A 56-year-old woman previously treated by a retrogasserian neurectomy for a right tic douloureux was rendered free of pain, but complete anaesthesia of the right half of her face remained. Seven years later, she developed a typical left trigeminal neuralgia. Contralateral rhizotomy was refused because of the patient's concern about having bilateral facial anaesthesia. Through a suboccipital craniectomy, the trigeminal nerve was decompressed from a thickened arachnoid membrane and a large bridging vein near the root entry zone. After eighteen months, the patient was free of pain with intact facial sensations on the left side. Therapeutic considerations in cases of bilateral trigeminal neuralgia are discussed.
一名56岁女性曾因右侧三叉神经痛接受半月神经节切除术，术后疼痛消失，但右侧面部仍完全麻木。7年后，她患上了典型的左侧三叉神经痛。由于患者担心出现双侧面部麻木，拒绝了对侧神经根切断术。通过枕下颅骨切除术，在神经根入区附近从增厚的蛛网膜和一条粗大的桥静脉中对三叉神经进行减压。18个月后，患者疼痛消失，左侧面部感觉完好。本文讨论了双侧三叉神经痛病例的治疗考虑因素。
