摘　　要：目的通过CBCT观察研究中度OSAHS成人的上气道容积及与下颌骨大小位置的相关性,为临床诊疗提供指导。方法 26例中度OSAHS患者和19例无鼾对照组拍摄CBCT,将其数据保存为DICOM格式,采用MIMICS17.0软件重建下颌骨及上气道并测量分析,测量指标为上气道腭咽,舌咽容积和上气道口咽段总容积,下颌骨长度,下颌角宽度,颏点到椎前距离,比较两组人群的差异,并通过Pearson相关分析下颌骨各指标与上气道容积的相关性。结果 OSAHS组人群的上气道腭咽,舌咽及口咽容积均较对照组明显减小,两者差异显著,P<0.001具有统计学意义。而OSAHS组和无鼾对照组的下颌骨的长度,下颌角宽度无显著性差异。下颌骨的长度和宽度与上气道容积均无明显相关,而下颌骨颏点至椎骨距离与上气道容积相关性较好。结论 OSAHS患者的上气道口咽段容积较正常人明显减小。下颌骨位置是影响上气道口咽容积大小的关键因素。Objective The volume of upper airway in adult OSAHS patients and its correlation with mandible position were studied by CBCT observation,which provided guidance for clinical diagnosis and treatment.Methods 26 patients with moderate OSAHS and 19 normal people were photographed CBCT,and the data were saved as DICOM format,the mandible and upper airway were reconstructed by MIMICS17.0 software, and the measurements were the minimum sagittal diameter of upper airway,the smallest coronal diameter of upper airway palate,The total volume of pharyngeal volume,the length of mandible,the width of mandible angle,the distance between the chin and anterior vertebrae were compared between the two groups,and the correlation between the mandible measurement and the upper airway volume was correlated by Pearson.Results The upper airway palate, pharyngeal and oropharyngeal volume of the OSAHS group were signifcantly reduced compared with the control group, the difference was signifcant and the P〈0.001 was statistically signifcant. The mandible length, mandible angle width of OSAHS Group and non-snoring control group were not signifcantly different. The length and width of the mandible were not correlated with the upper airway volume,and the mandible-to-vertebral distance was better than that of upper airway volume.Conclusion The upper airway oropharyngeal volume of OSAHS patients decreased signifcantly compared with normal people.Mandible position is the key factor affecting the oropharyngeal volume of upper airway.
