Abstract

Localized myositis ossificans is a disease with the main feature of formation of heterotropic bone and fibrous tissue involving muscle. It also called traumatic myositis ossificans. Myositis ossificans is likely to occur in the femoral region or brachium but, rarely in the head and neck including the masticatory muscles. It arises from traumatic episodes caused by prolonged mouth opening, surgical procedure, local anesthesia injection. The main clinical feature is the mouth open limitation. The diagnosis of myositis ossificans is usually based on the patient's history, clinical symptoms and on imaging finding. We present the case of patient with localized myositis ossificans of the temporal and lateral pterygoid muscles.

국한성 화골성 근염은 근육내에 섬유조직과 이소성 골이 형성되는 질환으로 외상성 화골성 근염으로도 알려져 있으며 외상, 외과적 술식, 지속적인 자극에 의하여 근육이 골화되는 질환이다. 주로 팔, 다리 근육에서 발생되며, 저작근에서 발생되는 예는 드물다. 저작근에 발생된 경우 주된 임상증상은 개구제한이며 환자는 이환부위의 동통이나 불편함을 호소하기도 한다. 본 연구는 30대 남성이 개구제한을 주소로 내원하여 임상검사와 방사선검사 후 저작근중에서 좌측 측두근과 외측 익돌근에서 발생된 국한성 화골성 근염으로 진단 내려진 증례를 보고하고자 한다.
