摘　　要：目的:探讨恒牙早期男性青少年上气道矢状向空间大小与颅颌面骨结构的相关性,从而找出影响气道大小的骨性特征。方法:收集74例恒牙早期无鼾男性错畸形患者(年龄11～16岁,平均年龄13岁)治疗前头颅侧位片,对颅颌面骨结构及上气道矢状向空间大小进行Delaire头影测量分析。应用SPSS13.0软件包对数据进行处理,采用多元回归分析法研究上气道矢状面大小与颅颌面骨结构异常程度之间的关系。结果:鼻咽气道矢状径(PNS-ad)与面上份高度(UFH)、下颌支后缘的倾斜度(RA)以及颅高与颅底长的比值(Ht/Dp)呈负相关,与前颅底角(CFA)呈正相关;软腭后气道最小矢状径(Ve-PVe)与面上份高度(UFH)、颅高与颅底长的比值(Ht/Dp)呈负相关;舌根后气道最小矢状径(Ph1-Ph2)与颈椎和颅底夹角(CVTA)呈正相关,与下颌平面角(MPA)、下颌体长度(MnBL)、颅高与颅底长的比值(Ht/Dp)呈负相关。结论:恒牙早期无鼾男性错患者上气道矢状向空间大小与颅颌面骨以及头颈姿势关系密切,颅面生长型和气道周围邻近骨结构对气道影响较大。PURPOSE： To investigate the relationship between sagittal upper airway size and craniofacial characteristics in men with malocclusion in early permanent dentition,and to find out the factor that affect the pharyngeal airway size remarkably. METHODS： Seventy-four eephalometric films of nonsnoring males with malocclusion aged from 11 to 16 years（mean 13 years） before treatment were collected and measured with Delaire cephalometric analysis,the results were assessed by SPSS13.0 software package,multiple regression analysis was used to examine the relationship between upper airway size and craniofacial characteristics variation. RESULTS： The size of nasopharyngeal space （PNS-ad） correlated negatively with the upper face height,the inclination of ramus plane,percentage of cranial height to cranial base length. The size of palatopharyngeal space（Ve-PVe） correlated negatively with the upper face height,percentage of cranial height to cranial base length.The size of hypopharyngeal space （Ph1-Ph2） correlated positively with the angle between cervical vertebrae tangent and cranial base, negatively mandibular plane angle, the length of mandibular body and percentage of cranial height to cranial base length. CONCLUSIONS： The sagittal upper airway size of nonsnoring males with occlusion is significantly correlated to the craniofacial skeletal structures and head posture,the types of craniofacial growth and the skeletal structure around have remarkable effect on the upper airway space.
