Abstract

Myositis ossificans traumatica is a rare condition in which causes restriction of mandibular movement. In this entity, temporomandibular joint is depleted of any problems; although all the patients have the history of trauma to the mandible and the face. Myositis ossificans traumatica can involve other parts of the body like femoral region with higher incidence in compare to the maxillofacial area. Blunt trauma to the head and neck causes muscle contusion injury, hematoma formation in the injured muscles or nearby soft tissues. Calcification of hematoma and heterotopic bone formation in the muscle, soft tissue, or near bony structures causes progressive decrease in mouth opening. Surgical removal of calcified body has been the only and one method for treatment of this disorder but rate of recurrence is high in the literature. The authors want to introduce 2 new cases of myositis ossificans traumatica, and then discuss about etiology and different treatment modalities. © 2021 Lippincott Williams and Wilkins.
