Myositis ossificans traumatica of masticatory musculature: A case report and literature review

Myositis ossificans traumatica of the medial pterygoid

“…RATTAN et al 11 documented a case in which the buccal pad of fat was used as an interpositional material to treat MOT of the medial pterygoid. KIM et al 8 presented a case in which abdominal fat was harvested and placed as a graft; there was partial relapse within a few months.…”

Myositis ossificans traumatica of the medial pterygoid muscle: a case report

“…Plezia et al reported the treatment of 14 cases in the literature and found that the prognosis is generally good, although some lesions presented recurrence. A period of follow-up before the treatment is recommended, but some authors believe that early intervention is preferable (9). Also, non-surgical therapy must be attempted.…”

“…It is believed that many of the lesions will regress over time (5). Regardless, many suggest that simple excision is curative and that recurrence is rare (9). Some authors insist that early surgical intervention (within 3 to 6 weeks post-injury) is ideal for curative excision (10).…”

“…Some authors insist that early surgical intervention (within 3 to 6 weeks post-injury) is ideal for curative excision (10). However, others have stated that recurrence of the lesion is common if removed at an early stage (9). Another author recommends that surgery should not be contemplated unless the lesion does not regress or it becomes a functional handicap because 35% of cases have been reported to spontaneously resolve over a period of several months (11,12).…”

La myosite ossifiante du muscle temporal

“…L'interrogatoire retrouve parfois la notion de traumatisme violent, mais le plus souvent il s'agit de microtraumatismes répétés. Plusieurs théories ont été proposées afin d'expliquer le mécanisme de cette ossification : une organisation et une ossification réactive d'un hématome intramusculaire posttraumatique, une métaplasie du tissu conjonctif interstitiel, une métaplasie du fibrocartilage, ou encore un échappement intramusculaire de cellules ostéoblastiques suite à un traumatisme du périoste [3]. Le symptôme révélateur est la limitation de l'ouverture buccale, associée à une douleur souvent aiguë [1].…”
