Nasal polyps are tear-shaped growths that occur inside the nose. They are non-cancerous and often associated with asthma or allergies. Some people have nasal polyps with no symptoms, especially if the polyps are small. Larger polyps block sinus drainage, which can lead to infection. Nasal polyps can be treated with medication, but they tend to recur and might need to be removed surgically.
Symptoms of nasal polyps vary based on the size, but include nasal congestion, sneezing, runny nose, postnasal drip, loss or reduction of sense of smell, loss of taste, facial pain, itchy eyes, and chronic sinus infections.
Nasal polyps are diagnosed with a simple endoscope exam and first treated with a nasal corticosteroid spray. Larger polyps often require surgical removal, but might not be effective for patients with polyps who also suffer from asthma and/or aspirin sensitivity. A combination of long-term treatment can be effective for managing symptoms and restoring sense of smell and taste in these cases.
