To determine the prevalence of temporomandibular joint internal derangement in patients with signs and symptoms of craniomandibular disorders, bilateral imaging was performed in a consecutive series of 115 patients with signs and symptoms of craniomandibular disorders. Ninety patients (78%) had different stages of unilateral or bilateral internal derangement, and 25 patients (22%) had normal temporomandibular joints bilaterally. Out of 230 joints, 60 showed disk displacement with reduction, 8 showed disk displacement without reduction, and 29 showed disk displacement without reduction associated with anthrosis. The study indicates that almost 80% of patients with signs and symptoms of craniomandibular disorders have different forms of internal derangement.
为确定患有颅下颌疾病体征和症状的患者颞下颌关节内紊乱的患病率，对连续的115例患有颅下颌疾病体征和症状的患者进行了双侧影像学检查。90例患者（78%）有单侧或双侧不同阶段的内紊乱，25例患者（22%）双侧颞下颌关节正常。在230个关节中，60个显示可复性盘移位，8个显示不可复性盘移位，29个显示不可复性盘移位伴关节病。该研究表明，几乎80%患有颅下颌疾病体征和症状的患者有不同形式的内紊乱。
