• Adenoidectomy


    Adenoidectomy is the surgical removal of the adenoids. Adenoids are made of tissue located in the back of the nose near the throat. They are thought to be involved in developing immunity against infections in children.

    Reasons for Procedure

    Adenoidectomy is usually done to remove enlarged adenoids that are causing problems by blocking the nasal passage, or the opening to the sinuses or middle ear. It may be used to treat long-term sinus infections and recurrent ear infections or chronic ear fluid.

    Possible Complications

    Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:
    • Bleeding
    • Infection
    • Dehydration from difficulty taking fluids
    • Regrowth of adenoid tissue
    • A permanent change in voice
    • Reaction to anesthesia
    Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications such as:

    What to Expect

    Prior to Procedure

    Your doctor will likely do the following:
    • Physical exam of the tonsils, throat, and neck
    • Blood test
    • Review your medications—you may be asked to stop taking some medications up to 1 week before the procedure
    • Order x-rays
    Do not eat or drink anything for at least 8 hours prior to the procedure.


    General anesthesia is used. It will block any pain and keep you asleep through the procedure.

    Description of the Procedure

    The adenoids will be surgically removed through the mouth. A scalpel or another type of tool will be used to remove the adenoid tissue. An electrical current can also be used. Sometimes, the adenoids are removed through the nose. Gauze packs will be placed at the site of the procedure to prevent bleeding.
    Radiofrequency ablation is a type of procedure that uses heat to destroy tissue. It may be used to reduce the volume and size of the adenoids. This method often has less bleeding. It also seems to cause less pain.

    Immediately After Procedure

    You will be monitored in a recovery room until the anesthesia wears off.

    How Long Will It Take?

    Less than 45 minutes

    How Much Will It Hurt?

    Anesthesia will prevent pain during surgery. Pain and discomfort after the procedure can be managed with medications.

    Average Hospital Stay

    It may be possible to leave on the same day as the procedure. Your doctor may choose to keep you overnight if there are complications.

    Post-procedure Care

    At the Care Center
    During your stay, the care center staff will take steps to reduce your chance of infection, such as:
    • Washing their hands
    • Wearing gloves or masks
    There are also steps you can take to reduce your chance of infection, such as:
    • Washing your hands often and reminding your healthcare providers to do the same
    • Reminding your healthcare providers to wear gloves or masks
    At Home
    Recovery will take 7-14 days. After the procedure, you may have:
    • Light bleeding
    • Nasal stuffiness or drainage
    • Sore throat
    • Bad breath
    • Difficulty swallowing
    • Ear or throat pain
    • Stiff or sore neck
    • Nasal speech
    To help relieve some discomfort and speed recovery:
    • Eat light meals of soft foods for the first several days.
    • Avoid hot liquids.
    • Take prescribed antibiotics to prevent infection.
    • Take pain medication as needed.
    • Avoid swimming and rough or intense exercise.
    • Avoid forceful nose blowing.

    Call Your Doctor

    It is important to monitor your recovery. Alert your doctor to any problems. If any of the following occur, call your doctor:
    • A sudden increase in the amount of bleeding from the mouth or nose. If your child is swallowing a lot, check the back of their throat with a flashlight to look for blood
    • Redness, swelling, increasing pain, or any discharge from the nose or mouth
    • Increased swelling or redness of the eyes
    • Signs of infection, including fever and chills
    • Pain that cannot be controlled with the medications you were given
    • Noisy or difficulty breathing
    If you think you have an emergency, call for medical help right away.
