Nasal polyps are benign growths that occur on the mucosal lining of the nasal passages. They are typically small and though noncancerous can still cause obstructions of the sinuses, leading to congestion, breathing problems and sinus infections.
What Causes Nasal Polyps?
Some people develop nasal polyps randomly, but most often there is some sort of triggering mechanism. Common triggers include asthma, hay fever, chronic sinus infections, cystic fibrosis, and sensitivity to aspirin and other NSAIDs. Genetics may also play a role.
A diagnosis is usually made through visual inspection with an otoscope or nasal endoscopy. An imaging test, either a CT scan or MRI, can be useful in determining the size of the polyp and in ruling out more serious growths, such as tumors. Allergy tests may be administered in order to identify the substance responsible for your symptoms.
