AB  - INTRODUCTION: The aim of this experimental study was to investigate, under the 
      premise of discectomy, whether damage to either the fibrous layer of the condyle 
      or that of the glenoid fossa, could induce temporomanibular joint (TMJ) 
      ankylosis. And if not, which of the fibrous layer was more important in the 
      genesis of TMJ ankylosis. MATERIALS AND METHODS: Bilateral TMJ surgery was 
      performed in 6 growing Xiao-wei Han sheep. Disk and condylar fibrous layer 
      removal (DCFLR) was performed on the left TMJ, and disk and glenoid fibrous layer 
      removal (DGFLR) was performed on the right TMJ. All animals were sacrificed at 3 
      months postoperatively. The TMJ complexes were examined by histological 
      evaluation. RESULTS: Partial fibrous ankylosis was achieved on the DCFLR side in 
      the 6 sheep at 3 months after surgery. On the DGFLR side, pathologic 
      characteristics of TMJ osteoarthritis could be seen; however, no evidence of 
      ankylosis was observed. The scores of TMJ ankylosis for the DGFLR side were 
      significantly lower than those for the DCFLR side (P<0.05). CONCLUSION: This 
      study demonstrated that removal of the condylar fibrous layer, not the glenoid 
      fibrous layer, combined with discectomy could lead to traumatic TMJ ankylosis.
