During a five-year period, a total of 150 patients (131 girls and 19 boys) with an average age of 14 years (range 7-16 years), with signs and symptoms of temporomandibular joint dysfunction were referred for imaging in the diagnostic radiology department. These patients were evaluated by multidirectional tomography to both joints, arthrography, computed tomography (CT), or magnetic resonance (MR) of one or both joints. Fifty-six (37 percent) of the 150 patients had plain tomographic, CT or MR evidence of degenerative arthritis of one or both sides (18/150 12 percent with bilateral degenerative joint disease). Internal derangements of the TMJ related to meniscal displacements and dysfunction were detected in 128 patients (85 percent). Twenty-nine patients (29/150: 20 percent) suffered from bilateral internal derangements. This clinical study demonstrates that internal derangements do occur in the pediatric age-group: the high percentages of both internal derangements and degenerative joint disease suggest a cautious clinical acceptance of imaging for internal derangements in the young patient. This reluctance to study these patients should be minimized by the new, noninvasive imaging modality available in magnetic resonance.
在五年期间，共有150例颞下颌关节功能紊乱体征和症状的患者（131名女孩和19名男孩）被转诊至诊断放射科进行影像学检查，平均年龄14岁（范围7 - 16岁）。这些患者接受了双侧关节的多向断层摄影、关节造影、计算机断层扫描（CT）或单关节或双关节的磁共振（MR）检查。150例患者中有56例（37%）有一侧或双侧退行性关节炎的平片断层摄影、CT或MR证据（18/150，12%为双侧退行性关节病）。128例患者（85%）检测到与半月板移位和功能障碍相关的颞下颌关节内紊乱。29例患者（29/150：20%）患有双侧关节内紊乱。这项临床研究表明，关节内紊乱确实发生在儿童年龄组：关节内紊乱和退行性关节病的高比例表明临床对年轻患者关节内紊乱成像应持谨慎态度。磁共振这种新的非侵入性成像方式应尽量减少对这些患者进行检查的顾虑。
