Table of Contents

Definition

Nasal polyps are sac-like growths of inflamed tissue lining the nose (nasal mucosa) or sinuses.

See also: Sinusitis


Causes, incidence, and risk factors

Nasal polyps typically start near the ethmoid sinuses (located at the top of the inside of the nose) and grow into the open areas. Large polyps can block the sinuses or nasal airway.

People with the following conditions are more likely to also have nasal polyps:

  • Aspirin sensitivity (wheezing)
  • Asthma
  • Chronic sinus infections
  • Cystic fibrosis
  • Hay fever (allergic rhinitis)
