About Chronic Rhinosinusitis with Nasal Polyps

What are Nasal Polyps?

Nasal polyps are non-cancerous growths that form in the lining of the nasal passages, often as a result of inflammation from chronic rhinosinusitis (CRS), termed CRS with nasal polyps (CRSwNP).1 The condition is often characterized by long-term disease burden and associated with poor quality of life.2 Studies have shown that CRS aects approximately 12.8% of the Malaysian population and 10.7% in Singapore.3,4

The polyps often resemble hanging grapes or are teardrop-shaped.5,6 They are commonly yellow in colour, but can also be white, grey or pink.1,5 Because nasal polyps usually aect both nasal passages, their presence on only one side might require further examination, as this could indicate a malignant growth.7

Who is affected by nasal polyps?

Nasal polyps are estimated to aect 1–4% of the general population.8 They occur in 20% of individuals with CRS.7 Its incidence increases with age, reaching a peak at age 60 years, and is twice as common in men than in women.1,5
