Abstract

In recent years, injury caused by violence and threat has been gradually increasing, moreover, confinement is a notable event. In this report, we present a case of severe trismus (the inability to normally open the mouth) due to traumatic myositis ossificans associated with confinement and violence. The patient was a 28-year-old man who consulted the Department of Oral and Maxillofacial Surgery Tokyo Women's Medical University Daini Hospital because of severe trismus. He has been confined in an acquaintance's house for 9 days and continuously treated violently. After he escaped, he was transmitted to the Department of Emergency Medicine of our hospital, where remarkable swelling on the left masseter muscle was noted and he was referred to our department. Interincisal distance was 2 mm under his own power and 5 mm under forced opening. Radiographic examinations demonstrated a few calcium deposits in the left masseter muscle. Clinical diagnosis was traumatic myositis ossificans of the muscle. Because of the high level of ALP and the presence of mental instability, we chose to avoid surgery. We facilitated mouth opening using gag and explained a method of practice by himself. He became able to open his mouth over 35 mm after 5 weeks, which seemed to be sufficient for daily life.
