Facial tremor occurring on smiling is a rare phenomenon and has been described (to the best of our knowledge) in the literature only once. We describe two patients who presented with a bilateral facial tremor that occurred only on smiling and other activation of therisorii muscles and had a high frequency of 9 Hz. One patient additionally suffered from young-onset Parkinson's disease, whereas the other had no further neurological symptoms or signs apart from this tremor. Anti-parkinsonian medication was unhelpful for the facial tremor in the patient with Parkinson's disease. Tremor on smiling may be a discrete entity or may be associated in some cases of Parkinson's disease.
微笑时出现的面部震颤是一种罕见现象，据我们所知，在文献中仅被描述过一次。我们报告了两名患者，他们表现为仅在微笑及其他笑肌激活时出现双侧面部震颤，频率为9Hz。其中一名患者还患有早发性帕金森病，而另一名患者除了这种震颤外没有其他神经症状或体征。抗帕金森病药物对患有帕金森病的患者的面部震颤无效。微笑时的震颤可能是一种独立的病症，也可能在某些帕金森病病例中出现。
