A nasoendoscopic examination may be done to confirm the presence of polyps as well as to evaluate the extent of disease. Your doctor may also suggest allergy skin tests to find out if there are any allergies that may be contributing to the chronic inflammation.
A Computed Tomographic (CT) scan of the sinuses may be done to determine the extent of the polyps in some cases, as well as to identify any other possible obstructions within the nasal cavity. The scan is also useful if surgery is needed.
