title: Treatment and prognosis of nasal polyps in cystic fibrosis.
abstract: Nasal polyposis complicated the course of fibrosis in 157 (26%) of 605 patients. Onset before age 5 years or after age 20 years was rare. Polyposis was the initial symptom of cystic fibrosis in 13 patients. Common symptoms included obstruction to nasal air flow, mouth breathing, epistaxis, and rhinorrhea. Intranasal and oral corticosteroids and antihistamines were ineffective in preventing recurrences but did occasionally afford symptomatic relief of obstruction. Nineteen (31%) of 62 patients who never had surgery had spontaneous and permanent disappearance of polyps. Simple polypectomy was an adequate procedure for patients with substantial nasal symptoms. There were no visual complications. Other surgical complications were rare. Children and adolescents with nasal polyps should have sweat tests by pilocarpine iontophoresis to rule out cystic fibrosis.
