Die Bedeutung eosinophiler Granulozyten in Beziehung zu Allergie und Aspirin-Intoleranz bei Patienten mit Sinusitis polyposa

BACKGROUND The development of nasal polyps might be influenced by different factors such as mucosal inflammation. Infiltration with eosinophils is a common finding, although in largely different quantitis. PATIENTS AND METHODS We investigated 58 patients suffering from nasal polyps who were assigned for endonasal sinus surgery based on endoscopic and CT findings.
