在面神经支配的区域内发生不明原因的痉挛称为面部痉挛症。通常为单侧性,初发时阵发性发作,从眼轮开始,渐次向口角及面颊部扩大, 以后成为持续性,痉挛范围可波及面神经支配的全区,睡眠中也可发生,特别在面部随意运动或精神紧张时更易激发。发作时不能睁眼,日常活动均受影响。本症当前尚无特效疗法,病因不明,面神经阻滞、面神经切除、颞骨内减压等非选择性抑制神经兴奋的方法曾被推荐,但均不能避免再发。作者们在三年中用Mc Cabe,Fisch等推荐的选择性面神经部分切除术治疗15例面部痉挛患者,使痉挛变成麻痹,但麻痹较轻,效果良好,现将手术方法及疗效报告如下:
Unconscious spasms that occur within the area of the facial nerve are called facial spasms. Usually unilateral, paroxysmal episodes of first episode, starting from the eye wheel, gradually to the mouth and cheek enlargement, and later become persistent, the scope of spasms can affect the innervation of the facial nerve, sleep can occur, especially in Facial motility or mental stress more easily stimulated. Can not open eyes when the attack, daily activities are affected. The disease is currently no cure, the cause is unknown, facial nerve block, facial nerve resection, intramedullary decompression and other non-selective inhibition of nerve excitability has been recommended, but they can not avoid recurrence. In three years, the authors treated 15 patients with facial spasms with selective facial nerve resection recommended by Mc Cabe and Fisch et al. They made the spasms paralyzed but with less paralysis and good results. The surgical methods and efficacy are reported as follows:
