Pathological and clinical assessment of polypoid hypertrophy of the vocal cords

Polypoid hypertrophy of mucosa of the vocal cord is the most common non-neoplastic disease of the larynx. This hypertrophy has a form of simple polyp of vocal cord or polypoid hypertrophy of the whole length of one or both vocal cords. In most cases a course of the disease is typical. In a few cases we can observe changes in polyp epithelium, i.e. hyperplasia or even dysplasia. Clinical and histological analysis of 809 patients treated because of laryngeal polyps (by Kleinsasser microsurgical procedure) within the period of 1981-1995 at ENT Clinic in Gdańsk was made. Sex and age of the patients, macroscopic picture of the disease as well as treatment and results were assessed. Special attention was paid to the problem of polyp epithelium rebuilding. In a few cases, polyp of the vocal cord should be assessed as praecancerous state.
