This method is based upon the fact that small pain fibres (A delta and C) are more sensitive to warmth than large touch fibres. Thus progressive and controlled thermocoagulation of the trigeminal ganglion makes it possible to obtain selective destruction of the small fibres (analgesia without anaesthesia). 76 patients were treated using the method, and in 75 cases the symptoms of neuralgia disappeared immediately. Mortality is nil and morbidity insignificant other than the effects on the trigeminal nerve. The most serious complication (Approximately 10% of cases) was that of marked hypoaesthesia, rather than pure analgesia, in the coagulated area.
作者报告了他们采用半月神经节温差热凝术治疗原发性面部神经痛的经验。该方法基于这样一个事实，即细小的痛觉纤维（Aδ和C）比粗大的触觉纤维对热更敏感。因此，对三叉神经节进行逐步且可控的热凝术能够选择性地破坏细小纤维（产生无痛觉但无麻醉效果）。76例患者采用该方法进行治疗，其中75例神经痛症状立即消失。除对三叉神经产生影响外，死亡率为零，发病率也微乎其微。最严重的并发症（约10%的病例）是在凝固区域出现明显的感觉减退，而非单纯的痛觉缺失。
