抄録

Ectopic calcification involves calcium deposition in soft tissues and can occur in subcutaneous, acromioclavicular joint, and intramyocardial tissues. We describe our experience with a rare case of jaw trismus caused by an isolated calcified mass in the temporal muscle and a hyperplasia-like lesion of the mandibular coronoid process. The patient was a 68-year-old woman. Radiographic examination revealed a hyperplasia-like region in the left mandibular coronoid process and an isolated impermeable mass in the temporal muscle. Coronoidectomy and removal of the isolated mass were performed through an intra-oral approach under general anesthesia. The isolated hard tissue consisted of many tubercles including calcification and cartilage-like tissue. The hyperplasia-like region of the mandibular coronoid process also consisted of calcified tubercles. Cartilage and fibrous bone-like tissue were found in peripheral areas of the calcification at the border of the normal bone. After the coronoidectomy, jaw trismus improved, and no recurrence has occurred.
