A Case Report of Cervical Dystonia Complicated by Oromandibular Dystonia

Here, we report a case of stiff neck as a symptom of cervical dystonia and oromandibular dystonia as a symptom of trismus. The patient was a 37-year-old male who was examined at a nearby dental clinical after noticing some stiffness of the neck and trismus at the same time. However, the cause was unknown and the symptoms were neglected. Thereafter, the symptoms worsened and mouth opening became strongly restricted, making dental treatment impossible. He was thus referred to our institution where he was examined. The maximum mouth opening at the first examination was 28mm. He received mouth opening training, and at the mental department, the dose of tranquilizer was reduced and he was treated with a muscle relaxant. Presently, the maximum mouth opening has improved to 40mm and his progress is under observation.
