Mandibular condylectomy successfully treated a horse with temporomandibular joint ankylosis. This surgical intervention improved chewing function and resolved significant weight loss in the animal.

Area of Science:

  • Veterinary Surgery
  • Equine Medicine
  • Temporomandibular Joint Disorders

Background:

  • A horse presented with a history of recurrent facial suppuration and unilateral temporomandibular joint (TMJ) ankylosis.
  • The condition significantly impaired masticatory function, leading to progressive weight loss.

Observation:

  • The unilateral TMJ ankylosis restricted jaw movement, causing difficulty in prehending and chewing food.
  • Intermittent purulent discharge from a facial wound indicated a chronic inflammatory or infectious process associated with the joint pathology.

Findings:

  • Surgical treatment via mandibular condylectomy was performed to address the TMJ ankylosis.
  • The procedure effectively restored normal temporomandibular joint mobility and function.

Implications:

  • Mandibular condylectomy is a viable surgical option for managing severe temporomandibular joint ankylosis in horses.
  • Successful treatment can restore masticatory efficiency, prevent further weight loss, and improve the overall health and welfare of affected equines.
