Malignant tumors of the larynx.

A rational choice of treatment for patients with malignant tumors of the larynx depends upon a thorough evaluation of the location, size, and extent of the lesion. Roentgenological examinations of the larynx are a valuable adjunct to clinical and laryngoscopic examinations. In interpretation of roentgenographic findings of malignant tumors of the larynx, a good knowledge of the anatomy of the head and neck, and of the nature, history, and routes of spread of the lesions of the larynx is essential. A correct interpretation needs careful scrutiny of all the roentgenograms; only a persistent abnormality should be regarded as significant. Many of the changes are subtle and require judicious elucidation. Others are quite straightforward and easily recognized. Constant attention to details and willingness to use wisely the different techniques are necessary if the maximum contribution to the diagnosis and management of malignant tumors of the laynx is to be achieved.
