Recent interest in the application of computed tomography (CT) to the evaluation of laryngeal tumors, and the fact that the larynx offers the unique opportunity of whole organ study after total laryngectomy, led to a prospective study of laryngoscopy, conventional tomography, and CT in relation to pathologic findings. The results showed that CT gives an exact assessment of laryngeal anatomy and tumor involvement, particularly in the paracordal and pre-epiglottic spaces. The laryngeal cartilages, which are not well demonstrated by any other means, are accurately delineated by CT. There is also good demonstration of the laryngeal surface of the epiglottis, including the anterior commissure, which is poorly shown by other radiologic methods and is sometimes poorly seen on laryngoscopy. Because CT and conventional tomography present images at 2 different planes, at right angles to each other, we believe that CT is entirely complementary to conventional tomography.
最近，计算机断层扫描（CT）在喉肿瘤评估中的应用受到关注，并且喉在全喉切除术后提供了对整个器官进行研究的独特机会，这促使我们对喉镜检查、传统断层扫描和CT与病理结果的关系进行了一项前瞻性研究。结果表明，CT能够准确评估喉部解剖结构和肿瘤累及情况，尤其是在声门旁间隙和会厌前间隙。其他任何方法都无法很好显示的喉软骨，CT能够准确勾勒出来。会厌的喉面，包括前联合，也能很好地显示，而其他放射学方法对此显示不佳，喉镜检查时有时也难以看清。由于CT和传统断层扫描呈现的图像处于两个相互垂直的不同平面，我们认为CT与传统断层扫描完全互补。
