Have you ever noticed that some babies' heads are not round, but rather elongated and narrow? Like a boat, or the top of an egg. It's normal for parents to get a little worried and scared when they see this. "Is something wrong with my baby?" You may think. It's important to be aware at times like these. Today we're going to talk about one of the main reasons why the head shape can change in this way. In medicine, we call this Scaphocephaly , or Sagittal Craniosynostosis .
What is Scaphocephaly? Let's understand it simply!
Okay, now let's see what this is in simple terms. A baby's skull is not made up of a single bone. The skull is made up of several pieces of bone. It's like a puzzle piece being put together. There are small gaps, or sutures, between these bone pieces. These sutures allow the baby's brain to grow and expand as it grows. Imagine, these sutures are what give the skull "flexibility."
Scaphocephaly is a condition in which the main suture on the top of a baby's head, specifically the front-to-back suture (sagittal suture) , closes quickly , either before or after birth. The sagittal suture usually begins to close completely around the age of 22, and it doesn't close completely until between the ages of 30 and 50. So imagine what happens when a suture that should have been open for so long closes at a young age.
When this suture closes so quickly, the skull loses its ability to grow in both directions. But the brain continues to grow. Then the skull has to grow only lengthwise. That's why the head takes on a long, narrow shape. It's like the shape of a boat, or like an egg turned on its side. It may be a little wider in the front, and narrower toward the back, like a rounded tip.
At times like this, doctors usually recommend surgery within the baby's first year to allow the brain to develop properly.
Is this condition called scaphocephaly dangerous?
Yes, sometimes this can be dangerous . As we discussed earlier, when the bones of the baby's skull fuse together too quickly, the skull cannot grow larger on both sides. But the brain continues to grow. What happens then? Pressure on the brain begins to build up inside the skull. If this pressure continues, it can affect the baby's brain growth and overall development. Therefore, if this is not treated in time, there is a possibility of problems with the baby's growth and development.
How common is this condition?
Scaphocephaly is a condition that belongs to a larger group called craniosynostosis . Simply put, craniosynostosis is the premature closure of one or more of the sutures in the skull. According to statistics in the United States, it is estimated that craniosynostosis affects about one in 2,500 live births.
Of these types of craniosynostosis, scaphocephaly (Sagittal Craniosynostosis) is the most common type . About 53% to 60% of all children with craniosynostosis suffer from this condition. This means that it is not that uncommon.
What are the symptoms of this scaphocephaly condition?
The main symptom is that the baby's head is abnormally shaped . As the baby grows, this change in shape becomes more apparent. You may notice a ridge on the top of the baby's head where the sutures are closed. Normally, a baby's head has a soft spot called a fontanelle , but instead of that, there is a ridge like this.
Your baby's head isn't round like you'd expect. Instead, when viewed from above, it's narrow and long . It's like the shape of an egg. A baby's face can usually be round, but as the sides of the head move back, it becomes elongated and narrow.
Imagine, some mothers first notice this difference when they are bathing their baby and touching their head. They may think, "Oh, doesn't the top of my baby's head look a little higher than the rest of the body? It feels strange to the touch too."
Why does scaphocephaly occur? What are the causes?
Scaphocephaly occurs, as we mentioned earlier, because the sagittal suture in the baby's skull closes too early. The baby continues to grow even after this suture closes. That's why the head has an unusual shape.
It's still not completely clear why this seam closes so quickly, but research has found that environmental and genetic factors may play a role.
There are some genetic variations (Genetic variants / Mutations) that doctors have identified as being associated with the condition scaphocephaly. For example:
- `SMAD6`
- `TWIST1`
- `TCF12`
- `ERF`
- `MSX2`
But not all cases of scaphocephaly are inherited from a child's parents. Sometimes these genetic changes can occur randomly, without any apparent cause. Roughly speaking, only about 10% of children with scaphocephaly have a clear genetic cause.
Also, sometimes scaphocephaly can occur as a symptom of another underlying genetic condition .
What are the risk factors for scaphocephaly?
In some cases, a child may be at increased risk of developing scaphocephaly. Here are some such risk factors:
- The mother may have taken certain medications during pregnancy, such as valproic acid (a medicine used to treat conditions such as epilepsy).
- Maternal use of tobacco products during pregnancy.
- The child's father is over 40 years old.
In addition, it has been found that males are more likely to develop scaphocephaly than females.
What are the possible long-term effects if left untreated?
If scaphocephaly is severe or not treated properly , the pressure inside the baby's skull (intracranial pressure) can increase. This is because the brain continues to grow even though the skull is closed. This increased pressure can damage the baby's brain. It can also cause conditions like:
- Developmental delays: Things like talking, walking, and crawling may be delayed.
- Seizures: We also call them " convulsions ".
- Vision problems.
Therefore, if you have any doubts about this condition, it is very important to seek medical advice immediately.
How does a doctor diagnose this?
A doctor usually diagnoses scaphocephaly at birth, or during a routine checkup at a well-child clinic . When examining the baby, the doctor will do the following:
- Carefully observe the shape of the baby's face and head.
- They feel the top of the head, where the sagittal suture used to be. They look to see if there is a raised lump there, instead of the normal softness.
- The baby's head is measured. This can help determine the severity of the condition.
In addition to this physical examination, imaging tests of the skull may also be performed to confirm the diagnosis. For example:
- X-ray examination (X-ray)
- MRI scan
- CT scan
These tests can provide a clear picture of the bones and sutures of the skull.
How do I know if my baby also has scaphocephaly?
Many parents first suspect this when they see, "Oh my baby's head isn't round." That's usually the first sign of this condition. If you feel your baby's head and notice that there's no soft spot (fontanelle) but a raised bump instead, that could be another sign.
The most important thing is that if you have any doubts or feel anything strange about the shape of your child's head, talk to your child's doctor about it immediately. Don't panic, seek advice from your doctor.
How is scaphocephaly treated?
The main treatment for scaphocephaly is surgery . This surgery involves removing the sutures that have quickly become fused together, or in some cases, reshaping the baby's skull. This surgery is usually very successful in restoring the shape of the baby's head and allowing the brain to grow properly. A doctor usually recommends this surgery when the baby is between 3 and 6 months old .
Your doctor will help you decide whether your child needs surgery. This decision usually depends on factors such as:
- The child's symptoms or complications.
- The shape of the child's head and the parents' concerns about it.
- Severity of the condition (Mild to severe). Sometimes this can be mild or severe.
Types of scaphocephaly surgery
There are three main types of surgery for scaphocephaly:
1. Strip craniectomy (or endoscopic surgery): This is a minimally invasive surgery. That is, it is performed without a large incision, but rather through two small incisions, using a device called an endoscope with a camera. Through this, the surgeon removes a strip of bone that includes the sagittal suture that has quickly closed. Sometimes, a few small strips of bone may also be removed from the sides of the skull to help the brain expand.
2. Spring-assisted surgery: This is similar to the strip craniectomy. The surgeon removes a strip of bone from the baby's skull and inserts a series of special metal springs into the gap. These springs gradually widen the gap in the skull as the brain grows.
3. Cranial vault remodeling (open surgery): This is a slightly more complicated procedure . In this procedure, the surgeon makes incisions in the baby's skull and removes the sutures in the skull. Then, the skull bones are reshaped and reattached using special plates, screws, sutures , and sometimes bone grafts . This can greatly correct the shape of the head.
Depending on the type of surgery performed, the child may need to wear a special medical helmet for several months or even a year . This helmet helps guide the skull to develop into the correct shape.
What are the risks of scaphocephaly surgery?
As with any surgery, these surgeries can have some risks. Some of them are:
- Air embolism (air bubbles entering the baby's bloodstream)
- Asymmetry, bone defects or bone irregularities of the skull
- Bleeding (wound dehiscence), excessive bleeding (may require a blood transfusion)
- Cerebrospinal fluid leak
- Infection
- Blood clot `(Embolism)`
- Blood collection `(Hematoma)`
- Need for a second surgery
- Seizures
Although these complications are very rare , they can sometimes be life-threatening and lead to premature death . The risks are slightly higher with open surgery than with endoscopic surgery.
But don't worry. Your child's doctor will explain all these risks to you before the surgery. Your child's surgical team is highly trained and experienced in these types of surgeries. They will take the utmost care to prevent these complications and ensure your baby's safety.
When should I see a doctor?
If you think your baby's head isn't round, tell your child's doctor right away . Also, if your child isn't meeting developmental milestones (for example, if they're late in saying first words, crawling, or standing up), see a doctor.
If you are expecting another child, talk to your doctor about genetic counseling . A genetic counselor can test for specific genes associated with the condition. This can help you understand your risk of having another child with scaphocephaly.
What questions should I ask my doctor?
If your child has scaphocephaly, you can ask the doctor questions like these:
- Does my child need surgery?
- What are the risks of surgery?
- How should I care for my child at home after surgery?
- What symptoms should I be especially aware of?
What is the outlook for scaphocephaly?
Scaphocephaly does not improve on its own . Most children who need surgery have it done within the first year of life. Surgery is usually very successful in restoring the shape of the child's head. However, even with surgery, some children may experience developmental delays .
By diagnosing the disease early and starting treatment early, you can achieve better outcomes for your child.
As the child grows, a doctor should continue to monitor the child's head to ensure that it is developing as expected.
Early intervention services are available to help your child with learning and daily activities. These programs provide a variety of support services, such as speech therapy and physical therapy .
It's true that finding out that your child's head is abnormally shaped is not a happy experience. It's normal to have thoughts like, "Will my child have to have surgery? What will his future be like?" Even though surgery is a possibility, the results are usually good. It helps the child's head and brain develop properly.
Your baby's first year may not be like other babies'. For example, he may have to go to the doctor more often, or he may need to wear a special helmet. But don't let that stop him from laughing and playing. If you have any questions or concerns about your baby's condition, talk to your doctor. They will be with you every step of the way to make sure your baby is healthy and developing as expected.
Final Take-Home Message
Okay, here are some of the most important things you need to remember from what we've talked about:
- Don't panic if you notice a change in the shape of the head, but keep an eye out: If your baby's head takes on an elongated, narrow shape, or if there is a bump on the top of the head, it could be a sign of scaphocephaly.
- Seek immediate medical attention: If in doubt, see your child's doctor for a checkup. Early diagnosis is very important.
- There are treatments: The main treatment for scaphocephaly is surgery. This makes room for the brain and corrects the shape of the head.
- Surgery is successful, but long-term monitoring is needed: Although surgery is usually successful, the child's development needs to be monitored closely. Additional therapy may be needed.
- You are not alone: Doctors, nurses, and other healthcare providers are ready to help you and your child at a time like this.
Remember, the most important thing is to give your baby love, care, and proper medical care.
