How useful is botulinum toxin (BT) for treating oromandibular dystonia (OMD)?
Background: OMD has an estimated annual incidence of 3.3 to 6.9 cases per one million people and carries with it significant quality-of-life issues due to effects on chewing, swallowing and talking. OMD may be alleviated by sensory tricks including talking, singing, lip biting, tongue posturing and chewing gum. Over the past 20 years, there have been reports of the use of botulinum toxin in the treatment of OMD.
