We studied the feasibility of computed tomographic evaluation of the neonatal airway. Three neonatal larynges, removed at necroscopy, were examined by computed tomography. Good resolution of soft tissue, cartilage and airway lumen was obtained in these small specimens. On the basis of these findings two neonates with acquired subglottic stenosis were examined by endoscopy, soft tissue airway radiographs, and computed tomography. Measurements of radiation dose revealed that a computed tomographic study delivered 36% of the mean tissue dose of standard image intensifier fluoroscopy. Computed tomography and fluoroscopy both demonstrated the degree and length of this stenosis accurately. An advantage of CT over conventional imaging procedures was better definition of the cross sectional area of the airway.
我们研究了计算机断层扫描评估新生儿气道的可行性。对3个在尸检时摘除的新生儿喉进行了计算机断层扫描检查。在这些小标本中获得了软组织、软骨和气道腔的良好分辨率。基于这些发现，对2例获得性声门下狭窄的新生儿进行了内镜检查、气道软组织X线片和计算机断层扫描。辐射剂量测量显示，计算机断层扫描研究的平均组织剂量为标准影像增强荧光透视的36%。计算机断层扫描和荧光透视均能准确显示这种狭窄的程度和长度。与传统成像方法相比，计算机断层扫描的一个优势是能更好地界定气道的横截面积。
