Management of nasal polyposis.

These guidelines are modified from the recent EAACI Position Paper. Nasal polyposis is characterized by an inflammatory process, the factors of which are summarized. Recently, Staphylococcus aureus enterotoxins have been identified to modify the disease. A classification system for polyps, grading systems and epidemiologic data are given, frequent comorbidities are discussed. The diagnostic management is based on endoscopy and CT scanning. A score of severity is proposed. The therapeutic management consists of the medical treatment options, which are given with evidence-based recommendations. Surgical treatment is indicated after failure of medical treatment and commonly performed by endoscopy. Nevertheless medical therapy must be continued after surgery to prevent recurrences. Algorithms of decision are finally proposed [corrected]
