概述

偏侧面肌痉挛是一种神经系统疾病,指一侧面部的肌肉不自主地抽搐。偏侧面肌痉挛最常由血管触及面神经引起,但可能由面神经损伤或肿瘤引起,也可能没有原因。

症状

Common symptoms of hemifacial spasm include twitching or contracting of muscles in the face that are usually:

  • On one side of the face
  • Uncontrollable
  • Painless

These contractions often start in the eyelid, then may progress and affect the cheek and mouth on the same side of the face. At first, hemifacial spasms come and go. But eventually, usually over the course of several months to a few years, they occur almost constantly.

Occasionally, hemifacial spasms may occur on both sides of the face. However, the twitching doesn't occur on both sides of the face at the same time.

病因

偏侧面肌痉挛大多由血管接触面神经引起。它也可能由面神经损伤或肿瘤引起。有时并无明确的病因。
