[Otorhinolaryngologic involvement in cystic fibrosis].

ENT involvement is very frequent in mucoviscidosis, particularly rhinitis and sinusitis. This prospective study, which spanned from September 1st, 1988 to August 31st, 1989 anc included 27 children with cystic fibrosis of pancreas was carried out with the intent of determining the incidence of the various associated diseases, their bacteriologic profile, and the optimal therapeutic procedure. Less than a child in 5 is symptomless when the nose and sinuses are affected. Polyposis is found to occur in 6/27 cases, and all children have sinus radio-opacities. Ear disease is rare (1/4 of cases) and is manifested by asymptomatic tubal dysfunction with minimal audiometric repercussions. Bacteriologic specimens of sputum and sinus purulent discharge show simultaneous germ positivity (10 times out of 11). Our therapeutic recommendations are based on our own experience as well as literature data, and are, in our opinion, only relevant for children with clinical signs of disease, as opposed to advocating systematic treatment of sinus foci found on X-ray.
