Nasal polyps are soft, painless, noncancerous growths that develop on the lining of the nose or sinuses. They are often shaped like teardrops and can form in groups. Nasal polyps are caused by long-term swelling and inflammation in the nose from allergies, asthma, or infection. They can partially block the nasal passages and sinuses, causing breathing problems, loss of smell, and infections. Nasal polyps can affect anyone, but they are more common in young and middle-aged adults.

Symptoms of nasal polyps include:

• Runny nose
• Stuffy nose
• Postnasal drip
• Decreased sense of smell
• Loss of taste
• Facial pain or pressure
• Snoring
• Frequent infections

Nasal polyps can be diagnosed by a doctor who will use a nasal endoscope to see inside the nose. CT or MRI scans of the sinuses can also show findings that suggest the presence of nasal polyps. Medication and outpatient surgery can shrink nasal polyps and relieve symptoms. The first course of treatment for nasal polyps is often a nasal corticosteroid spray prescribed by a doctor. Oral corticosteroids may also be used. If the nasal polyp isn’t removed or shrunk by medication, then endoscopic surgery may be required to remove the polyps.
