Adenoidectomy is the process of taking out a person's adenoids from the back of their throat through the process of surgery. They may be removed for several reasons, including difficulty breathing through the nose and having ear infections. The surgery is common in young kids. The procedure is usually performed using a substance called anaesthesia (Greek for "without sensation"), and the substance puts a person to sleep when it is applied. Recovery time from the operation can vary from several hours to a few days.
