摘　　要：目的定量确定南方某地区正常成年人上气道各平面径线及横截面积的CT测量值范围,为本地区阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)的诊断及治疗提供参考指标。方法对180例健康成年人(男92例,女88例,平均48.6岁)进行上气道螺旋CT扫描,应用图像软件分别测量软腭后区、悬雍垂区、舌后区及会厌后区四个平面的矢状径、横径及横截面积,软腭的长度及厚度,经统计学处理确定其正常值范围。结果得到南方某地区正常成年人上气道四个平面的CT测量值,软腭后区各径线及横截面积最小,至会厌后区逐渐增大,绝大多数人横径大于矢状径,横断面上气道呈横椭圆形、半月形及其他不规则形。结论螺旋CT能够准确的、可重复性的测量上气道的径线及横截面积,观察上气道的解剖形态,建立南方地区正常成年人上气道CT测量值范围,对于本地区OSAHS的诊断及治疗有重要的临床意义。To evaluate the crosssection area with its corresponding sagittal and transverse diameters of upper airway with normal adult by means of spiral CT scan and to analyze the value of the results in the clinical diagnosis and management of patients with obstructive sleep apnea hypopnea syndrome （OSAHS）. METHODS One hundred and eighty healthy adults were involved in this study. Their upper airways were measured and reconstructed by the software of spiral CT after pharynx scanning. The cross-section area with its corresponding sagittal and transverse diameters at naso-, velo-, and tonguepharyngeal level, and the length and thickness of soft palate were measured respectively. RESULTS The cross-section area with its corresponding sagittal and transverse diameters of various levels of pharyngeal in normal adults were obtained. CONCLUSION The cross-section area with its corresponding sagittal and transverse diameters of upper airway can measured with spiral CT accurately and repeatedly. The results can be used for the diagnosis and management of patients with OSAHS.
