Tongue reduction surgery

This page explains tongue reduction surgery, what to expect when your child comes to Great Ormond Street Hospital (GOSH) for the operation and provides practical advice on preparing your child for the surgery and recovering afterwards.

Some children have a large tongue (macroglossia). It can cause difficulties with feeding, breathing, drooling, speech, the position of the teeth and jaw and may affect your child’s facial appearance. Tongue reduction surgery will help overcome the difficulties caused by having a large tongue by making it smaller. The decision as to whether your child will benefit from surgery is made by a team of specialists, which includes a surgeon, a specialist speech and language therapist and an orthodontist if your child has teeth present.

The speech and language therapist will assess the effect of the large tongue on your child’s feeding skills, speech and mouth movements and an orthodontist will assess your child’s teeth and jaws.

Is there anything that I should do before the operation?

Your child will not be able to suck from a bottle or breast feed immediately after the operation while the tongue is healing so it will be helpful to get them used to an open cup and not dependent on a bottle. It would also be an idea to get them to try taking liquids from a medicine syringe and a soft silicone-tipped spoon, as they might find these easier ways to drink after the operation initially.

Your child should also be comfortable with having smooth puréed foods (such as smooth yoghurt without bits) as this will be the texture offered in the days after surgery. It will also be helpful for your child to be used to drinking water as water is used to keep the mouth clean. If your child sucks a dummy or pacifier, it is recommended that they are weaned off this prior to the operation.

What happens before the operation?

You will receive information on coming into hospital with your . You will need to bring your child for a pre-admission appointment.The purpose of the appointment is to make sure your child is fit for surgery, any tests required are done and paper work completed. The medical staff will explain the operation in more detail and discuss any worries you may have. If this hasn’t been possible then you will need to bring your child for a pre-admission appointment.

Your consent for the operation will be taken at the pre-admission appointment if this has not already been obtained. Where possible, we advise you to keep your child away from people who have colds, flu or other infections in the weeks running up to the operation. This will reduce the chance of the operation being postponed if your child is unwell.

What does the operation involve?

The surgeon will carry out the operation while your child is under a general anaesthetic. The operation will usually last for under an hour, but you should expect your child to be away from the ward for about two hours, as time is needed before the operation to prepare them for the anaesthetic, and afterwards until awake.

The surgeon reduces the size of the tongue using a keyhole procedure. The wound is closed with dissolvable stitches and four weeks to gradually disappear.

Are there any risks?

Swelling of the tongue can occur in the first few days after the surgery. This can occasionally make breathing difficult. The ward staff will monitor your child’s airway after the operation.

Infection and bleeding can occur. Antibiotics may be given at the end of the operation to prevent infection occurring. Increased saliva in the mouth after the operation can give the impression that there is more blood than there actually is.

There is also a small chance that some of the stitches may come undone. If this happens, a doctor will decide if another short operation is needed to re-stitch the tongue. If this happens it should not cause any long-term problems.

How will my child eat and drink after the operation?

If your child drinks from a bottle with a teat or is breast fed, this will not be possible for at least a couple of weeks after the operation because they will not be able to suck while the tongue is healing, as it is swollen. A feeding tube called a nasogastric tube (NG tube) is passed through the nose to the stomach in theatre. Your child may be given liquid and pain relief via the NG tube for the first few days after surgery. It is a good idea to keep the tube in place until your child is eating sufficient quantities by mouth before removing the tube.

When your child is ready, they may find it easier to drink from a medicine syringe, medicine cup or sports water bottle or sometimes liquid from a soft, silicone-tipped spoon may be best.

Runny purées from a spoon are the easiest food to eat after the operation. Please bring a variety of favourite foods such a fruit/vegetable purées, yogurt, jelly, custard and so on. You will also need a soft spoon with a deep enough bowl to hold a runny purée. Salty and acidic food should be avoided as these can cause discomfort.The temperature of food should also be cool to lukewarm in the first three to five days while the tongue is healing.

It will also help if you bring the spoon, bowl and cup that your child usually eats from, as familiar things will be comforting after the operation. Feeding will take much longer for a number of days following the operation. It may be best to give your child smaller meals more frequently. Try to keep mealtimes calm and relaxed and do not force your child to eat. If you are at all worried about feeding your child after the operation, please ask us to help.

It is advisable to have a smooth purée for the first week and a smooth diet for the second and third week.See our later list of food suggestions.

It will also help if you put your child’s baby bottle temporarily out of sight until your child’s tongue has healed enough for your child to be able to drink from the bottle without it hurting.

When their tongue has healed sufficiently to be given the bottle again, it will help if the bottle is a soft silicone squeezy one such as a MAM® or Vital Baby® Nurture bottle with your child’s normal teat. At first, gently squeeze very small amounts of liquid, pausing between each squeeze to give your child time to swallow. If your child coughs or shows any sign of discomfort during bottle feeding, stop and return to other methods of giving your child liquid.

What medications will my child receive?

Your child’s tongue will be sore after the operation, but the ward staff will monitor your child’s pain on a regular basis and give the appropriate medication. Pain relief medicines will be given at regular intervals for approximately one week. The recommended pain relief is usually a combination of ibuprofen and paracetamol taken at different times. If stronger pain relief, such as morphine, is required, ward staff will arrange this.

Pain relief should be given 30 to 60 minutes before a feed to make eating and drinking more comfortable. If your child has a preferred brand of ibuprofen or paracetamol, please bring this with you. Your child will need to continue pain relief at home until their routine returns to normal.

What else can I expect after the operation?

  • Drooling will be increased for at least a week after the operation. It is a good idea to bring lots of bibs, muslin cloths, wipes and tissues to hospital.
  • The tongue will be swollen and not very mobile after the operation until it has healed.
  • Your child’s lips can become very dry so bring some lip balm.
  • Your child’s mouth will need to be cleaned regularly after the operation, but this is usually just done with water to dislodge any leftover milk or food particles. Water in a medicine syringe is often a good way to do this.
  • It can be difficult to brush your child’s teeth initially. If possible, use a mouthwash for the first week so that sutures are not rubbed by the brush. On the ward you can also use a mouthcare pack.
  • It is normal for your child’s mouth to smell for one to two weeks after surgery as this is due to the healing process.
  • Once your child is eating and drinking normally and the tongue is recovering well, you and your child will be able to go home. Most children stay in hospital for approximately five days. Some children stay in hospital longer than this.
  • If your child has morphine, this can sometime cause the face to be itchy. The hospital staff can give you medicine for this.
  • Your child may have constipation and wind after the operation. Ask the ward staff for help if this happens.
  • The tongue will be slightly thicker after surgery. This is expected following this type of surgical procedure, even after the swelling has reduced.

When you get home

Your child may feel uncomfortable for a while after returning home but this will gradually improve. They may need continued pain relief before eating. Keep your child away from anything hard that could end up in their mouth, such as pens, keys or even hard, plastic play figures. This can be painful and could damage the healing of the operation site.

Your child will need a one week postoperative check. You can come back to GOSH for this or if you live a long way from the hospital, your family doctor (GP) may check the wound to ensure it is healing well. You can also email photos to to be reviewed by the team.

Your child will need to come back to hospital approximately 12 weeks after the operation to check the outcome of the surgery. This appointment is to see the team who will check the tongue. Following this, at approximately six months after the operation, you will see the speech and language therapist who will assess your child’s feeding, speech and mouth movements. We will send you details in the post.After these post-op appointments your child will then be reviewed at ages four and a half years, six years, nine years, 12 years and 16 years.

You should call the hospital if:

  • Your child is in a lot of pain and pain relief does not seem to help
  • Your child has a temperature of 38°C and paracetamol does not bring it down
  • You are concerned about the amount your child is eating and drinking
  • You notice discharge or bleeding around the wound
  • The wound site starts to open or there is an unpleasant odour.

Top 10 tips for restarting feeding after tongue reduction surgery

  1. Bring a silicone-tipped spoon with you to hospital
  2. Wait until your child is alert and interested in having some food!
  3. Pain relief should be given up to an hour before each feed or drink. Ensure you follow the prescription guidelines.
  4. Thin purées only, which have no ‘bits’ and are not sticky in the mouth. Avoid spicy and salty food. 
  5. Stick with foods and tastes that you know your child likes.
  6. Tiny mouthfuls at a time! Start with swipes of purée on your child’s lips and sides of tongue.
  7. Give plenty of time to swallow. Parents can eat their meal at the same time to help normalise eating. Breakfast is a good one to try.
  8. Eating and drinking will take much longer – this is to be expected!
  9. Leave the baby bottle at home! By the time of surgery, your child will be used to having sips from a cup (a spouted cup with no valve or an open cup such as a Doidy® cup). You may also use a sports bottle or even a medicine syringe if your child is not content with a cup.
  10. Read the BWS information sheet on feeding given by the Speech and Language Therapist or CNS for more details.
