Polyposis of the nasal airways and/or sinuses

Polyps are benign growths which can occur in the nasal passages or sinuses. Polyps occur in the mucous membrane of the nasal passages and sinuses. The accumulation of numerous polyps is termed polyposis.Imaging is not the best way to assess the nasal mucosal tissue for polyps, the best way is direct visualization of the nasal passages, particularly if you have a family history of polyposis.
