计算机断层扫描测量了130名受试者在头20年里的气管长度、前后直径、横径、横截面积和包含体积。6岁以下患者在低肺容量下进行扫描。其他人则在肺活量或接近肺活量时进行扫描。结果按年龄和性别显示。男孩和女孩之间没有差异，直到14岁，女孩的气管停止生长。数据表明，男性的气管在身高增长停止后的一段时间内会继续增大（但不会变长）。到6岁时，平均横径大于平均横径；在18岁之前，直径几乎相同，这时AP直径通常会变大一些。气管横切面接近圆形，尤其是在高肺容量时。在单个气管中，水平间的变化很小。这些测量在检测气管异常、呼吸生理问题、气管插管、内窥镜检查和气管切开术中应该是有用的。
Computed tomography measured the lengths, anteroposterior (AP) diameters, transverse diameters, cross-sectional areas, and contained volumes of the tracheas of 130 subjects in their first two decades. Patients below age 6 were scanned at low lung volumes. The others were scanned at or near total lung capacity. The results are shown by age and gender. There were no differences between boys and girls until age 14, when girls'' tracheas stopped growing. The data suggest that male tracheas continue to enlarge (but not lengthen) for a time after growth in height ceases. Mean transverse diameters tended to be greater than mean AP diameters to the age of 6; the diameters were then nearly identical until age 18, when the AP diameters usually became slightly larger. The tracheas were nearly round in cross section, especially at high lung volumes. In individual tracheas, changes from level to level were small. These measurements should be useful in the detection of tracheal abnormalities, in problems in respiratory physiology, and in endotracheal intubation, endoscopy, and tracheostomy.
