An ear-nose-throat survey was carried out on 30 children with cystic fibrosis (CF) between two and 17 years of age. There were three (10%) confirmed cases of secretory otitis media. One child had previous surgery for polyps. Ten children had chronic pansinusitis mildly responsive to medical therapy. Hypertrophy of the nasal conchae was detected in eight cases. The data showed that the risk of ear-nose-and-throat disease was increased in CF patients, but audiologic problems are not very common in CF patients. CF should be kept in mind in children who have nasal polyps, hypertrophied turbinates or sinusitis unresponsive to medical therapy.
