什么原因导致面部疼痛？
三叉神经痛是导致面部疼痛的原因之一。疼痛来自三叉神经、引发为尖锐的、刀割般的疼痛，持续几秒钟到几分钟。说话、刷牙、吃饭或化妆都会触发疼痛。
三叉神经痛的治疗方法是什么？
必须进行核磁共振以排除大脑内三叉神经受压迫的可能。血管或者肿瘤都可能压迫神经、引起三叉神经痛。如果发生这种情况，就需要转介神经外科医生。对于原发性三叉神经痛（没有疼痛原因）、抗癫痫和抗忧郁药物如卡马西平、加巴喷丁或普瑞巴林可能有帮助。严重三叉神经痛就必须使用射频消融治疗。
什么是射频消融？
一根特殊的射频针插入三叉神经节中、通过一台射频机器产生热能。这种热能通过针尖传输，摧毁三叉神经的疼痛分支。这是一种日间手术，在轻度镇静下、凭着扫描引导进行。射频消融治疗有效减轻95%的面部疼痛。
