Abstract		Differences in autofluorescence between normal and malignant tissues offer new possibilities for detecting and localizing early laryngeal carcionomas. In the present study imaging was performed using a specially properties of normal and cancerous tissues without photodynamic drugs. Fluorescence was induced by a heliumcadmium laser, captured by an image-intensified camera and displayed on a video monitor after previous computerization. Thirty patients were evaluated, of whom 18 had suspect malignancies. Laryngoscopic appearances during standard microlaryngoscopy were compared to fluorescence images, computerized fluorescence intensities and histopathologicalfindings. The experience from this study shows that autofluoresence laryngoscopy may be a useful complementary method for detecting laryngeal malignancies.
