Tonsillectomy FAQs: Signs your child needs their tonsils out

Some adults may remember a tonsillectomy (the surgical removal of the tonsils) as a rite of passage in childhood. While a tonsillectomy is still one of the most common surgical procedures for children, they are performed less frequently than in the past.

We answer common questions parents have about tonsillectomies in children, including when surgery is needed and what to expect before, during and after the procedure.

When should a child have their tonsils removed?

The two most common signs a child needs their tonsils removed is when the child has recurrent strep throat infections or obstructive sleep-disordered breathing.

• Recurrent strep throat infections – If your child has had seven strep throat infections in one year; five infections a year for two years in a row; or three infections a year for three or more years, your pediatrician will likely refer you to an ENT surgeon for evaluation.

• Obstructive sleep-disordered breathing (oSDB) – Also known as obstructive sleep apnea, oSDB is more than loud snoring. It can cause a child to stop and start breathing several times during the night and lead to serious health issues, including weight gain, pulmonary hypertension, behavioral problems and trouble paying attention.

Less common reasons a child may need a tonsillectomy include:

• Peritonsillar abscess – A complication from an untreated strep infection that causes a pus-filled pocket to form near one tonsil. It is more likely to recur unless tonsils are removed.

• Dysphagia – Difficulty swallowing due to large tonsil size

Reasons your child doesn't need tonsils taken out include bad breath and large or swollen tonsils.

Tonsil size alone is not an indication for surgery. Although tonsillectomy is generally safe, it is still a surgical procedure and the decision is based on whether the potential benefits outweigh the risks.

At what age can a child have a tonsillectomy?

A child at any age can have a tonsillectomy if the indications are severe. However, surgeons generally wait until children are 3 years old to remove tonsils because the risk of dehydration and bleeding is greater among small children.

Is a tonsillectomy safe?

A tonsillectomy is generally considered to be a safe procedure. As with any surgical procedure, there are risks associated. The most common risks include bleeding and dehydration.

How much bleeding is normal after a tonsillectomy?

Bleeding is most common within 24 hours after the surgery and then again anywhere from 5-14 days when scabs come off after surgery. Most of the time, children and parents aren't even aware there is bleeding. It can irritate the throat and stomach and cause children to vomit, which is when parents usually become aware there is bleeding.

While bleeding can be alarming, it is usually short-lived. However, it does require medical attention to rule out complications. Severe or ongoing bleeding that does not stop requires emergency care. In other cases, contact your child’s surgeon to determine whether further evaluation is needed.

How can I encourage my child to drink after a tonsillectomy?

Children may be hesitant to drink after surgery because of throat pain. It's important for them to drink regularly so they stay hydrated, which can help the healing process.

Dr. Coffey shares several do's and don'ts with parents to help encourage fluids after surgery:

• Do set a timer once or twice an hour the first few days after surgery so parents and kids remember to take a few sips

• Do offer popsicles

• Do offer water or 100% juice

• Do give small amounts of water by syringe like medication if refusing to drink

• Don't offer thick drinks like milkshakes unless using a spoon

• Don't use straws or sippy cups as suction can irritate the throat

How can I help relieve my child's pain after a tonsillectomy?

A sore throat and pain are the most common side effects of a tonsillectomy. Regular fluids can help ease a sore throat and pain, in addition to keeping kids hydrated after surgery.

Over-the-counter pain medicine is also effective pain relief after tonsils are removed. You can alternate children's acetaminophen (such as Tylenol) and a non-steroid anti-inflammatory (such as ibuprofen) to help control pain. Be sure to follow your surgeon or nurse's dosing instructions, including the amount and frequency.

How long does recovery take after a tonsillectomy?

Generally, most children are back to normal about 10 days after a tonsillectomy.

The first few days after surgery require the most care, with a focus on keeping children well hydrated and limiting physical activity.

Your child should avoid contact sports or heavy physical activity for two weeks after surgery because of the risk of bleeding.

Children can return to school once the throat is completely healed, which can be anywhere from 10 days to two weeks. Your surgeon can help you determine the schedule that's right for your child and family.
