The role of the disk in sheep temporomandibular joint ankylosis
Objective. The purpose of this study was to determine the role of the disk in intraarticular ankylosis of the temporomandibular joint. Study design. Twelve adult sheep were divided into 2 groups. In group 1, removal of the temporal and condylar articular surfaces was performed on the right temporoma...

| description | Objective. The purpose of this study was to determine the role of the disk in intraarticular ankylosis of the temporomandibular joint.
Study design. Twelve adult sheep were divided into 2 groups. In group 1, removal of the temporal and condylar articular surfaces was performed on the right temporomandibular joint and the disk was maintained; in group 2, removal of the articular surfaces and diskectomy were performed on the right temporomandibular joint. One sheep from each group was killed just after surgery and 5 sheep from each group were killed at 3 months. The joints were examined radiologically, macroscopically, and histologically. The range of jaw movements was recorded preoperatively and at sacrifice.
Results. Each of 2 sheep in group 2 had lost 4% of their body weight by 3 months; all of the other sheep maintained or increased their weight. The range of jaw motion to the right was significantly lower in group 2 than in group 1 (
P < .01). In group 1, fibrous repair of the articular surface and regeneration of the condylar head was seen. In group 2, each of the joints showed a total fibrous ankylosis with some calcification. There was a statistically significant difference in radiologic score between the groups (
P < .0001). Histologic scores for group 1 demonstrated significantly lower scores on the degree of ankylosis scale and degree of calcification scale (
P < .0001).
Conclusions. This study showed that the presence of the disk prevented the development of fibrous intraarticular ankylosis of the temporomandibular joint.
