目的 :探讨一种有效治疗年老体弱患者单独原发性三叉神经上颌支痛的手术方法。方法 :对 39例 4 0侧原发性三叉神经上颌支痛的年老体弱患者在内镜下经上颌窦至翼腭窝在圆孔处切除上颌神经 0 .5～ 1.0cm。结果 :术后全部病例疼痛消失 ,经 2年以上观察 ,术侧上颌神经分布区麻木、感觉异常 ,但无疼痛 ,2例分别于术后 5个月和 12个月出现术侧下颌神经痛 ,上颌区无痛。结论 :内镜下经上颌窦至翼腭窝行三叉神经上颌支部分切除术适用于年老体弱、长期单独局限于上颌神经痛的患者 ,但要求其上颌窦腔有一定程度发育和无炎症 ,手术远期效果好 ,避免了开颅手术的危险 ,在内镜下完成该手术较显微镜下更方便
Objective: To explore an effective surgical treatment of elderly and frail patients with primary trigeminal nerve pain alone surgery method. Methods: Thirty-nine patients with frail elderly patients with 40 cases of primary trigeminal nerve maxillary pain were dissected from the maxillary sinus to the pterygopalatine fossa for 0.5-5 cm. Results: The pain disappeared in all the cases after operation. After 2 years of observation, the maxillary nerve distribution on the operation side was numb, sensory abnormality, but no pain. Two cases had postoperative operative complications of mandibular neuralgia at 5 and 12 months after operation, Maxillary area painless. Conclusion: The maxillary sinus to the pterygopalatine fossa under endoscopy is suitable for the elderly patients who are frail, long-term and limited to maxillary neuralgia. However, the maxillary sinus cavity is required to develop to a certain extent and have no inflammation , Long-term effect of surgery, to avoid the risk of craniotomy, endoscopic surgery to complete the surgery more convenient than a microscope
