三叉神经痛的病理和治疗一直存在着争论。1967年Jannetta 根据Dandy1934年提出的后颅窝血管的变异可能是三叉神经痛性抽搐原因的观点,提出应用微血管减压治疗三叉神经痛。作者于1976～1981年间应用此法治疗了45例,其中37例一直保持着联系。现将此37例治疗情况报告如下。本组病例均为经内科治疗无效者。其中23例为首次应用血管减压术〈Ⅰ组〉;其余14例在进行微血管减压术前做过三叉神经破坏性手术〈Ⅱ组〉。绝大部分病人采取平卧 The pathology and treatment of trigeminal neuralgia has been controversial. In 1967, Jannetta proposed the use of microvascular decompression in the treatment of trigeminal neuralgia based on the changes in the likelihood of adverse cardiac arrest induced by Dandy in 1934. The authors treated 45 patients from 1976 to 1981 with 37 of them having been in contact. Now 37 cases of treatment are as follows. This group of patients were ineffective medical treatment. Among them, 23 cases were used for the first time in the group of vascular decompression. The other 14 cases were treated with the destructive trigeminal nerve operation before the microvascular decompression. Most patients take supine
