摘　　要：目的:评价上颌前牵引矫治对骨性Ⅲ类错患者上气道形态的影响,探讨颅颌面结构改变与上气道形态改变的关系。方法:上颌矢状向发育不足的骨性Ⅲ类错患者22例,根据矫治前X线头颅定位侧位片上颈椎发育程度判断,均为生长发育期患者。进行上颌前牵引治疗。采用SAS8.2软件包,对治疗前、后X线头颅侧位片上的数据进行配对t检验,以评价前牵引疗效,以单因素相关分析评价上气道间隙变化与颅颌面形态改变之间的关系。结果:矫治后患者的鼻咽(PNS-ad1,PNS-ad2)及腭咽(PSP-SPPW,P-MPW)气道间隙显著增大(P<0.01),舌咽气道间隙(Tb-TPPW)显著减小(P<0.05),喉咽气道间隙(V-LPW)无显著变化(P>0.05)。PNS-Ba的改变分别与PNS-ad1、PNS-ad2以及V-LPW的改变存在相关性(P<0.05);Hy-H1的改变分别与P-MPW、V-LPW的改变存在相关性(P<0.05);Hy-H0的改变与V-LPW的改变存在相关性(P<0.05),其余颅颌面形态结构的改变与上气道间隙的改变无显著相关性(P>0.05)。结论:上颌前牵引对上气道间隙有一定影响,且颅颌面结构改变与上气道形态改变之间存在一定联系。PURPOSE： To evaluate the effect of maxillary protraction on upper airway dimensions in skeletal Class m malocclusions and to investigate the relationship between changes in craniofacial morphology and upper airway dimensions. METHODS： 22 patients who had maxillary retrognathism confirmed by cervical vertebral maturation and treated with face mask protraction. Pre- and post-treatment cephalometric radiographs were analyzed with SAS8.2 software package for paired t test and correlation analysis. RESULTS： The dimensions of PNS-adl,PNS-ad2,PSP-SPPW, P-MPW increased significantly （P〈0.01）, Tb-TPPW decreased significantly （P〈0.05）. The change of V-LPW was not significant （P〉0.05）.Correlation was found between changes of PNS-Ba and PNS-adl, PNS-ad2,V-LPW （P〈0.05）;ehanges of Hy-H1 and P-MPW,V-LPW （P〈0.05）;changes of Hy-H0 and V-LPW （P〈0.05）. No correlation was found between other pharyngeal measurements and investigated craniofacial variables （P〉0.05）. CONCLUSIONS： Maxillary protraction can affect the upper airway structures. In addition, variables on craniofacial morphology are relative with upper airway dimensions.
