[Narrow-band imaging endoscopy for diagnosis of adult laryngeal papillomatosis - case raports].

The laryngeal papillomas belong to the group of non-malignant tumours. The risk of getting sick increases with the number of contingent sexual contacts, smoking, alcohol abuse and untreated gastro-oesophageal reflux. This paper describes five cases presenting different levels of exposure to the risk factors and variable course of adult laryngeal papillomatosis. These people, in addition to routine diagnostics, were examined using endoscopy with the use of narrow beam of light, which turns out to be a useful diagnostic tool in the case of laryngeal papillomatosis.
