下颌后退术对咽腔及其周围解剖结构影响的研究进展

摘要

正畸-正颌联合治疗骨性Ⅲ类错畸形能获得良好的外貌、咬合和咀嚼功能，但同时下颌后退术改变了舌骨、舌体的位置以及在一定程度上缩小了咽腔间隙，影响了呼吸功能。本文就其术后的长期变化和影像学检查进行总结和介绍。%Combining orthodontics and surgery to treat skeletal Class Ⅲ malocclusion can improve the occlusion, masticatory function, and esthetics by markedly changing the position of the mandible. However, mandibular setback surgery causes changes in the position of the hyoid bone and the tongue, and the consequent narrowing of the pharyngeal airway space. It’s a topic that worth to study, and the long-term changes and imaging evaluation are introduced as well.
