A rigid or flexible lighted instrument is placed in the nose after anesthetic spray is used to get a better look at the opening to the sinuses and look for swelling in the nose, areas of obstruction due to a septal deviation or presence of polyps. One can look for pus coming out of a drainage area for a sinus also. If a sinus has been surgically opened in the past, endoscopy can help to determine if it is still open and if there is pus in the sinus. Typically, endoscopy is not necessary in a patient with classic signs and symptoms of acute non-complicated sinusitis.
