Laryngeal Papillomatosis is a disease that most often affect the true vocal folds, epiglottis, false vocal folds and may extend in the entire larynx. There isn't a consensus about a classification of the site and intensive of the lesions. AIM: To propose a staging based on the classification of the site and intensity of the lesions in the larynx that can have easily application for the physician. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: We divided the larynx in three sites: supraglottis (S), glottis (G) and infraglottis (I); and in four degree of extension. Classification: S1 (focal lesion), S2 (less than 2/3 of extension of the lumen), S3 (more than 2/3 of extension) and S4 (obstructive lesion or tracheotomy); G1 (focal lesion on the fold or on the anterior or posterior commissure - less than 1/3 of extension), G1a (only one vocal fold) G1b (both vocal folds), G2 (more than 1/3 extension of the vocal fold), G2a (only one vocal fold), G2b (both vocal folds), G3 (more than 2/3 extension of the vocal fold) and G4 (obstructive lesion or tracheotomy); I1 (focal lesion), I2 (less than 2/3 extension of the lumen), I3 (more than 2/3 extension of the lumen), and I4 (obstructive lesion or tracheotomy). Based on this topographic classification we obtain 4 stages: I, II, III e IV. We evaluated 74 laryngoscopes of 10 patients with laryngeal papillomatosis before and after the treatment with cidofovir to establish the viability of the staging. RESULTS: All the exams could be submitted to the classification and staging. CONCLUSION: We concluded that the staging proposed was viable on the studied population.
