Nasal endoscopy is a quick, outpatient procedure in which your health care provider threads a narrow tube equipped with a camera into your nose to diagnose a variety of sinus conditions ranging from a deviated septum to sinusitis, polyps and tumors. Patients who suffer from chronic sinus infections, nose bleeds, loss of smell, facial pain or difficulty breathing from their nose may be candidates for nasal endoscopy. While the test may cause some slight discomfort as the tube is inserted, a local anesthetic is provided that numbs the back of the throat for the entire procedure. If needed, your physician can collect a small tissue sample for biopsy or remove obstructions such as a foreign object or polyps during a nasal endoscopy.
