Twenty-one cases of nasal airway obstruction were analyzed using computed tomography (CT) at the Children's Hospital in Boston between 1980 and 1984. Seven of these patients had stenosis of the entire nasal passage, two had stenosis of the anterior nasal cavity, and 12 had atresia of the posterior choanae. The spectrum of these abnormalities and the optimum technique for CT scanning are discussed.
1980年至1984年间，在波士顿儿童医院对21例鼻气道阻塞病例进行了计算机断层扫描（CT）分析。其中7例患者整个鼻道狭窄，2例患者前鼻腔狭窄，12例患者后鼻孔闭锁。本文讨论了这些异常情况的范围以及CT扫描的最佳技术。
