Pierre Robin Sequence (PRS) is a condition where babies are born with a cleft palate and a small lower jaw which can cause breathing and feeding difficulties in early life. This page explains how it happens, how it’s treated, and what support is available.

What is Pierre Robin Sequence?

Pierre Robin Sequence (PRS) is named after a French physician who identified the main features of the condition in the early 20th Century. It is also occasionally called Pierre Robin Syndrome.

In medicine, a ‘sequence’ is when a number of issues occur in a particular order due to a single cause. These issues are listed below.

A baby with PRS will have a lower jaw which is noticeably smaller and more receded than those of other babies. This is called ‘mandibular hypoplasia’ or ‘micrognathia’.

This smaller jaw is thought to be the cause of the other features of PRS. Thankfully, the jawbone continues to grow as children get older, so it doesn’t usually need surgical treatment.

A smaller lower jaw means a baby’s tongue will be further back than usual. This means their tongue is more likely to ball up and fall backwards into the throat, causing obstruction and therefore breathing difficulties. This is called ‘glossoptosis’.

Breathing difficulties can be very difficult to manage and cause a lot of concern, so it’s important the baby is under the care (or at least under the supervision) of a specialist hospital.

A cleft palate (or a high arched palate without a cleft) may be present, and this can affect children in different ways. Babies with a cleft palate often have issues with milk coming down their nose during bottle feeding, but this gets better as a feeding pattern is established, the child grows, and the palate is repaired.

A cleft palate (whether or not the child has Pierre Robin Sequence) can also cause hearing difficulties, so it’s important for your child’s hearing to be tested regularly. If you are under the care of a Cleft Team, this will happen automatically in the clinic. Otherwise, you will need to ask to see an ENT consultant or audiologist.

How common is Pierre Robin Sequence?

The condition is rare. Estimates range from one in 8,000 to 30,000 worldwide. In the UK statistics put it at one in 14,500 babies, or just under 50 babies per year.

Around 50-80% of these babies have other associated conditions, with the most common being Stickler Syndrome.

How does Pierre Robin Sequence happen?

A ‘sequence’ is when a single issue in development results in a chain of other issues.

In both a ‘sequence‘ and a ‘syndrome‘, different symptoms and issues are grouped together into one condition, but with syndromes these issues don’t occur one after the other in the same way.

In the case of Pierre Robin Sequence, the main feature is a small lower jaw (‘mandibular hypoplasia’ or ‘micrognathia’), which makes the tongue more likely to fall backwards and obstruct the airways, which can then stop the palate from closing properly (causing a cleft palate). These issues can happen by themselves or be seen together.

It happens very early on in pregnancy, but we don’t know for sure why it happens. Research has looked into several different possibilities, but nothing is known for sure. It’s thought that, much like cleft, there will be many different factors at play. This means it’s very unlikely to happen just because of something a parent did or didn’t do.

PRS can be a part of other syndromes or conditions with genetic links, such as Stickler Syndrome. It can be hard to diagnose PRS because of this.

How will Pierre Robin Sequence affect my child?

Most children with Pierre Robin Sequence grow up normally, even if they start their lives with quite severe problems. 

All babies with Pierre Robin Sequence will have some difficulties, but these will vary from child to child.

  • Some have no problems with breathing and only minor feeding difficulties. These babies can usually go home shortly after birth.
  • Others have moderate difficulties, which may mean they have to stay in hospital until breathing and feeding patterns can be established. They may need to use a feeding tube (nasogastric or NG tube) for a while at home.
  • A smaller group of babies have major difficulties with both feeding and breathing, and these can persist for several months and require a nasal prong or even a tracheostomy. This can be very difficult to cope with, so it’s important parents and families get the right support and remember that these issues will improve with time.

All babies born with PRS need to be carefully investigated and monitored to make sure they can continue to take in enough oxygen. Parents need help and advice about the right feeding bottles and positions for feeding, which should be given by experienced professionals. This help can come from a Cleft Team, a specialist health visitor, a speech and language therapist, a feeding clinic, or a combination of the above.

In most cases, your child’s chin will grow forward as they get older. The final position of the jaws has more to do with genetics than the Pierre Robin Sequence. The change is gradual, with improvement in the first year but continuing through childhood.

Advice for parents and families:

  • Remember that whilst the first year of your baby’s life may have more challenges than you expected, things will get easier as your baby grows up.
  • It’s important that you get expert advice on feeding and on positioning for both feeding and sleeping from a specialist health professional who understands PRS. Advice for babies without PRS won’t always be relevant and may be harmful.
  • You may find yourself needing to juggle appointments with many different specialists. This can be difficult to manage, and you will have to be more proactive to ensure your baby is seen by the right people at the right time. Keeping good records and writing down any questions or concerns you have will help with this.
  • Don’t forget that any new baby is tiring, and a baby with Pierre Robin requires a lot of extra attention. It is important to look after yourself as best as you can, as this will make you better able to care for your baby. Ask what, if any, provision that your local council offers such as short break care. You may also wish to look into financial support to help with extra needs.

Some of CLAPA’s Parent Supporter volunteers have babies with PRS. If you need to talk, don’t hesitate to get in touch.

Back home, we (I in particular) struggled with our new role as carers as well as parents. It was not the start to motherhood I had expected. One of the worst things was her feeding tube. We had a complicated relationship! I hated how I had to tape the tube to her face, how she screamed when it was put in and how it complicated her reflux. But I loved it as it kept my daughter alive. It often came out, which meant frequent trips to the children’s ward (often at night) so it could be put back in. A milestone for me was the day I learnt how to put her feeding tube in myself.

How is Pierre Robin Sequence treated?

The jaw bone continues to grow during childhood and is usually fully grown by adulthood, so it’s the other elements of Pierre Robin Sequence – namely the breathing difficulties and cleft palate –  that need to be managed.

The below section goes through the different elements of PRS and how they are typically managed. Your medical team will give you specific expert advice on caring for your baby, and the general information on this page should never replace that advice.

Remember to speak up if you are worried about something! You are around your baby constantly and know them better than the health professionals, so if you think something is wrong it’s best to be safe and mention it.

It is vital that babies born with PRS get the care and supervision they need early on. This care should be provided by professionals who have experience of the condition, and it should be carried out (or at least coordinated from) a specialist hospital, especially during the first few weeks.

Ideally, this should be an established Cleft Team which includes a specialist paediatrician. This arrangement is much better for parents and children because of the expertise within the team, and this way appointments can be arranged as one long visit rather than several visits to individual specialists.

If for whatever reason your child is not under the care of a Cleft Team, you will need to see the following specialists at some point:

  • Otologist
  • Audiologist
  • Dietician
  • Specialist Health Visitor

You may need to ask for your child to be seen by these specialists. Do not assume that you will automatically be referred.

As Stickler Syndrome is so common in babies with PRS, your baby must also be seen by an ophthalmologist for frequent eye checks.

It’s best if you have a paediatrician who can look after all aspects of care, be alert for additional problems such as Stickler Syndrome, and refer you to various specialists when appropriate.

Seeing all these health professionals can be quite stressful for both parents and children. To make these experiences more positive and productive, try to make notes of points you wish to discuss and questions you’d like to ask, and make sure to ask for clarification if you don’t understand something that is being said. Keeping good records (such as copies of letters, dates of appointments, and names of specialists) will also make the entire process easier to manage.

All babies with Pierre Robin Sequence are assessed by a specialist nurse to establish the safest method of feeding.

Some babies need more assistance than others due to reflux and breathing difficulties. An individual plan will be put into place for your child which may include a nasogastric (NG) tube, a thin tube which goes in through the nose and into the stomach. It’s the most common method of feeding babies who, for whatever reason, can’t get enough nutrition orally.

Not all babies with Pierre Robin Sequence need a nasogastric tube, and for those that do it’s usually gone by the time they are a year old.

Establishing feeding with a bottle takes time, patience and experimentation depending on the degree of your baby’s difficulties. This includes finding a bottle and a position which suits your baby. All babies should be offered bottle feeding as early as possible (along with tube feeding where necessary) to establish an association between sucking and receiving food. Hospitals should establish a good feeding pattern before any baby born with Pierre Robin Sequence is discharged home. Parents need expert advice and help from specialist feeding nurses, specialist health visitors and speech and language therapists to help them once the child is home.

Breathing and feeding can require a big effort for many babies with Pierre Robin Sequence, so weight gain can be slow. To help with loss of calories, supplements can be added to feeds under the instruction of a dietician, or high calorie milk can be recommended.

Babies with a cleft palate can have a lot of issues with wind, and babies with PRS can gag and vomit easily, possibly due to the position of the tongue.

Feeding Equipment

There are various types of specialist bottles and teats available from CLAPA. Your Cleft Nurse or another medical specialist should advise you which bottles and teats to get.

In some cases, parents and carers are advised to try the ‘Haberman Feeder‘. This is a specialised bottle that was designed by a mother of a child that was born with Pierre Robin Sequence. It is designed to help any baby that has a weak sucking reflex. It is more expensive than other bottles but has been very successful for some babies whose degree of difficulty with sucking has been great. They are available from:

Athrodax Healthcare International Ltd
Hawthorne Business Park
Drybrook
Gloucestershire
GL17 9HP

Tel: 01594 544440

UK parents can get a reduced rate for this bottle as they can claim back the VAT. This exemption is because ‘your baby has a feeding difficulty’ and therefore this type of bottle has zero tax. On receipt of an order form, cheque and VAT form, Athrodax aim to send your order by return post. Credit card orders can be taken but they will be subject to VAT.

CLAPA holds a small emergency stock of complete Haberman bottles but we do not stock the replacement valves and teats, these will have to be purchased from Athrodax directly. Contact us if you need one of these bottles.

Your medical team will give you expert advice on feeding and weaning your baby. The information here is general only.

It is often recommended that babies with PRS start on solid food, such as baby rice, at around four months because they may find it easier to cope with food than with liquids.

As with all babies, solid food should be pureed initially and lumps introduced very slowly to enable you baby to learn to cope with them, otherwise they may gag.

It is important for you baby to experience chewing as it is thought to be a prerequisite for speech development. Teething rings may also be useful.

As always, discuss what is best with the health professionals looking after your baby. Whatever method is chosen, time, patience and a comfortable chair will be needed.

Some babies with Pierre Robin Sequence have very few problems with breathing. However, it is generally advised that babies with PRS are nursed on the side or towards the front rather than on their back.

This is contrary to the advice for most babies, but for babies with PRS it means their tongue is less likely to fall back and block their airways. Remember this is general advice only, and advice for your baby’s situation should always be sought from a specialist.

While travelling, it is recommended that your baby is positioned as upright as possible. If they need to lay on their side, they may need to travel in a carry cot.

You can also buy special car seats for babies that lay flat and allow your baby to travel in a prone position (lying on their front). These are similar to carry cots and can be quite heavy, but can also be adapted to a pushchair.

Occasionally a small tube needs to be passed through the nose, behind the tongue, to improve breathing. This is called a nasopharyngeal airway or nasal prong.

In severe cases, one option is to lengthen the jaw by a technique known as mandibular distraction which gradually moves the jaw bones into a different position over time.

Finally, a very small number of babies with major problems with their breathing require tracheostomies, which is when an opening is created at the front of the neck so a tube can be inserted into the windpipe.

It is very difficult for a baby with Pierre Robin to lay on their back as this can cause their tongue to fall back and block their airway.

The ‘Safe to Sleep‘ campaign to reduce cot death advises that babies sleep on their back and play on their front, but this does not apply to babies with Pierre Robin Sequence.

The exact right position for a baby with Pierre Robin depends on the severity of the breathing difficulties and how they are being managed; most babies with PRS are nursed on their side.

Advice should be sought from a medical specialist who will take all the factors involved into consideration.

If a cleft palate is present, a palate repair operation is needed. This usually happens between 6-12 months, but may be later depending both on the severity of the breathing difficulties and on the preferences of the surgeon.

There is a bit of a debate about the best time to repair a cleft palate with Pierre Robin Sequence. The problem is that repairing the palate may temporarily make breathing worse.

Some surgeons prefer to do the procedure at the usual time (from 6 months old) and accept that there may be some breathing issues which need to be managed until things get back to normal.

Other surgeons prefer to wait for the jaw to grow in the hopes that breathing will naturally get better and therefore reduce the chances of further breathing problems after surgery.

There are benefits and drawbacks to both options. Your surgeon will explain what they think is the right way forward for your baby, and will answer any questions or concerns you may have.

About the cleft palate repair operation

The procedure will usually take between 1 ½ to 3 hours, depending on the extent of the cleft, and babies will usually stay in hospital for at least two days afterwards.

Feeding may take some time to be re-established after cleft palate repair but in most cases should be re-established in one to two weeks.

Because the clefts in babies with Pierre Robin Sequence tend to be very wide, it is very often necessary for relaxing cuts to be made on the side of the palate, but these heal very quickly. There is also an increased risk of developing a small hole in the repair (fistula). These holes sometimes heal by themselves, but sometimes a further small operation is needed.
