Temporohyoid Osteoarthropathy

Temporohyoid osteoarthropathy and accompanying fractures of these bones is a common cause of unilateral facial paralysis and/or vestibular disease in adult horses. Approximately 50% of horses recover following medical treatment with antibiotics and antiinflammatory drugs. A ceratohyoidectomy is recommended to prevent additional fractures and recurrence of clinical signs. Exposure keratitis and keratoconjunctivitis sicca are frequent complications to facial nerve paralysis, and partial tarsorrhaphy is helpful in preventing these complications.
