Nasal polyps are a very common occurrence in people with CF. Studies have estimated that anywhere from 10% to nearly 50% of people with CF have nasal polyps. Nasal polyps are small, sac-like growths consisting of inflamed (swollen) nasal mucosa, which result in masses in the nose. Their exact cause is unknown but what is clear is that allergy and infections often play a key role in the development of nasal polyps. When examined under the microscope, nasal polyps are essentially bags of tissue and fluid.
Most individuals with nasal polyps complain of nasal blockage affecting both sides of the nose but not necessarily to the same extent. Other symptoms include: runny nose; loss of sense of smell; facial pain or congestion and less commonly, nose bleeds.
If the doctor diagnoses nasal polyps, simple medical treatment with nasal steroids is often effective. In some patients a surgery to remove the polyps (polypectomy) will be necessary.
