对808例无呼吸系统疾病临床或影像学证据的患者，在后前位和侧位胸片上测量气管气柱的冠状径和矢状径。430名男性和378名女性受试者的年龄为10-79岁。假设一个标准范围，包括从平均值或99.7%的正常人群的3个SD，冠状和矢状径的正常上限，分别为25和27毫米，在20-79岁的男性，在女性中，他们分别为21和23毫米。两个尺寸的正常下限为男性13 mm，女性10 mm。与这些数字的偏差反映了病理性气管气柱变宽或变窄。气管口径与体重、身高无显著相关性。
Coronal and sagittal diameters of the tracheal air column were measured on posteroanterior and lateral chest radiographs of 808 patients with no clinical or radiographic evidence of respiratory disease. The 430 male and 378 female subjects were 10-79 yr of age. Assuming a normative range that encompasses 3 SD from the mean or 99.7% of the normal population, the upper limits of normal for coronal and sagittal diameters, respectively, in men aged 20-79, are 25 and 27 mm; in women, they are 21 and 23 mm, respectively. The lower limit of normal for both dimensions is 13 mm in men and 10 mm in women. Deviation from these figures reflects pathologic widening or narrowing of the tracheal air column. No statistically significant correlation was found between tracheal caliber and body weight or body height.
