Mandibular Condylectomy Effects in Normal Dogs

Abstract

Mandibular condylectomy and meniscectomy were performed unilaterally on six dogs and bilaterally on six dogs. All six dogs that underwent unilateral condylectomy functioned normally. Bilateral condylectomy caused temporary malocclusion in five of six dogs. At necropsy one to six months following surgery, a fibrous pseudoarthrosis had formed. One dog that underwent bilateral condylectomy had significant loss of maximal mouth opening three months after surgery. Good functional use of the mandible was obtained with unilateral and bilateral condylectomy.
