Nasal polyps are non-cancerous growths along the lining of the nasal passages or sinuses. Large polyps can obstruct nasal passages and lead to breathing challenges, anosmia (loss of smell), recurrent sinus infections, and other complications.
Adults, particularly those with asthma, frequent sinus infections and allergies, are more susceptible to developing nasal polyps. Children living with cystic fibrosis also often develop nasal polyps.
Extensive Polyps in the Nasal Cavities
What Causes It
Nasal polyps can develop when the mucous membrane in the nasal passages and sinuses becomes chronically inflamed (lasting more than 12 weeks).
An evaluation of symptoms, a physical examination, and a nasal inspection will be conducted. Visible polyps may be detected using a lighted instrument.
