Abstract:
Orofacial movement disorders (OMDs) include dystonia, dyskinesia, drug-induced extrapyramidal reactions, and bruxism. The definition, epidemiology, pathophysiology, clinical features, and management are detailed. OMDs are often disabling and affect patients' overall quality of life with pain, difficulty chewing food, speech difficulty, drooling, and social embarrassment. Management involves medications, botulinum toxin injections, and peripheral or central surgery. Botulinum toxin injections are the most effective management, often used in conjunction with medications. Surgery is the last resort for patients who fail to respond to medications or develop resistance to botulinum toxin type A.
