摘要/Abstract

摘要： 目的研究正颌手术尤其是下颌升支后退手术对骨性Ⅲ类错牙合患者呼吸功能的改变情况。方法选择2013年6月至9月施行正颌手术的骨性Ⅲ类错牙合畸形患者15例，分别在手术前及手术后1周进行多导睡眠监测（PSG），监测数据：平均血氧饱和度值、最低血氧饱和度值、呼吸暂停低通气指数（AHI），将结果进行方差分析和t检验分析。结果术前术后患者的AHI指数均发生变化，术后的平均AHI指数（4.0±0.7）高于术前（0.82±0.69），差异有明显统计学意义(P<0.05)，均以阻塞性呼吸暂停或者低通气为主；所有患者的平均血氧饱和度术后比术前略低，但未见明显统计学差异(P>0.05)。结论在下颌后退有限的距离中，患者的平均血氧并未发生明显的改变，说明将下颌后退控制在一定范围内，能达到既能改善面型，纠正畸形，又能有效防止术后呼吸道阻塞的问题。

Abstract: Objective 　To determine the effects of orthognathic surgery， especially mandibular retrognathia on pharyngeal airway space,respiratory function during sleep. Methods 　15 patients were analyzed using a 1 night sleep study for full polysomnography（PSG） before and 1 week after operation.The monitoring indicators of PSG include AHI index,the average and lowest blood oxygen. Results The data showed that AHI changed significantly after surgery,especially the increase of the obstructive apnea and hypopnea; there was no significant change in the average blood oxygen. Conclusions 　A large amount of mandibular setback might inhibit biological adaption and cause sleep-disordered breathing.We should control the setback in a suitable distance to prevent the obstructive sleep apnea and hypopnea syndrome(OSAHS).

Key words: orthognathic surgery, mandibular retrognathia, polysomnography(PSG), OSHAS
