Upper respiratory tract in cystic fibrosis. Ear-nose-throat survey of 50 children.

An ear-nose-throat survey was carried out on 50 children aged 4 to 
10 years with cystic fibrosis. 10% were shown to be transiently 
deaf, associated with eustachian tube dysfunction. There were no confirmed cases 
of secretory otitis media. 10 children (20%) were found to have 
nasal polyps or gave a history of polypectomy. Though a high 
incidence of middle ear problems in children with cystic fibrosis has 
been reported in the U.S.A., neither deafness nor secretory otitis media 
was found to be a problem in the group studied.
