Nasal and sinus infection is usually associated but the precise role of infection in their causation is unknown. There are various diseases associated with polyp formation :- chronic rhinosinusitis, asthma, cystic fibrosis, kaagener's syndrome, young's syndrome, churg - strauss syndrome, nasal mastocytosis, aspirin intolerance.
