Nine cases of unilateral internal derangement of TMJ indicated for surgical intervention, were selected for this study. The affected joints were imaged by MRI presurgically. The non-affected joints were also imaged as controls. MRI findings were correlated with intraoperative surgical findings. The results were absolutely accurate as regards degenerative joint pathosis and capsular rupture, and with high degree of accuracy (85.7%) in detection of disc displacement. Two cases of disc perforation were not detected by MRI. The results were promising and encouraging the use of this noninvasive imaging technique as presurgical aid in TMJ disorders.
本研究选取了9例因颞下颌关节单侧内紊乱而需进行手术干预的病例。术前对患侧关节进行了磁共振成像（MRI）检查。作为对照，也对未受影响的关节进行了成像。MRI检查结果与术中手术发现进行了对比。在退行性关节病变和关节囊破裂方面，结果绝对准确，在检测盘状移位方面具有高度准确性（85.7%）。有2例盘状穿孔未被MRI检测到。结果令人鼓舞，促使人们在颞下颌关节疾病的术前辅助诊断中使用这种无创成像技术。
