title: The role of computed tomography in the management of cancer of the larynx.
abstract: Computed tomography (CT) offers a unique method of displaying the anatomy of laryngeal cancer. Asymmetrical contours of the thyroid cartilages have been found as a normal variant. Marked asymmetry may indicate buckling of the cartilage which could contribute to acute airway obstruction following radiation therapy. A low-density, soft-tissue plane medial to the thyroid cartilages may prove valuable in evaluating cartilaginous involvement with tumor. Computed tomography should make a significant contribution to more accurate planning of radiation therapy portals by showing the relationship of lymphatic spread to the primary tumors.
