Craniosynostosis (say "kray-nee-oh-sih-noh-STOH-sus") is a problem with the skull that causes a baby's head to be oddly shaped. In rare cases it causes pressure on the baby's brain, which can cause damage. It is also called craniostenosis.
A baby's skull is not just one bowl-shaped piece of bone. It is made up of five thin, bony plates that are held together by fibrous material called sutures. The sutures let the skull expand as the brain grows. Over time, the sutures harden and close the skull bones together.
When a baby has craniosynostosis, one or more of these sutures close too soon. How the problem affects your baby depends in part on how many of the sutures close too soon:
Experts aren't sure what causes this problem. In some cases, it runs in families. If you've had a baby with craniosynostosis and are planning another pregnancy, you may want to talk to your doctor about genetic counseling.
The most common sign is an oddly shaped head at birth or by the time the child is a few months old. For example, the skull may become long and narrow. Or it may be very flat and broad in front or back or on the sides. The baby may have a misshapen nose or jaw.
An oddly shaped head may be the only sign of craniosynostosis.
In rare cases, the disease causes pressure to build up on the baby's brain. This can cause brain damage and can make the baby develop more slowly than other children. If you know that your baby has this condition, call your doctor right away if your baby:
You or your doctor may notice that your baby has an odd-shaped head at birth, shortly after birth, or later at a well-child checkup.
Just because your baby has an oddly shaped head doesn't mean that he or she has craniosynostosis. Head shape may be affected by how your baby was positioned in your uterus, the birth process, or your baby's sleep position. Talk to your doctor if you are concerned about the shape of your baby's head.
Your doctor will:
Your baby's doctor may also order a skull X-ray or CT scan.
Surgery is the usual treatment to correct craniosynostosis. It's usually done in the first year of life. The earlier your child has surgery, the better the results.
The surgeon removes strips of bone in the skull to create artificial sutures. This surgery prevents or relieves pressure on the brain and allows the skull to expand normally. It also corrects the shape of your baby's head. Your child may wear a special helmet or other device after surgery.
If there is pressure on the brain, your child needs surgery right away. If your baby doesn't seem to have pressure on the brain, your doctor may advise you to wait and see if the head shape returns to normal without surgery. But your child may still need surgery later.
If your child needs surgery, talk with your doctor about what to expect. It may help to see some before-and-after pictures of other children who have had the same type of surgery so that you are prepared for how your child will look right after the surgery. There may be a lot of swelling and bruising at first.
Being involved in your baby's care while he or she is in the hospital may help you feel more comfortable when you take your baby home. You'll need to know how to care for your baby's incision and what problems to watch for. Problems after surgery aren't common.
It's normal to feel a wide range of emotions when your child has a problem like craniosynostosis. Counseling or a support group can help.
