Temporohyoid Osteoarthropathy and Hyoid Disease
I was hoping that someone could give me some information about
THO : Temporohyoid Osteoarthropathy and Hyoid Disease. A friend of
mine has a 10 year old TB mix gelding that was just recently
diagnosed with this problem. It was found at a University equine
hospital when he was admitted after having a severe reaction to
ingesting pokeweed. Surgery was recommended. What causes this
problem, and is surgery currative ? What are the dangers of surgery
besides anesthesia ? Any information would be greatly appreciated.
Thanks in advance. Judy

Otitis media/interna* in the equine most commonly is a chronic,
insidious infection with the unique sequella of temporohyoid
osteoarthropathy in some horses. Head shaking may be the only
clinical sign of the early stages of this disease. The arthritic
condition often leads to fusion of the temporohyoid joint with
resultant stress fractures of the petrous temporal bone. When this
occurs, the horse presents as an acute neurologic case with clinical
signs of vestibular and facial nerve dysfunction. Diagnosis,
treatment, and prognosis are discussed. Recognition of this syndrome
is important because many of these horses can be treated successfully
and can return to normal function.
