The Laminagraphy of the Larynx: As an Aid in the Diagnosis of Laryngeal Cancer

Laminagraphic observations have been made on 25 cases with laryngeal cancer, which were classified in supraglottic (8), glottic (5), subglottic (6) and extrinsic (6) type from the laryngoscopic (25 cases) and macroscopic findings (15 resected cases). From these observations it was concluded that the laminagraphy of the laryngeal cancer was of value in determining the exact limits of subglottic extension and the invasion to piriform sinus, in the visualization of the regression or the extension of tumor during irradiation therapies, and in the confirmation of the direct and indirect laryngoscopy.
