The management of epistaxis in patients with hereditary haemorrhagic telangiectasia (Osler-Weber-Rendu) is often a perplexing problem. In the past, cautery, cryosurgery, and septodermoplasty have all been used with varying degrees of success. The Candela flashlamp-pulsed dye laser was developed for management of vascular lesions (port-wine stains and telangiectasia). The results of our prospective trial utilizing this laser in the treatment of intranasal telangiectasia in patients with hereditary haemorrhagic telangiectasia are presented.
