Masticatory Muscle Myopathy in a Dog

Abstract

A 2,5 years old mixed breed male dog presenting complaints of inability to open the mouth, drooling, with no food and water consumption 3 days prior to referral was enrolled in the present article. Dehydration, bilateral severe swelling of the temporal and masseter muscles and constant pytyalism were detected at physical examination. Body temperature was within the reference ranges and neither orthopedic nor neurologic abnormalities were detected. Complate blood cell count did not show abnormalities other than eosinophilia of 2170/ml. Clinic and histopathologic findings indicated masticatory muscle myopathy. Initial treatment included prednisone 1 mg/kg/12h, i.m. and procain peniciline 20000 IU/kg/day, i.m. administrations. Related clinical signs were regressed following 3 days of therapy. The case regained normal jaw motions albeit severe atrophy was evident in masseter and temporal muscles. Almost 2 months later, the case was readmitted with similar symptoms, because of withdrawal of recommended drugs by the owner himself. Supportive therapy included dexamethasone 0.15 mg/kg, p.o. for 15 days . Jaw functions recovered within 4 days and were still normal after six months. As a result, it was concluded that immune-mediated inflammation of muscles of mastication in dogs may be treated with use of steroids for a long period, albeit in case of early withdrawal of therapy, recurrence may observed, following initial recovery swelling and severe atrophy could be developed on masticatory musles whereas this conditon may not limit jaw mobility.
