Abstract
Roentgenologic examination of the larynx is of invaluable help in the assessment and classification of laryngeal tumors. Soft tissue roentgenograms, tomograms and laryngograms are complementary to each other and add to the clinical examination. We have compared whole organ serially-sectioned laryngeal carcinoma specimens with preoperative tomograms and laryngograms in a large number of clinical cases and have chosen illustrative material from 10 such cases. Tomograms and laryngograms provide accurate assessment and evaluation of the surface extension of such tumors. The assessment of deep invasion with cartilaginous destruction and spread outside the laryngeal framework, however, is extremely difficult, both clinically and by the currently used roentgenologic techniques. Small tumor lesions, and extensive postoperative edema are difficult to evaluate roentgenologically. A plea is made for closer liaison between the diagnostic radiologist, the laryngologist and the surgical pathologist. The need for better methods of assessing deep extension of tumor growth is stressed.
