Idiopathic condylar resorption is a poorly understood progressive disease that affects the TMJ and that can result in malocclusion, facial disfigurement, TMJ dysfunction, and pain. This article presents the diagnostic criteria for idiopathic condylar resorption and a new treatment protocol for management of this pathologic condition. Idiopathic condylar resorption most often occurs in teenage girls but can occur at any age, although rarely over the age of 40 years. These patients have a common facial morphology including: (1) high occlusal and mandibular plane angles, (2) progressively retruding mandible, and (3) Class II occlusion with or without open bite. Imaging usually demonstrates small resorbing condyles and TMJ articular disk dislocations. A specific treatment protocol has been developed to treat this condition that includes: (1) removal of hyperplastic synovial and bilaminar tissue; (2) disk repositioning and ligament repair; and (3) indicated orthognathic surgery to correct the functional and esthetic facial deformity. Patients with this condition respond well to the treatment protocol presented herein with elimination of the disease process. Two cases are presented to demonstrate this treatment protocol and outcomes that can be achieved. Idiopathic condylar resorption is a progressive disease that can be eliminated with the appropriate treatment protocol.
特发性髁突吸收是一种了解甚少的进行性疾病，会影响颞下颌关节，并可导致错牙合、面部畸形、颞下颌关节功能障碍和疼痛。本文介绍了特发性髁突吸收的诊断标准以及针对这种病理状况的新治疗方案。特发性髁突吸收最常发生在少女中，但可发生于任何年龄，尽管40岁以上者很少见。这些患者具有共同的面部形态，包括：（1）高咬合平面角和下颌平面角；（2）下颌骨逐渐后缩；（3）伴有或不伴有开牙合的安氏II类错牙合。影像学检查通常显示髁突吸收变小以及颞下颌关节盘脱位。已制定了一种特定的治疗方案来治疗这种疾病，包括：（1）切除增生的滑膜和双板组织；（2）关节盘复位和韧带修复；（3）进行必要的正颌手术以纠正功能性和美观性面部畸形。患有这种疾病的患者对本文介绍的治疗方案反应良好，疾病进程得以消除。现介绍两例病例以展示该治疗方案及所能取得的治疗效果。特发性髁突吸收是一种进行性疾病，采用适当的治疗方案可将其消除。
