Abstract

Dystonia is the manifestation of involuntary lasting severe muscle contractions, which lead to rhythmic and atypical movements in different parts of the body. Dystonia is the most common movement disorder next to Parkinson’s disease (PD) and essential tremor (ET). Oro Mandibular Dystonia (OMD) is considered as a focal dystonia involving mouth, jaw, and tongue, manifested by involuntary muscle contractions producing repetitive, patterned movements of the involved structures. The diagnosis of OMD is purely clinical and is to be differentiated thoroughly from the conditions mimicking the signs. Since it presents in various forms and severities it further renders the management a multidisciplinary approach with variable treatment outcomes. The following is a clinical diagnostic case report of oromandibualar dystonia with presenting signs and symptoms, history and examination characteristic of the condition.
