摘要
目的研究145例颞下颌关节紊乱病(TMD)患者的磁共振成像(MRI)影像学表现,为临床治疗提供依据。方法利用MRI对145例TMD患者的290侧关节完成开闭口斜矢状位、闭口斜冠状位T1/T2加权成像,观察盘突关系,髁突骨质改变,关节腔积液,关节盘形态改变等情况,并进行分类统计。结果 MRI检查结果显示:37.2%患者双侧TMD病变,71%患者伴有不可复关节盘前移位,10.3%患者伴有可复性关节盘前移位,6.9%患者伴有髁突骨质改变,4.8%患者伴关节腔积液,52.4%患者伴关节盘明显变形。结论 TMD患者中以关节盘不可复性前移位最为常见,提示正常盘突关系的重要性。MRI可以为临床医师提供可靠的影像学诊断依据。
