Abstract

Oromandibular dystonia (OMD) is a form of focal dystonia that affects masticatory, lower facial, and lingual muscles. We compared the clinical variables and response to treatment between patients with idiopathic jaw-closure C-OMD (n=11) and jaw-opening dystonia O-OMD (n=12) seen in our Movement Disorders clinic over the last 10 years. The co-existence of dystonia in other regions and sensory tricks were significantly more prevalent in O-OMD (P=0.049 and 0.03, respectively). Male gender, orobuccolingual dyskinesias (facial grimacing, lip biting, tongue dyskinesias, platysma contractions and bruxism) and better response to botulinum toxin injections were more frequent in C-OMD but remained a trend.
