Vocal cord polyps: Incidence, histology and pathogenesis

On the basis of clinical and histologic examination, history and epidemiologic survey of 591 patients with vocal cord polyps, the authors evaluate the morphology of the pathologic substrate, indicate possible pathogenesis and analyse the most frequent factors in the formation of polyps such as vocal abuse and unfavourable microclimate at work. Sex does not play any role in the incidence, and the histologic structure is not related to the time factor.
