Oromandibular dystonia is a focal neurological movement disorder characterized by involuntary sustained and often painful muscle contraction, usually producing repetitive movements or abnormal positions of the mouth, jaw and.or tongue. Patients suffering from oromandibular dystonia often experience difficulties in chewing, swallowing and speaking, resulting from the impairment of mandibular movements. At present there is no etiologic treatment for oromandibular dystonia, because the pathophysiology of primary and focal dystonia is still incompletely understood. Many treatments such as medication, behavioral therapy, surgery are suggested to decrease the involuntary movements. But these success rates are relatively low and they have a lot of complications. many studies suggested that chemodenervation with botulinum toxin is the most effective treatment for oromandibular dystonia. We reported the 2 cases which were treated oromandibular dystonia with botulinum toxin and reviewed the orofacial movement disorders(especially oromandibular dystonia) and botulinum toxin treatment for oromanfibular dystonia.
