Head Injury and Posttraumatic Oromandibular Dystonia: A Case Report

Abstract

Oromandibular dystonia (OMD) can be described as a focal dystonia which is characterized by repetitive or sustained contraction of various muscles of mastication, tongue, or face resulting in involuntary jaw opening, closing, deflection, retrusion, or a combination of these. Various abnormal movements like tremor, tics, Parkinsonism, chorea, and dystonia may be seen in patients with traumatic brain injury. Tremor and dystonia are the most common movement disorder seen in such cases. The purpose of this presentation is to report a case of posttraumatic OMD in a head injury patient successfully managed by the use of Botulinum Toxin Type-A.
