渐进性髁突吸收致下颌后缩正颌外科的治疗进展
Progression of mandibular retrognathism caused by progressive condylar resorption in orthognathic surgery

摘要： 病因及发病机制仍不明确的渐进性/特异性髁突吸收（PCR/ICR）,是一种发生在髁突的罕见的骨吸收性疾病,临床表现为髁突形态改变、体积减小和下颌升支高度降低等,后期往往出现比较严重的下颌后缩畸形及咬合功能障碍。手术作为一种治疗牙颌面畸形的有效方案,可以达到功能性及面型美观的改善。本文就PCR致下颌后缩的正颌外科治疗作一综述。
Abstract: The etiology and pathogenesis of progressive condylar resorption/idiopathic condylar resorption(PCR/ICR) remain unclear to date. The clinical manifestations of this condition are morphological changes, reduced condylar volume, and decreased ramus height. Serious PCR/ICR can lead to mandibular retrognathism. Surgery as an effective therapy for maxillofacial deformities can improve functionality and maxillofacial aesthetics. This review focuses on the orthognathic surgery of PCR at present.
