正颌外科治疗阻塞性睡眠呼吸暂停综合征

为了总结使用正颌外科方法治疗严重的小颌或下颌后缩畸形伴阻塞性睡眠呼吸暂停综合征（ｏｂｓｔｒｕｃｔｉｖｅｓｌｅｅｐａｐｎｅａｓｙｎｄｒｏｍｅ，ＯＳＡＳ）后，患者面型、关系以及口颌系统功能获得的改善，作者通过１０例患者的手术治疗对颌骨和舌骨的移动，同时改善面型、口颌系统功能并扩张舌根水平的上气道，从而治疗ＯＳＡＳ。讨论了治疗ＯＳＡＳ的正颌外科手术方法，并提出了正颌外科治疗ＯＳＡＳ的适应证和外科治愈指标。

A clinical study on treating the obstructive sleep apnea syndrome with orthognathic surgery

When severe mandibular hypoplasia accompanying obstructive sleep apnea syndrome (OSAS) were treated by the orthognathic surgery, the results were quite successful not only in patients' profile, occlusion and functions, but also in the subjective and objective evaluations related to OSAS. The paper summarizes the methods and surgical procedures of treating OSAS with orthognathic surgery through the diagnoses and treatment of a group cases suffering from severe mandibular hypoplasia accompanying OSAS. Severe mandibular hypoplasia can cause not only the deformity and the disorder of occlusion, but also the OSAS. The advancements of mandible and hyoid with orthognathic surgery can improve the patients'prfile, occlusion and expand the patency of upper airway, so it can cure OSAS.
