Laryngeal papilloma: results of treatment with the CO2 laser and podophyllum.

Abstract

From 1976 to 1982, 109 patients with recurrent laryngeal papillomas were treated with a total of 548 CO2 laser excisions followed by podophyllum painting. There was high incidence of multiple sites of involvement, especially the tracheobronchial tree (18.3%) and palate (8.3%). Four patients had pulmonary parenchymal involvement. Patients were treated at 2-month intervals until they entered remission. Thereafter, microdirect laryngoscopies were advised at longer intervals. Remission was achieved in 41%; it occurred at all ages although it was most common during adolescence and rarest in the very young and very old. Many patients obtained remission with the CO2 laser after multiple prior cup forceps removals had not achieved remission. Only two tracheotomies (1.8%) were required and no deaths occurred. When compared with mechanical methods of papilloma removal, CO2 laser excision with podophyllum painting represents a clear advance in terms of preservation of laryngeal physiology and avoidance of life-threatening complications.
