Four Macaca fascicularis monkeys underwent bilateral temporomandibular joint surgery including disc removal, condyle recontouring and disc replacement using autogenous auricular cartilage grafts. One side was treated with the cartilage graft alone while the other side was treated with a cartilage graft combined with a temporarily implanted 0.02 inch dacron-reinforced silastic sheet. The silastic sheeting was removed at twelve weeks after the initial surgery. The monkeys were sacrificed at fourteen, twenty-four, thirty-six and fifty-two weeks after the initial disc removal and cartilage grafting. The joints treated with cartilage grafts alone showed significant fibrous connective tissue adhesions which had formed between the inferior surface of the graft and the articulating surface of the condyle. In the joints treated with a cartilage graft and silastic sheeting a joint space was clearly maintained between the cartilage graft and condylar surface without the formation of fibrous connective tissue adhesions. It appears that temporary implantation of a thin silastic sheet combined with autogenous cartilage grafting may prevent the formation of fibrous connective tissue adhesions within the joint.
对4只食蟹猴进行了双侧颞下颌关节手术，包括摘除关节盘、修整髁突以及使用自体耳廓软骨移植物进行关节盘置换。一侧仅用软骨移植物治疗，另一侧则用软骨移植物联合临时植入的0.02英寸涤纶增强硅橡胶片进行治疗。硅橡胶片在初次手术后12周取出。在初次摘除关节盘和植入软骨移植物后的14周、24周、36周和52周对猴子实施安乐死。仅用软骨移植物治疗的关节显示，移植物下表面与髁突关节面之间形成了明显的纤维结缔组织粘连。在用软骨移植物和硅橡胶片治疗的关节中，软骨移植物与髁突表面之间明显保持了关节间隙，未形成纤维结缔组织粘连。似乎临时植入薄硅橡胶片联合自体软骨移植可防止关节内纤维结缔组织粘连的形成。
