[Potentialities of autofluorescent spectroscopy in diagnosis of laryngeal and pharyngeal tumors].
Laryngeal and pharyngeal mucosa of 50 patients with malignant (n=56%) and benign (n=44%) laryngeal and pharyngeal tumors was examined with autofluorescent spectroscopy using nitrogen laser LGI-505 (337,1 nm). It was found that autofluorescent spectrum of malignant tumors is significantly less intensive than relevant spectrum of healthy mucosa and benign tumors.
