Mandibular condylectomy in a standing horse for treatment for osteoarthritis of the temporomandibular joint

Abstract

Summary An I rish S port H orse mare presented for evaluation and treatment of inability to masticate effectively with subsequent severe weight loss. A slowly expanding, firm, nonpainful mass was noted at the left temporomandibular joint. Radiographic examination revealed extensive osteoarthritic changes of this joint. Due to the age and debilitated condition of the horse, along with financial constraints on the owner's behalf, the decision was made to perform a mandibular condylectomy as a standing procedure using sedation and local and regional anaesthesia techniques. The mare tolerated the procedure very well and post operatively improved significantly.
