Polyps are an end result of varying disease processes in the nasal cavities. The most commonly discussed polyps are benign semitransparent nasal lesions (see the images below) that arise from the mucosa of the nasal cavity or from one or more of the paranasal sinuses, often at the outflow tract of the sinuses.The overall incidence of nasal polyps in children is 0.1%; the incidence in children with CF is 6-48%. Among adults, the incidence is 1-4% overall, with a range of 0.2-28%.
A combined medical and surgical treatment is recommended for symptoms control in preventing symptomatic NP recurrence. Oral and topical nasal steroid administration is the primary medical therapy for nasal polyposis.Although much work has been done on chronic rhinosinusitis and nasal polyps there are many questions still unanswered. A prospective population study of a group of age- and sex-matched controlled atopic and non-atopic individuals to consider the incidence of all upper respiratory tract symptoms including acute and chronic rhinosinusitis over a 5 year period.
