1/7. myositis ossificans traumatica of the temporal muscle: a case report.

    myositis ossificans traumatica (MOT) is a pathological condition characterized by extraskeletal formation of bony tissue, induced by violent or repeated trauma. Reports of this pathology occurring in the region of the head and neck are rare, and even more so in the muscles of mastication. We present the case of patient with MOT of the temporal muscle, the etiology of which seems to be related to traumatic manipulations during dental treatment. A review of the literature is presented and the surgical approach, which resolved this case is discussed.

2/7. Clinicopathologic conference: trismus following dental treatment.

    myositis ossificans traumatica is a rare clinical entity in the maxillofacial region. We present a case of myositis ossificans traumatica of the temporalis muscle following dental treatment in the form of a clinicopathologic conference. A review of the literature supporting our findings is provided.

3/7. Post-traumatic severe trismus caused by impairment of the masticatory muscle.

    Restriction of the mouth opening from a pathologic condition outside the temporomandibular joint is called a pseudo- or extra-articular ankylosis. The authors report two cases of severe post-traumatic pseudoankylosis. One case showed fibrous degeneration of the bilateral masseter muscles without a facial bone fracture, which caused severe trismus, a mouth opening of less than 2 mm, and gradually appeared after blunt injuries to the face. The other was a rare case accompanied with the bone formation in the masseter muscle and was diagnosed as myositis ossificans traumatica, which also presented as severe trismus, with a maximal mouth opening of 5 mm after facial violence. Both were surgically treated with dissection of the affected muscles. In addition, a hemicoronoidotomy was performed in the case of myositis ossificans traumatica. Although a conservative therapy with physical rehabilitation is the basic policy for the management of pseudoankylosis of the temporomandibular joint, a surgical treatment should be considered when the origin of the problems is an osteogenic character or severe extra-articular ankylosis resistant to conservative therapy before completion of true temporomandibular joint ankylosis.

4/7. myositis ossificans of medial pterygoid muscle. A cause for temporomandibular joint ankylosis.

    An unusual case of myositis ossificans of the medial pterygoid muscle has been discussed. It is important to know the exact cause of the temporomandibular joint ankylosis, for successful treatment. Computed tomographic scan and panoramic radiographs are essential diagnostic aids for evaluating conditions such as myositis ossificans. myositis ossificans can be one of the causes of extra-articular temporomandibular joint ankylosis.

5/7. Fibrodysplasia ossificans progressiva. An unusual cause of restricted mandibular movement.

    A 9-year-old girl is presented who was initially misdiagnosed and finally diagnosed with fibrodysplasia ossificans progressiva only after presentation with progressive limitation of her mouth opening. The clinical, histopathological, and molecular biological aspects of this uncommon disorder will be discussed. Furthermore, dental and surgical guidelines will be described.

6/7. trismus and multifocal soft tissue ossification. A presentation of fibrodysplasia ossificans progressiva?

    A 21-year-old female patient presented with trismus, initially diagnosed as related to pericoronitis. Computed tomography demonstrated heterotopic soft tissue ossification involving both medial pterygoids which was later followed by similar features in the submandibular muscles and right quadriceps. A variant of fibrodysplasia ossificans progressiva was considered the likeliest diagnosis. The computed tomographic features of the condition and the importance of early diagnosis are stressed.

7/7. trismus. An unusual sign in polymyositis.

    Neuromuscular disease is an unusual cause of trismus. However, we describe two patients with severe polymyositis who had difficulty opening their mouths during the acute phase of the illness. electromyography demonstrated involvement of the masseters, and there was no evidence of myasthenia. The mechanism appeared to be decreased elasticity of the masseter because of inflammation, edema, and perhaps contractures.
