An adenoidectomy is a surgical procedure to remove the adenoid, a gland located behind the nose and soft palate that helps the immune system fight infection.

The adenoid produces white blood cells, but frequent upper respiratory infections can cause the adenoid itself to get infected and enlarged. An enlarged adenoid can interfere with breathing and swallowing, block the Eustachian tubes and cause frequent ear infections.

The adenoids are usually removed through the mouth while the patient is under general anesthesia.
