【摘要】：目的：研究颞下颌关节可复性关节盘前移位(Anterior Disc Displacement with Reduction, ADDR)患者经过保守治疗,关节弹响症状消失前后关节盘的位置变化,探讨关节弹响与关节盘位置的关系。方法：选取27例要求治疗颞下颌关节弹响的患者,其中49侧关节诊断为ADDR,采用口颌系统功能锻炼治疗,分别行治疗前和经治疗弹响消失后双侧颞下颌关节MRI扫描,并录像记录患者开闭口时下颌运动状态。选取TMJ斜矢状位MRI采用钟点法评价关节盘位置,对所记录数据采用SPSS13.0软件进行t检验统计学分析。结果：治疗前关节盘位置为28.15°±10.92°,其中4侧关节有弹响症状但盘位正常,45侧关节有弹响症状且关节盘前移位,关节盘前移率为91.84%。经治疗弹响消失后关节盘位置为28.64°±6.65°,治疗前评价为盘前移位的45侧关节在治疗后仍为盘前移位。治疗前与治疗后对比,关节盘位置无显著性差异(P0.05)。结论：颞下颌关节弹响与关节盘的位置是否前移无关。
[Abstract]:Objective: to study the changes of the position of the articular disc before and after conservative treatment in the patients with Anterior disc displacement with reduction (ADDRs), and to explore the relationship between the joint elastic response and the position of the articular disc. Methods: Twenty-seven patients with temporomandibular joint (TMJ) bounce were selected, 49 of them were diagnosed as ADDR.The patients were treated with oral and maxillary system functional exercise. MRI scans of bilateral temporomandibular joint were performed before and after the treatment. The mandibular movement was recorded by video recording. TMJ oblique sagittal MRI was used to evaluate the position of articular disc by hour method, and the recorded data were analyzed by t test with SPSS 13.0 software. Results: the position of articular disc before treatment was 28.15 掳卤10.92 掳, of which 4 joints had bounce symptoms but 45 joints in normal disc position had elastic symptoms and anterior disc displacement. The anterior displacement rate of disc was 91.84%. After treatment, the position of articular disc was 28.64 掳卤6.65 掳. 45 joints with anterior disc displacement were still anterior disc displacement after treatment. There was no significant difference in the position of articular disc before and after treatment (P0.05). Conclusion: the response of temporomandibular joint is not related to the position of disc.
