三叉神经痛一般可分为原发性和继发性两类。原发性三叉神经痛,由于目前发病原因未明,故无特效治疗方法。对局限在一支的三叉神经痛,一般可采用周围神经撕脱术,但有时无效,且易复发。笔者曾对两例原发性上颌支三叉神经痛,经眶底将神经扯除,效果良好,至今未复发。 Trigeminal neuralgia can be divided into two types of primary and secondary. Primary trigeminal neuralgia, the current etiology is unknown, so no special treatment. Of the limitations of a trigeminal neuralgia, the general use of peripheral nerve avulsion surgery, but sometimes ineffective, and easy to relapse. I had two cases of primary maxillary branch trigeminal neuralgia, the nerve removed through the orbital, the effect is good, has not relapsed.
