The purpose of this study was to investigate the effect of costochondral grafts in the temporomandibular joint (TMJ) in sheep. Five pure-bred adult Merino sheep were used. The condyle alone was resected and replaced with a costochondral graft from the 13th rib. The sheep were killed 3 months after operation. The range of jaw movements before and after operation and at death were recorded. The joints were examined radiologically, macroscopically, and histologically. A new condylar head with normal configuration and function developed. Histologically, the chondrocytes were arranged in a fashion similar to that of a normal joint. All inferior joint spaces showed fibrous adhesions between the condylar head and disc. This study showed that, when such grafts are used to replace the condyle in an otherwise normal sheep TMJ, they fused to the ramus and reconstituted a nearly normal, fully functional joint.
