Nasal polyps in children.

The inflammatory nasal polyp is the most common benign or malignant nasal mass seen in children. Nasal polyps in the pediatric population appear to occur as inflammatory responses to bacterial infections. In 33% of the patients with polyps whom we studied, antral choanal polyps were noted, and in 20% of the patients the polyps were unilateral but not antral choanal. In 18% of the patients the polyps were bilateral and in an additional 29% they occurred bilaterally in association with cystic fibrosis. History of an allergy is infrequently associated with nasal polyps; allergies are potentially major contributing factors to nasal polyps only in patients without cystic fibrosis whose nasal polyps are bilateral. Patients with antral choanal polyps are most successfully managed by simultaneous Caldwell-Luc antrostomy and polypectomy. Sixty percent of patients with nasal polyps and cystic fibrosis are adequately managed with a single intranasal polypectomy. Simultaneous sinus surgery and polypectomy should be considered for all patients with recurrent polyps and for all patients with clinical or radiographic evidence of significant sinusitis. Complications, including epistaxis and intranasal synechia, occurred in 3% of the 170 surgical procedures performed.
