Abstract

A 8-year-old, castrated male Maltese with difficulty in opening his mouth was presented. Masticatory muscle myositis (MMM) was diagnosed by 2M antibody test. After treatment of MMM with corticosteroids, range of jaw motion improved and was almost normal at 5 months. In dogs with MMM, early detection and aggressive immunosuppressive therapy are required to improve the prognosis.

8년령 중성화 수컷 말티즈가 입을 열기 어려운 증상으로 내원하였다. 2M 항체 검사를 통해 저작근염을 진단하였다. 코르티코스테로이드로 처치 후 턱관절의 가동범위가 증가하였고, 처치 5개월 후에는 거의 정상으로 돌아왔다. 저작근염이 발생한 개에서 초기 발견 및 적극적인 면역억제 치료는 예후 향상을 위해 필요한 것으로 사료된다.
