猪自体肋骨－肋软骨移植颞颌关节成形术模型的建立

Establishment of Animal Model of TMJ Arthroplasty with Autogenous Costochondral Grafts in Pigs

以猪为实验对象，以自体肋骨－肋软骨移植做颞颌关节成形术，其中包括肋骨－肋软骨切取术、单侧下颌骨髁状突切除术、以及自体肋骨－肋软骨移植重建切除之髁突，完成髁突置换式的颞颌关节成形术。结果表明所建立的动物模型可靠，是研究颞颌关节成形术较理想的实验手段。

The arthroplasty of temporomandibular joint (TMJ) by transplanting an autogenous costochondral graft in juvenile male pigs was described, which includes the removeal of autogenous costochondral segment, the unilateral condylectomy and thereconstructioh. of the missing condyle. The established animal model might provide an ideal means for the study of TMJ arthroplasty.
