We report about a case of a 13-year-old boy with recurrent respiratory papillomatosis. The patient suffered from recurrent stridor and permanent hoarseness. On examination large islands of papillomas were found on both sides of the glottis region. The larynx was then examined with Narrow Band Imaging, a new technique, which enables the medical professional to investigate the capillary and submucous vasculature of the mucosa. Endolaryngeal findings showed multiple vascular loops in the capillary layer, larger submucous vessels could not be found. These findings may be interesting for surgeons, who perform laser ablation of papillomas. Bleedings from large-bore submucous vessels are unlikely, as long as the surgeon ablates superficially, within the plane of the papillomas.
