摘　　要：目的探讨不同矢状骨面型均角患者颅颈姿势变量与上气道形态学指标之间的相关性。方法90例均角患者按矢状骨面型均分为骨性Ⅰ类、Ⅱ类及Ⅲ类组,3组均角患者于正畸治疗前拍摄头颅侧位片及锥形束计算机断层扫描(CBCT),将头颅侧位片导入几何画板软件测量各组颅颈姿势相关变量[颅垂直角(NSL/VER)、颅颈角(NSL/OPT、NSL/CVT)、颈水平角(CVT/HOR、OPT/HOR)及颈凸角(OPT/CVT)],CBCT数据以DICOM格式导入Invivo6.0.5测量上气道形态学指标[上气道高度(H、H1、H2、H3)、容积(V、V1、V2、V3)、横径(PNS L1、SP L1、TE L1)、矢状径(PNS L2、SP L2及TE L2)及气道横径/矢状径(ratio1、tatio2及ratio3)],采用Pearson相关性分析评估所有均角患者颅颈姿势变量与上气道形态学指标之间的相关性。结果骨性Ⅱ类组均角患者NSL/VER、NSL/OPT、NSL/CVT大于骨性Ⅰ类、Ⅲ类组(P<0.05),CVT/HOR、OPT/HOR、口咽处气道矢状径(SP L2、TE L2)及上气道容积小于骨性Ⅰ类、Ⅲ类组(P<0.05);所有均角患者颅颈角(NSL/OPT、NSL/CVT)与上气道容积(V、V1、V2、V3)及口咽处气道矢状径(SP L2、TE L2)呈负相关(P<0.01),颈水平角(CVT/HOR、OPT/CVT)与上气道容积(V、V1、V2、V3)及口咽处气道矢状径呈正相关(P<0.05)。结论不同矢状骨面型均角患者颅颈姿势与上气道形态存在一定相关性,表现为骨性Ⅱ类均角患者的颅颈姿势最伸展、上气道容积最小。Objective To investigate the correlation between craniocervical postural variables and upper airway morphological indexes of patients with different sagittal skeletal patterns.Methods Lateral cephalometric radiographs and cone beam computed tomography(CBCT)of 90 untreated normodivergent adults were included and divided into three groups according to sagittal skeletal patterns:classⅠ,classⅡ,and classⅢ,with 30 cases in each group.The lateral cephalometric radiographs were analyzed using geometric software to measure posture-related variables:NSL/VER,NSL/OPT,NSL/CVT,CVT/HOR,OPT/HOR,and OPT/CVT.The CBCT data were imported in DICOM format into In vivo 6.0.5 to measure upper airway morphological indices:H,H1,H2,H3,V,V1,V2,V3,PNS L1,SP L1,TE L1,PNS L2,SP L2,TE L2,ratio1,ratio2,and the ratio3).Pearson correlation analysis was used to evaluate the relationship between craniocervical posture variables and upper airway morphological indices across the different skeletal pattern groups.Results The NSL/VER,NSL/OPT and NSL/CVT angles of patients with classⅡwere significantly larger than those of patients with classⅠand classⅢ(P<0.05),while CVT/HOR,OPT/HOR,sagittal diameter at the oropharynx(SP L2,TE L2),and upper airway volume were significantly smaller compared with class I and class III(P<0.05).The craniocervical angles(NSL/OPT,NSL/CVT)showed a negative correlation with upper airway volumes(V,V1,V2,V3)and sagittal diameters at the oropharynx(SP L2,TE L2;P<0.01),whereas cervical horizontal angles(CVT/HOR,OPT/CVT)were positively correlated with upper airway volumes and sagittal diameters(P<0.05).Conclusion There is a certain correlation between craniocervical posture and upper airway morphology in patients with different sagittal skeletal patterns,as shown in patients with skeletal classⅡwho have the most extended craniocervical posture and the smallest upper airway volume.
