Condylectomy and menisectomy were performed in left TMJ of 14 rabbits, of them, 7 were treated with periosteal interposition and 7 without. Sixteen weeks after operation, condylar cartilage of the right side were studied and compared with 7 normal rabbits by means of histology and histochemistry. The results show that an operation of high condylectomy and menisectomy with or without interposition on one side of TMJ will result in degenerative changes in the other side (non-operated side). The degenerative changes in the rabbits without any interposition are more serious than those with periosteal interposition.
对14只家兔的左侧颞下颌关节进行髁突切除术和半月板切除术，其中7只进行骨膜植入，7只未进行。术后16周，通过组织学和组织化学方法研究右侧髁突软骨，并与7只正常家兔进行比较。结果表明，一侧颞下颌关节进行高位髁突切除术和半月板切除术（无论是否植入）会导致另一侧（未手术侧）发生退行性改变。未进行任何植入的家兔的退行性改变比进行骨膜植入的家兔更严重。
