Abstract
Localized myositis ossificans is a disease with the main feature of formation of heterotropic bone and fibrous tissue involving muscle. It also called traumatic myositis ossificans. Myositis ossificans is likely to occur in the femoral region or brachium but, rarely in the head and neck including the masticatory muscles. It arises from traumatic episodes caused by prolonged mouth opening, surgical procedure, local anesthesia injection. The main clinical feature is the mouth open limitation. The diagnosis of myositis ossificans is usually based on the patient's history, clinical symptoms and on imaging finding. We present the case of patient with localized myositis ossificans of the temporal and lateral pterygoid muscles.
