Jaw tremor in the context of dystonia is not well recognized.
We describe 7 women (average onset age 70) with jaw tremor and dystonia.
All had features of primary dystonia. Applying MDS criteria for tremor, 3 had "dystonic jaw tremor"; 4 had "jaw tremor associated with dystonia". Drugs were unhelpful. Botulinum toxin injections proved effective in 1 case.
We propose the entity of "jaw tremor and dystonia". It is distinct from jaw tremor due to other causes including Parkinson's disease and essential tremor.
肌张力障碍背景下的下颌震颤尚未得到充分认识。
我们描述了7名患有下颌震颤和肌张力障碍的女性（平均发病年龄70岁）。
所有患者均有原发性肌张力障碍的特征。根据运动障碍协会（MDS）的震颤标准，3例为“肌张力障碍性下颌震颤”；4例为“与肌张力障碍相关的下颌震颤”。药物治疗无效。肉毒杆菌毒素注射在1例患者中证明有效。
我们提出“下颌震颤和肌张力障碍”这一实体。它与包括帕金森病和特发性震颤在内的其他原因引起的下颌震颤不同。
