摘要
目的：研究颞下颌关节骨关节病（ＴＭＪＯＡ）对关节盘的影响。方法：选择健康成年无角努比羊１２只，随机分为对照组（２只）和实验组（１０只），关节上腔内注射１％胶原酶建立ＴＭＪＯＡ动物模型，分别于实验后１、２、３、４、６月处死山羊，结合组织病理学改变，观测病变关节盘位置改变情况。结果：在ＯＡ病变基础上存在肯定的关节盘位置改变。结论：本实验条件下，颞下颌关节盘移位可能是ＯＡ病变发展到一定阶段时的继发改变。
Objective:To learn the changes of TMJ disc positions under the influences of TMJ Osteoarthrosis(TMJOA). Methods: The TMJOA experimental animal model was established by12 goats. The TMJ disc positions were observed and recorded at different intervals, (1 month, 2 months, 3 months, 4 months and 6 months) then the pathological changes of TMJ specimens were also studied.Results: Significant anteromedial shift of TMJ disc position was observed in some certain TMJOA phases and became more obviously along with the disease progress.Conclusion: The shift of TMJ disc may be the secondary change of TMJOA.
