Trigeminal neuralgia is a unique neuropathic syndrome confined to the trigeminal system with no analog in the somatic dermatomes or the other cranial nerves. Medical treatment remains the first line of treatment with carbamezapine as the drug of choice. Surgery, central or peripheral is indicated when medical treatment fails or its side effects diminishes quality of life. No surgery offers a permanent cure. Recurrence rates are highest in the most peripheral techniques but these also have the lowest morbidity. Cryotherapy produces a reliable, prolonged and reversible nerve block with no aggravation of symptoms. It is a simple and repeatable procedure in patients who want to avoid major surgery or where it is contra-indicated.
三叉神经痛是一种独特的神经病理性综合征，局限于三叉神经系统，在躯体皮节或其他颅神经中无类似情况。药物治疗仍然是首选的治疗方法，卡马西平是首选药物。当药物治疗失败或其副作用降低生活质量时，可考虑进行中枢或外周手术。没有一种手术能提供永久性治愈。复发率在最外周的技术中最高，但这些技术的发病率也最低。冷冻疗法可产生可靠、持久且可逆的神经阻滞，且不会加重症状。对于想要避免大手术或存在手术禁忌的患者，这是一种简单且可重复的手术。
