摘　　要：目的通过锥形束CT(CBCT)图像分析高角成人口咽气道的形态与颌面骨骼形态间关系。方法在南昌大学附属口腔医院就诊的患者中随机选取60名高角成人患者的CBCT图像,利用Invivo Dental 5.1分析软件对每位患者的口咽气道各部进行线距、体积以及最小截面积测量,将所有气道测量数据分别与颌骨形态相关指标进行Pearson相关分析。结果在男性组中SNB角与软腭尖矢状径、腭咽气道体积、舌咽气道体积、口咽气道总体积、最小截面积呈正相关,GoGn-SN角与软腭尖矢状径、会厌顶矢状径、腭咽气道体积、舌咽气道体积、口咽气道总体积、最小截面积呈负相关,S-Go/N-Me与软腭尖矢状径呈正相关;在女性组中SNA角与后鼻棘横径呈负相关,SNB角与舌咽气道高、后鼻棘横径、软腭尖横径呈负相关,GoGn-SN角与舌咽气道高呈正相关。结论高角成人口咽气道大小形态与颌骨形态间存在一定联系。在男性组中,随着下颌骨位置的前移,口咽气道有增大的趋势,随着下颌骨顺时针旋转,口咽气道有减小甚至阻塞的趋势;而在女性组中,随着上下颌骨位置的改变,口咽气道仅表现为局部形态的变化。Objective To investigate the relationship between the morphology of oropharyngeal airway and craniofacial morphology in high angle patient by cone beam CT images.Methods CBCT images of60high?angle adult patients were randomly selected in the Affiliated Stomatological Hospital of Nanchang University.The line distances,volumes and min cross?sectional areas of each part of oropharyngeal airway were measured by the InvivoDental5.1software.Pearson correlations analysis of all measurements was performed on all the parameters of oropharyngeal airway and maxillofacial structures.Results In male group,SNB showed positive correction with UTL,PPV,GPV,OPV,MinS.Thereas the GoGn?SN angle showed negative correction with UTL,ETL,PPV,GPV,OPV,MinS,S?Go/N?Me was positive correlated with UTL.In female group,SNA showed negative correction with PNSW.The SNB angle showed negative correction with GPH、PNSW、UTW,GoGn?SN showed positive correction with GPH.Conclusions In high angle adults,the morphology of oropharyngeal airway exist some degrees of correlation with the maxillofacial structures.In male group,the dimension of the oropharyngeal airway tend to increase with the forward of mandible,and tend to decrease or obstruct with the clockwise rotation of mandible.In female group,with the changes of position of maxilla and mandible,oropharyngeal airway showed only partial morhological change.
