Computed tomography of the larynx: a clinical and pathologic study.
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.
