摘　　要：目的 :探讨颞颌关节骨关节炎 (TMJOA)与颞颌关节内紊乱 (TMJID)的关系。方法 :利用MRI金标准 ,对 44例颞颌关节紊乱病患者 88侧关节完成开闭口T1加权成像 ,观察盘突关系和骨改变。结果 :88个关节中40 .9% ( 3 6/88)表现为TMJID ,13 .6% ( 12 /88)表现为TMJOA ,骨改变的分布情况 :正常盘突关系 (NDCR)关节中 2个 ,破坏和骨赘各 1个 ;可复性关节盘前移位 (ADDR)关节中 3个全部表现为骨破坏 ;不可复性关节盘前移位 (AD DWR)关节中 7个 ,表现为髁状突变平 3个 ;表现为破坏、骨赘、硬化和短小各 1个 ,统计学分析发现TMJOA与TMJID具有显著相关性。结论 :TMJOA的发生与关节结构紊乱显著相关。由于TMJOA可独立于TMJID之外而单独存在 ,目前将TMJOA看作是与TMJID密切相关的另一类疾病较为合适。Objective: To investigate the relationship between osteoarthrosis (OA) and temporomandibular joint internal derangement(TMJID).Method :In order to study the disc-condyle relationship and bone change of the condyle,oblique sagittal T1 weighted MR imaging at closed and open mouth was obtained from 88 joints of 44 patients with TMD.Result:Of 88 joints, 36 joints (40.9%) showed TMJID and 12 joints(13.6%) showed OA. The distribution of OA was as follows: 2 (erosion and spurring) in joints with NDCR, 3 (erosion) in joints with ADDR and 7 (3 flattening, erosion, spurring, eburnation and pointed condyle) in joints with ADDWR. Statistical analysis showed significant correlation between OA and TMJID (P<0.05).Conclusion :The development of OA is closely correlated with TMJID.Currently, it is suitable to consider OA as another disease which is independent of TMJID.
