    Abstract:
    Juvenile laryngeal papillomatosis is a rare and benign tumoral disease of childhood characterized by numerous relapses despite complete resection. The ENT treatment of choice is to vaporize the papillomas with a CO2 laser. Since the discovery of a viral etiology (Human Papilloma Virus), resection has been followed by medical attempts to control the disease by using various antiviral treatments. Among the latter, alfa interferon has proved effective during the first six months of treatment. In this article, we report on five cases of refractory juvenile laryngeal papillomatosis treated by excision (CO2 laser in four children, surgical resections in one child) and alpha-r IFN 1.5 x 10(5) U/kg daily. With this strategy, three of the five children are currently disease-free for periods ranging from 22 to 68 months. This series includes one remarkable observation of one child who responded only to double doses of alpha-r IFN, after initial failure at conventional doses. This therapeutic scheme reduced the frequency of relapses in a fourth child. In only one child the treatment did fail to modify the natural course of the disease. Side effects were tolerable and included anorexia (one case), palmar erythema (one case), a flu-like syndrome (two cases) and mild transient transaminase rise (three cases) not precluding further treatment. CO2-laser caused one laryngeal oedema and synechia of the anterior commisure of the vocal laryngeal cords in one other case.
