Syed Zainal SAJ, Bustaman AF, Sophia AM, Nathan A: Bilateral Temporomandibular Joint Ankylosis with Myositis Ossificans of the muscles of mastication. Mal. J. Oral Maxillofac. Surg. 2020; 18: 16–19.

Abstract: Temporomandibular joint ankylosis is the fusion of mandibular condyle to the glenoid fossa. Myositis Ossificans meanwhile is a rare condition that is characterized by bone depositions in the muscles or soft tissues. Myositis ossificans is benign and a result of heterotopic bone formation in the muscles of mastication. It is an uncommon finding, which produces limitations in the opening of the jaws. This case report presents a case of temporomandibular joint ankylosis with Myositis ossificans of the lateral and medial pterygoid muscles. The present case emphasizes on the treatment of bilateral temporomandibular joint ankylosis and the removal of calcified masses limiting the mouth opening of the patient.
