Nasal polyps are common in people with cystic fibrosis, affecting between 10-50% of people with CF. Polyps are small, sac-like growths of inflamed nasal mucosa (masses in the nose) that are caused by chronic inflammation in the nasal lining. Examined under a microscope, nasal polyps are essentially bags of tissue and fluid.
The exact cause of nasal polyps is unknown but allergy, infections and chronic congestion often play a key role.
Most people with nasal polyps complain of nasal blockage which affects both sides of the nose (not to the same extent). Other symptoms include runny nose, loss of sense of smell, facial pain or congestion and nose bleeds (less common).
Diagnosing nasal polyps is generally straightforward – examining the patient, often with nasal endoscopes.
Polyps are often effectively treated with steroids or a simple surgical procedure – a polypectomy. A polypectomy removes the polyps to relieve nasal obstruction. A polypectomy can take place in a specialist’s office if there are just a few, isolated polyps.
There are rare surgical risks including bleeding and impact to the eyes and brain. Major benefits are an enhanced sense of smell, decreased nasal/facial pain and congestion.
Surgery does not cure the original cause of polyps. Most specialists recommend treating the underlying congestion to decrease the chance polyps will recur. Some preventative suggestions include:
