31 patients with clinically diagnosed dysfunction of the temporomandibular joint (TMJ) were examined by magnetic resonance imaging (MRI; 1.5 Tesla, TR/TE 600/30) in closed and open mouth position and functional arthrography with digital image recording.
Both methods agreed in the evaluation of the disc position. In 23 joints with displaced disc reposition was found in 11 cases and in 14 cases using MRI or arthrography, respectively. MRI proved to be superior in the diagnosis of sideways disc rotations. Joint hypermobility, eccentric disc displacement (n = 4) and perforation (n = 3) were shown by functional arthrography. Due to the good demonstration of osseous, muscular and discoligamentous structures, MRI as a noninvasive imaging modality is the method of choice for TMJ evaluation. Arthrography can be advantageous in complex functional disturbances or if MRI and clinical findings are inconclusive. The clinical diagnosis of disc displacement was found to be accurate in only 68% of the cases.
对31例临床诊断为颞下颌关节(TMJ)功能障碍的患者,在闭口和开口位时采用磁共振成像(MRI;1.5特斯拉,TR/TE 600/30)进行检查,并采用数字图像记录的功能关节造影术。
两种方法在评估盘状位置方面结果一致。在23个关节盘移位的关节中,分别使用MRI或关节造影术,在11例和14例中发现关节盘复位。MRI在诊断关节盘侧向旋转方面被证明更具优势。功能关节造影显示关节活动过度、关节盘偏心移位(n = 4)和穿孔(n = 3)。由于MRI能很好地显示骨、肌肉和盘韧带结构,作为一种非侵入性成像方式,它是评估TMJ的首选方法。关节造影术在复杂功能障碍或MRI及临床检查结果不明确时可能具有优势。发现仅68%的病例中关节盘移位的临床诊断是准确的。
