摘要
【目的】研究颞下颌关节紊乱病(TMD)的MRI表现与颞下颌关节疼痛的关系,探讨MRI在TMD诊断和治疗中的价值。【方法】对30例具有疼痛主诉的TMD患者的60侧颞下颌关节(TMJ)行开、闭口冠状位和矢状位T1加权、T2加权和质子加权扫描。【结果】MRI观察到37个疼痛关节中,发现关节盘移位34个(91.9%),关节盘变形33个(89.2%),关节渗液31个(83.8%);23个非疼痛关节中,关节盘移位12个(52.2%),关节盘变形3个(13%),关节渗液1个(4.5%)。经统计学分析,疼痛与关节盘移位、变形和关节渗液的出现有关系(P<0.01)。【结论】MRI能清楚显示TMJ关节盘及周围组织变化,能反映TMJ的变化与疼痛的关系,在TMD的诊断和治疗方面均具有重要价值。
[Objective]To study the relationship between MRI findings and joint pain in patients with temporomandibular disorders（TMD） and investigate the value of MRI in the diagnosis and treatment of the disease. [Methods]Sixty joints of 30 TMD patients who complained of pain were examined by MRI. [Results] MRI findings showed 34 （91.9%）of the 37 painful joints with disk displacement, 33（89.2%） with disk deformities, and 31（83.8%） with extravasate. The temporomandibular joint pain showed significant relationship with disk displacement, disk deformities and extravasate （ P〈0.01）. [Conclusion]MRI can be used to investigate the change of temoromandibular joint. It is very important for the diagnosis and treatment of TMD.
