While the definitive cause is not clearly understood, spontaneous bouts of masticatory myositis can be confirmed with the 2M antibody titers. The prognosis is usually good provided aggressive threapy is started and the animal has a reasonable range of motion. Attempts to force the fibrosed mouth open are discouraged and salvage surgical intervention may be the animal's only hope. Neuropathies include those following trauma, trigeminal neuropathy, and central nervous system disorders. Trauma issues should be obvious based on history and clinical signs.
Prognosis is dependant on the severity and extent of injury.
Occasionally chieloplasty is indicated to help control a disabled tongue. Occasionally the degree of dehydration requires intravenous fluid therapy to restore normal physiology. In any event, hand feeding, elevating food dishes, and time are generally curative. Central nervous system disorders include tumors, encephalitis, and trauma. CT scans reveal space occupying masses that explain the behavior.
