Oromandibular Dystonia-Related Temporomandibular Joint Osteoarthritis: A Case History Report
Abstract:
Dystonia affecting the perioral and pharyngeal regions is called oromandibular dystonia (OMD). OMD can affect the jaw muscles and may cause trismus, mouth-closing disturbance, tooth wear/loss, and damage to the oral soft tissues and temporomandibular joint (TMJ). This case history reports a case of jaw-closing OMD accompanied by trismus-related TMJ osteoarthritis (OA). In the present case history, treatment for OMD was started as soon as the diagnosis of jaw-closing OMD was established, and dental treatment intervention for preventing its development or progression was considered at the same time.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
