Blepharospasm is a cranial nerve dysfunction in which involuntary and uncontrollable forcible lid closure occurs. Surgical treatment is far from ideal, but the condition can be improved by sectioning the branches of the facial nerve plexus which supply the orbicularis oculi, the frontalis and corrugator muscles, and the midfacial muscles. Not all patients with blepharospasm should be operated upon, since they may expect too much or may enjoy the attention their invalidism has given them. Ectropion of one or both lower lids may occur, and the most severe of all complications is recurrence. This may happen despite a careful microscopic search for the nerve fibers and their division and avulsion. Blepharospasm patients often require considerable psychological support.
眼睑痉挛是一种颅神经功能障碍，表现为眼睑不自主且无法控制地强力闭合。手术治疗远非理想，但通过切断支配眼轮匝肌、额肌、皱眉肌及面中部肌肉的面神经丛分支，病情可得到改善。并非所有眼睑痉挛患者都适合手术，因为他们可能期望过高，或者享受因疾病而获得的关注。可能会出现一侧或双侧下睑外翻，最严重的并发症是复发。即便在显微镜下仔细搜寻神经纤维并进行切断和撕脱，仍可能发生复发。眼睑痉挛患者通常需要相当多的心理支持。
