Sinuses are hollow chambers formed by the bones of the face and head. Problems in the nose or sinuses can cause trouble breathing through the nose. They can cause pain and drainage from the nose. Or they can cause a loss in the sense of smell. Nasal endoscopy is a procedure that looks inside the nose and sinuses. It is often done by an ear, nose, and throat specialist called an otolaryngologist. It can help find the cause of your symptoms. It can also diagnose infections and help find structural problems in the nose. The procedure is done with a rigid or flexible endoscope. This is a thin, lighted tube with a small camera on it.
