痉挛可局限于眼轮匝肌局部或进而波及面神经支配的其它区域,如下面部和颈部肌肉。当下面部间歇性运动伴随眼睑痉挛,这种疾病称为自发性口面肌张力障碍或Meige综合征。倘波及下颌更大范围,则称为口下颌肌张力障碍或Breughel综合征。倘不随意肌收缩扩展到其它颅神经支配的肌肉(最常见的是第Ⅴ、Ⅸ、Ⅹ、Ⅺ和Ⅻ颅神经),则称为节段性颅神经肌张力障碍。看来好像这些肌张力障碍是表 Spasms can be confined to the orbicularis oris and other areas of the facial nerve, such as lower facial and neck muscles. When the lower part of the intermittent movement accompanied by blepharospasm, this disease is called spontaneous oral dystonia or Meige syndrome. If the spread to the wider jaw, then called oral mandibular dystonia or Breughel syndrome. If not involuntary muscle contraction extended to other cranial nerves of the muscles (the most common is the â ... ¢, â ... ¡, â ... ¡, â ... ¢ and â ... ¡cranial nerve), then called segmental cranial dystonia. It seems like these dystonias are tables
