摘要 目的探讨磁共振动态扫描技术在颞下颌关节盘移位中的应用效果。方法选择2017年1月至2018年5月本院收治的46例(共92侧)颞下颌关节盘移位患者作为研究对象,所有研究对象均行磁共振动态扫描,观察患者颞下颌关节MRI斜冠状位、斜矢状位图像,并分析张闭口位关节盘的形态及位置变化情况。结果92例关节中34个关节盘形态、位置和信号正常;58个关节盘移位,其中可复性关节盘前移位30个,不可复性关节盘前移位22个,外侧移位2个,内侧移位4个;MRI主要表现为关节盘形态不规则,呈伸长型、折叠型等改变,伴髁突运动异常10例,合并关节积液9例。结论MRI可清楚显示颞下颌关节盘的结构、位置及盘突关系改变情况,可为颞下颌关节盘移位的诊断提供辅助诊断依据。
