Nasal aspects of cystic fibrosis in children.

Despite the extraordinary prevalence of upper respiratory allergy and infection in children 
nasal polyposis is an extremely rare condition. Seven cases of cystic 
fibrosis are presented in order to demonstrate the nasal aspects of 
the disease. All but one had nasal polyposis. The literature has 
been reviewed with particular reference to clinical, radiological and histo-pathological features. 
Conservative treatment is stressed.
