【摘要】：目的探讨颞下颌关节骨关节病(TMJOA)患者在不同骨关节病分期髁突三维影像学特征的差异。方法以2005年马绪臣等提出的骨关节病X线表现分期为标准,将108例TMJOA患者(骨关节病组)的锥形束CT(CBCT)检查结果分为4期,对照组为28例仅存在间隙改变的颞下颌关节紊乱病患者;评价TMJOA CBCT征象不同分期时髁突的矢状面位置,并对2组的髁突水平角进行比较。结果 TMJOA不同分期髁突矢状面位置无统计学差异,但髁突水平角有统计学差异(F=3.872,P=0.005),进一步两两分析表明,第1期髁突水平角低于第2和3期(P=0.027,P=0.000);第2期对照组髁突水平角低于第3期(P=0.004,P=0.047)。结论 TMJOA患者在不同分期时髁突矢状面位置差异不明显,但髁突水平角存在差异,该角度的变化对TMJOA的分期有一定提示意义。
[Abstract]:Objective to investigate the difference of three dimensional imaging features of condyle in different stages of temporomandibular osteoarthropathy (TMJOA). Methods 108 cases of TMJOA (osteoarthropathy group) were divided into 4 stages by conical beam CT (CBCT) according to the X-ray staging of osteoarthropathy proposed by Ma Ogata et al in 2005. The control group consisted of 28 patients with temporomandibular joint disorder with only interspace changes. The sagittal position of condyle in different stages of TMJOA CBCT signs was evaluated and the condylar horizontal angle was compared between the two groups. Results there was no significant difference in sagittal position of condyle in different stages of TMJOA, but there was significant difference in horizontal angle of condylar process (FF3. 872% P0. 005). The condylar horizontal angle of stage 1 was lower than that of stage 2 and 3 (P0. 027), and that of stage 2 of control group was lower than that of stage 3 (P0. 004 and P0. 047). Conclusion there is no significant difference in the sagittal position of condyle in different stages of TMJOA, but there are differences in the horizontal angle of condyle, and the change of this angle may be helpful to the staging of TMJOA.
