Is masticatory myositis fatal in dogs? Masticatory myositis can be fatal as the dog cannot open its mouth to eat or drink properly. If the disease goes untreated or it has progressed to the point that most of the muscle fibers of the jaw have been replaced by fibrous tissue, this disease is not curable.
What does masticatory myositis look like? How is MMM diagnosed? A dog’s inability to open his mouth, inability to eat, swollen chewing muscles, and excruciating face pain are symptoms of MMM. A blood test will diagnose MMM.
How quickly does MMM progress in dogs? In the study, MMM generally carried a favorable prognosis when treated promptly with immunosuppressive doses of prednisone. Dogs typically regained normal masticatory function within 4 weeks of treatment, although 27% of affected dogs experienced relapse that resolved with continued glucocorticoid therapy.
Is masticatory muscle myositis painful? That is often what happens with an autoimmune disorder called masticatory muscle myositis (MMM) that affects the jaw muscles, causing pain and dysfunction. Swollen, painful masticatory (chewing) muscles and an inability to open the mouth (trismus) are clinical signs of the disorder.
