鼻内镜翼腭窝上颌神经切除治疗三叉神经痛

目的：探讨一种有效治疗原发性三叉神经第二支（上颌支）痛的手术方法。方法：对136例（136侧）原发性三叉神经第二支（上颌支）痛的患者在鼻内镜下经上颌窦后进路翼腭窝内圆孔处切断翼腭窝神经和眶下神经全长切除。结果：135例患者术后疼痛消失。经2~8年随访观察,118例患者无复发疼痛,但有轻度术侧上颌神经支配区麻木和感觉异常。结论：鼻内镜下经上颌窦后进路翼腭窝内圆孔处切断翼腭窝神经和眶下神经全长切除适用于原发性三叉神经第二支（上颌支）痛的患者,手术效果好,避免了开颅手术的危险,在临床上值得推广应用。

The treatment of trigeminal neuralgia by resecting maxillary nerve and infraorbital nerve under the endoscopy at the pterygopalatofossa through approach to the maxillary sinus

Objective：This paper presents a method for treating maxillary neuralgia, the second division of tri- geminal nerve. Method：One hundred and thirty six cases with 136 trigeminal neuralgia were treated from 2004 to 2011. All patients were treated with endoscopic surgery at the pterygopalatofossa through approach to the maxil- lary sinus for resecting maxillary nerve and infraorbital nerve. Result： One hundred and eighteen patients were re- lieved after operation and no recurrence of neuralgia was occured after 2 to 8 years of follow-up. Conclusion：This method had the advantages of avoiding to operate eraniotomy with no complications, which was performed easily with valid efficacy.
