Adenoids are similar to tonsils in that they can cause painful symptoms if they become enlarged or infected. Adenoids are made up of lymph tissue that is located in the space above the soft roof of the mouth. Unlike tonsils, they are not visible by looking in your nose or throat with a light. To diagnose adenoiditis a physician will ask about your symptoms and view the adenoids through a small endoscope. Depending on the severity of inflammation and symptoms a doctor will recommend treatment ranging from antibiotics to adenoid removal. Adenoid removal surgery, called an adenoidectomy, is an outpatient procedure. Typically patients can return to normal activities within 1-2 weeks.
