5-Aminolevulinic acid photodynamic diagnosis of laryngeal papillomatosis

Photodynamic diagnosis is a promising method in the treatment of laryngeal papillomatosis, which includes an assessment of the increased visual and spectrometric contrast of papillomatosis masses against the background of the introduction of the photosensitizer. We have developed a method of treatment of laryngeal papillomatosis in two stages: intraoperative diagnosis using the domestic preparation of 5-aminolevulinic acid hydrochloride and subsequent surgical treatment using a carbon dioxide laser. Using the new method, we treated 21 patients, of which 13 (61.9%) had the inter-recurrent period longer than 12 months.
