Adenoidectomy

An adenoidectomy is an operation to remove enlarged adenoids.

Adenoids are small lumps of tissue at the back of the throat behind the nose. They're part of the immune system and help fight infection.

Why an adenoidectomy is done

An adenoidectomy is mainly done in children to help with problems caused by enlarged adenoids.

These problems can cause pain or partially block the airway. They include:

• difficulty breathing through the nose, which can cause mouth breathing or snoring
• sleep apnoea , where breathing stops and starts during sleep
• glue ear , an infection in the middle ear which can cause hearing problems
• frequent ear infections

The adenoids usually start to shrink around the age of 4 and disappear by early adulthood.

Your doctor might suggest waiting to see if these problems get better by themselves rather than having an adenoidectomy, depending on how serious the problems are.

An adenoidectomy may be done in adults who have these problems, but this is not common.

What happens during an adenoidectomy

Your child will not be able to eat or drink for some time before having an adenoidectomy. The hospital will give you information about this.

The operation is usually done as a day case. This means your child should be able to go home on the same day once they're well enough.

It's done under general anaesthetic , so they'll be asleep during the operation and will not feel any pain. It usually takes about 30 minutes.

The surgeon removes the adenoids through the mouth. They will either be carefully cut out or removed using special tools that apply heat or radio frequency energy.

Dissolvable stitches may be used to stop any bleeding.

The process is the same for adults having an adenoidectomy.

An adenoidectomy may be done at the same time as a tonsil removal (adenotonsillectomy) or surgery to put a small tube in the ear to drain fluid (grommet surgery).

After the operation

Your child will spend some time in the recovery room and have medicine to help with pain and swelling.

After the operation they may:

• feel sick
• have a blocked nose
• have a sore throat and sore ears
• have a temporary change to their voice – it may sound like they are talking through their nose
• have bad breath

Recovering from an adenoidectomy

It usually takes about a week to recover from an adenoidectomy. There are things you can do to help your child recover afterwards.

Possible complications of an adenoidectomy

An adenoidectomy is a common and straightforward procedure.

Complications are rare but can include:

• bleeding in the throat after the operation, which may need a second operation to stop it
• damage to the teeth – the surgeon might chip or knock a tooth, especially if they're already loose or capped (let the hospital know if your child has any teeth like this)
• infection where the adenoids were removed – antibiotics can help with this
• problems breathing because of swelling in the throat
• changes to the voice, but it should go back to normal after a few weeks
• breathing problems or infections still happening after the operation
• the adenoids growing back, but this is not common
