目的:利用低剂量多层螺旋CT儿童序列及多平面重组(MPR)技术探索儿童鼻咽部气道大小及形态。资料及方法:回顾性性分析2005.05~2008.08来我院检查鼻及鼻咽部儿童的CT扫描图像,选择符合条件的3~14岁患儿73例,根据儿童鼻咽部腺样体生理特点分两组,一组3~7岁,二组8~14岁,分析儿童鼻咽部A值、N值及A/N值,总结鼻咽腔形态学特点。结果:3~14岁(两组)儿童正常鼻咽部气道失状位均呈镰刀形,周围脂肪间隙清晰,后缘光整连续;一组及二组A值均数分别为9.23±4.85 mm、9.56±4.74 mm;N值均数分别为19.23±3.5 mm、21.5±4.9 mm;两组A值及N值均数间没有统计学差异;A/N值范围一组为0.2~0.58,二组0.21~0.6。结论:3~14岁健康儿童鼻咽腔失状位呈弓向上的镰刀形,边缘光整,周围脂肪间隙清晰,A/N≤0.6。
