摘要:: 目的：研究颞下颌关节可复性盘前移（ADDWR）患者的磁共振（MR）成像表现。方法：纳入颞下颌关节ADDWR患者55例作为观察组，另纳入30例牙齿排列整齐的健康志愿者作为对照组。所有研究对象均接受MR成像检查，记录颞下颌关节ADDWR患者关节盘前移程度，比较不同严重程度患者关节盘形态和关节渗出情况。结果：55例颞下颌关节ADDWR患者中，轻症35例，重症20例。对照组、轻症组及重症组关节盘形态分型比较，差异有统计学意义（P<0.05）。3组对象颞下颌关节渗出情况比较，差异有统计学意义（P<0.05）。不同程度关节渗出患者视觉模拟评分法（VAS）评分差异有统计学意义（P<0.05）。3组对象关节盘长度差异有统计学意义（P<0.05）。轻度组关节盘前移度较重症组显著减轻，差异有统计学意义（P<0.05）。结论：MR有助于颞下颌关节ADDWR患者病情判断，可为临床治疗提供依据。

Abstract:: Abstract: Objective To study the magnetic resonance (MR) imaging findings in patients with temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDWR). Methods Fifty-five patients with TMJ ADDWR were included as observation group, and another 30 healthy volunteers with orderly teeth arrangement were selected as control group. All subjects underwent MR imaging. The degrees of anterior disc displacement in patients with TMJ ADDWR were recorded. The articular disc morphology and joint effusion of patients with TMJ ADDWR of different severity were compared. Results There were 35 mild cases and 20 severe cases among 55 patients with TMJ ADDWR. The morphological classification of articular disc was obviously different among control group, mild group and severe group, with statistical differences (P<0.05). Significant differences were found in TMJ effusion, visual analogue scale score and the length of articular disc among 3 groups (P<0.05). The anterior disc displacement in mild group was significantly less than that in severe group, with statistical differences (P<0.05). Conclusion MR is helpful to the judge the condition of patients with TMJ ADDWR, thereby providing a basis for clinical treatment.
