THE AVERAGE otolaryngologist is frequently and justifiably at a loss to choose the appropriate radiographic examination for his laryngeal patient. The laryngologist (as well as the radiologist) wants an examination that will provide maximum information, patient safety, and utility of administration. Because there are several types of study available, a careful reassessment of the technique appears to be justified. Methods of radiographic evaluation of laryngeal carcinoma include plain x-ray films of the neck in all projections, tomography, cinefluorography, positive contrast laryngography, and high kilovolt (peak) (kvp) laryngography. Each of these methods has certain advantages and disadvantages. Plain x-ray films have the distinct advantage of being easy to obtain, relatively inexpensive, but uniformly they yield little information. Tomography yields a fair amount of information regarding the laryngeal structures, but exposes the patient to a large amount of radiation. This is particularly true if one has the patient perform the various maneuvers
