An adenoidectomy is an operation to take out the adenoids. These are small nodes at the back of your child’s nose that trap and destroy germs.

This operation can help your child if they get regular ear infections, snore, or get sinusitis – a swollen or blocked nose. We do it under general anaesthesia.

What to expect

Before the operation

You can give your child pain relief like paracetamol before the operation. Make sure you don’t give aspirin for 2 weeks before the operation as it can increase bleeding.

During the operation

Your child will be in the operating theatre for between 45 minutes and one hour. This includes the anaesthetic, operation and time in the recovery room.

After the operation

After the operation, your child will return to the ward for observation for 4 to 6 hours. Your doctor will decide if they need to stay in overnight.

There's a low risk of bleeding for up to 14 days after the operation. Bad breath is normal and should pass in a few days.

Care at home

Pain relief and antibiotics

It’s important to give pain relief like paracetamol every 4 to 6 hours for 2 full days. Check the packaging to find out the right dose for your child’s age and weight. Record the time that you give each dose.

Your child might have a slight temperature after the operation. Pain relief medicine can help with this.

Make sure you don’t give your child aspirin for 2 weeks after the operation as it can increase bleeding.

If your child is given antibiotics, it’s important that they take them all.

Eating and drinking

After the operation your child might not want to eat. If they’re hungry, they can have something light. Most children start eating normally the next day.

If your child feels sick or is vomiting, stop food and fluids for one hour. After this, have them sip clear fluids and eat a small amount of dry food, like plain toast or a biscuit.

Returning to school, sport and activities

Your child may be able to return to school or childcare the day after the operation. Let their carers and teachers know that they may feel tired.

It’s best to limit strenuous activities like sport for 10 to 14 days.

When to seek help

See your GP or go to the nearest emergency department if your child:

  • is bleeding
  • feels unwell
  • isn’t drinking
  • has a slight temperature that increases.

If you're not sure whether to go to an emergency department, call 13 HEALTH (13 43 25 84) and speak to a registered nurse.

In an emergency, call Triple Zero (000) and ask for an ambulance.
