Have you ever noticed that your newborn baby's lower jaw and chin are too small? Does he seem to be having a hard time breathing, especially when he is lying on his back? Does he seem to be getting a little choked up with milk? It's normal for a mother to feel scared when she sees things like this. Today we are going to talk about a rare but important condition that can cause these symptoms. We call it Pierre Robin Syndrome (PRS).
What is Pierre Robin Syndrome (PRS)?
Simply put, Pierre Robin Syndrome (PRS) is a rare birth defect that occurs while a baby is developing in the womb. Doctors sometimes call it the Pierre Robin Sequence. This condition mainly affects a baby's face, especially the mouth and jaw. These problems can make it difficult for the baby to breathe, suckle, or drink from a bottle.
Think about it, the parts of our face should develop in order. After the lower jaw is properly formed, the tongue comes into its proper place. Then the upper palate forms. But in PRS, this order is disrupted. That's why it's sometimes called "Sequence".
This condition is not very common. On average, only about one in 8,500 children has the chance of developing this condition. So don't be alarmed when you hear about this. But it is very important to be aware of this.
How do I know if my baby has PRS? What are the main symptoms?
Often, doctors can see these signs as soon as the baby is born. There are some physical changes and symptoms that are mainly seen in PRS. Let's look at them separately.
| The nature of the characteristic | Simple explanation |
|---|---|
| Major Physical Differences | |
| Small lower jaw and chin (Micrognathia) | The baby's lower jaw and chin are very small in size. This is clearly visible if you look at the profile of the face. |
| Cleft Palate | The upper part of the mouth, that is, the palate, is not completely closed. There is a gap in the middle. This allows milk to come out of the nose when you drink. |
| Tongue moving towards the throat (Glossoptosis) | Because the lower jaw is small, there is not enough room for the tongue to fit properly inside the mouth, and the tongue falls back, that is, towards the throat. This is the main cause of difficulty breathing. |
| High-arched palate | In some children without a cleft palate, the palate may be much higher than normal, like an arch. |
| Having teeth at birth (Natal teeth) | Very rarely, some children may have one or more teeth at birth. |
| Resulting Symptoms | |
| Wheezing (Stridor or Stertor) | As the tongue falls into the throat, the airway is blocked, causing a snoring or whistling sound. This sound is especially pronounced when the baby is placed on their back to sleep. |
| Difficulty drinking milk | Due to the cleft palate and the position of the tongue, the baby may not be able to latch on to the nipple properly and suck milk. The milk may also get stuck in the throat. |
| Weight gain problems | Because it is difficult to breastfeed, the baby may not receive the necessary nutrition and may not gain weight well. |
Why is this happening? What is the reason for this?
In fact, doctors still haven't found the exact cause of this, but we do know that it may be caused by several genetic mutations that occur during the baby's development in the womb.
The sequence of this is as follows:
1. First, the baby's lower jaw doesn't develop properly. It grows very small.
2. Because the lower jaw is small, the tongue has no place to rest properly, and it is pushed up and back (towards the throat).
3. The tongue comes up like this and blocks the upper airway.
4. At this point, the two parts of the baby's upper palate should be closing together. But because the tongue that has come up is crossing, the two parts of the palate cannot join together, leaving a gap in the middle.
This series of events is connected to one another, like a row of dominoes falling one after another. That's why it's also called the Pierre Robin Sequence.
Sometimes it can be hereditary. For example, PRS can occur as a feature of other genetic conditions, such as Stickler syndrome.
Is this condition dangerous? Can complications occur?
It's normal to feel scared when you hear this. PRS can range from mild to severe . At a mild level, it's not much of a problem.
However, if you have severe PRS, life-threatening complications may occur due to continued obstruction of the airway.
- Respiratory distress: Complete blockage of the airway.
- Low blood oxygen levels (Hypoxemia): Insufficient oxygen to the body.
- Pulmonary hypertension: Increased pressure in the vessels that carry blood from the heart to the lungs.
- Congestive heart failure: A condition in which the heart's function is weakened due to the strain it has to bear.
But don't be afraid of these things. If your baby has severe PRS, the doctors and hospital staff will monitor him very closely. If any complications arise, they will be ready to start the necessary treatment as soon as possible.
How exactly does the doctor find this?
Most of the time, a pediatrician can identify these symptoms during a routine checkup at the hospital after the baby is born.
If the baby has a very mild condition, it may not be noticeable at birth. However, if the baby is not gaining weight or making strange sounds while breathing, the doctor may be suspicious.
If there is any doubt, the doctor may perform these tests:
- A complete physical examination: Here, we carefully examine the three main symptoms we talked about (small chin, tongue thrust backward, cleft palate).
- CT scan (Computed Tomography scan): This helps to clearly see the structure and position of the baby's facial bones.
- Sleep study: This test is done to determine if the baby has obstructive sleep apnea (OSA), a condition in which breathing stops during sleep due to the tongue falling back.
What are the treatments for this?
Treatment depends on the severity of your baby's symptoms.
Mild PRS
Some children's condition is not so severe. As they grow older, their lower jaw also grows. When the lower jaw grows, the tongue has a place to rest, so it simply stops falling into the throat. Then the difficulty in breathing also disappears. Such children may not need any surgery.
The doctor advises you:
- Baby sleeping position: Turn the baby's head to the side and place it on its stomach to sleep. This allows gravity to push the tongue forward, opening the airway for breathing. Never put your baby to sleep in this position without the advice of a doctor.
- Special breastfeeding methods: Using special cups and bottles, and feeding the baby in an upright position is advised.
Severe PRS
If the baby has a lot of difficulty breathing and is unable to breastfeed, surgery may be necessary.
- Mandibular distraction osteogenesis: This is the most common surgery. In this procedure, the surgeon breaks the baby's lower jaw bone in two and inserts a small device between them. Then, over a few days, the device is rotated to move the two pieces of bone apart. The gap between them is then filled with new bone. This way, the lower jaw can be gradually lengthened. As the jaw lengthens, the tongue comes forward, opening up the airway.
- Tracheostomy: If breathing difficulties are severe, a small hole is made in the front of the neck and a tube is inserted directly into the windpipe to help the baby breathe. This is done to save the baby's life in an emergency.
- Tongue-lip adhesion: This is a less common procedure. In this procedure, the tip of the tongue is temporarily sutured to the lower lip. This prevents the tongue from falling into the throat. Later, when the baby's jaw grows, the sutures are cut and removed.
What should I do as a parent?
When you find out that your baby has this condition, you may feel overwhelmed with many things to think about. That's normal. Remember, you and your baby are not alone. The doctors and hospital staff are always there to help you.
They will explain these things to you:
- How to manage your baby's symptoms: You will be thoroughly explained about surgeries and other treatments, their pros and cons, so you can make the best decision for your baby.
- How to take care of your baby at home: How to put your baby to sleep, how to breastfeed, what to do in case of an emergency, etc. Don't be afraid to ask questions again and again if you don't understand.
- Support groups and services: You can find information about support groups where other parents of children with similar problems can join. Talking to someone who has been through the same thing as you can can be a great relief.
You should ask your baby's doctor these questions:
- How serious is my baby's condition?
- Does he have any other medical conditions besides PRS?
- Would you recommend surgery? Why?
Remember, there is no complete cure for this, as it is something that is inherited. But with proper treatment, the symptoms can be completely controlled and your baby can live a healthy, normal life like other children.
