Nasal polyps

What is Nasal polyps?

Nasal polyps (Figure 1a-d) are fleshy outgrowths from the lining of the nose or sinuses. Most of the time, they develop as a result of chronic sinusitis and are due to chronic inflammation. Occasionally, nasal polyps can be due to a tumour, which is most often benign (non-cancerous) and rarely malignant (cancerous). The management of nasal polyps can be complex and depends on the nature of the polyp (benign vs malignant).


It is best that you discuss with your ENT Specialist on the best management plan that is suitable for your condition. Additional tests such as biopsy (removal of a small piece of tissue for analysis) and imaging (CT scan or MRI scan) may be required to investigate nasal polyps (Figure 2).
