摘要
目的:探讨MRI诊断颞下颌关节损伤的应用价值。材料和方法:对30例颞下颌关节损伤患者于外伤后3～20天内行颞下颌关节MRI检查,MRI扫描序列包括闭口斜矢状位T1WI、PDWI、斜冠状位T1WI、T2WI,张口斜矢状位T1WI、PDWI。由两位资深放射科医师分析MRI表现。结果:30例共60个颞下颌关节中发现18个髁状突骨折,9个骨损伤,29个关节盘移位,26个关节囊积液、积血。结论:MRI能很好的显示颞下颌关节的骨折、骨损伤以及关节盘与关节囊损伤情况,是颞下颌关节损伤的重要检查与评价手段,具有很高的临床应用价值。
Purpose：To investigate the value of MRI in diagnosing traumatic temporomandibular joint.Materials and Methods：MRI were performed in 30 patients with the temporomandibular joint injuried 3～20 days ago.Oblique sagittal T1WI and PDWI,oblique coronal T1WI and T2WI in close mouth position,oblique sagittal T1WI and PDWI in open mouth position were obtained.The MRI findings were analyzed by two senior radiology doctors.Results：In 60 TMJs of 30 patients,MRI findings including mandibular condyle fracture of 18 joints,mandibular condyle and articular tubercle impairment of 9 joints,TMJ disk displacement of 29 joints,and joint effusion or hemarthrosis of 26 joints.Conclusion：MRI can clearly display the fracture and impairment of the TMJ,so that it is very useful for the diagnosis of traumatic TMJ.
