Frequent question: What causes a baby’s skull to fuse too early?

Craniosynostosis is a birth defect in which the bones in a baby’s skull join together too early. This happens before the baby’s brain is fully formed. As the baby’s brain grows, the skull can become more misshapen. The spaces between a typical baby’s skull bones are filled with flexible material and called sutures.

How do I know if my baby has craniosynostosis?

What are the symptoms of craniosynostosis?

  1. Full or bulging fontanelle (soft spot located on the top of the head)
  2. Sleepiness (or less alert than usual)
  3. Scalp veins may be very noticeable.
  4. Increased irritability.
  5. High-pitched cry.
  6. Poor feeding.
  7. Projectile vomiting.
  8. Increasing head circumference.

Can craniosynostosis be fixed?

The main treatment for craniosynostosis is surgery, usually within the first year of life. Surgery can help the skull to develop normally and allow space for the brain to develop. Without surgery, the shape may become more unusual, and this can lead to complications.

How common is craniosynostosis?

Craniosynostosis is common and occurs in one out of 2,200 live births. The condition affects males slightly more often than females. Craniosynostosis is most often sporadic (occurs by chance) but can be inherited in some families.

What causes a baby’s head to grow too fast?

It’s normal for a baby’s head to grow a lot during the first year. But with congenital hydrocephalus, the head may grow faster than the normal rate for a baby’s height and weight. The condition may cause the soft spot (fontanelle) on your baby’s head to feel firm or bulge out.

How long does it take for a baby’s skull to fuse?

When babies are born their skulls are soft, which helps them pass through the birth canal. It can take 9-18 months before a baby’s skull is fully formed. During this time some babies develop positional plagiocephaly. This means that there is a flat area on the back or side of the head.

What happens if craniosynostosis is not treated?

Craniosynostosis Symptoms and Effects

If not corrected, craniosynostosis can create pressure inside the skull (intracranial pressure). That pressure can lead to development problems, or to permanent brain damage. If not treated, most forms of craniosynostosis can have very serious results, including death.

Can craniosynostosis cause speech delay?

The two problems that can be associated with sagittal craniosynostosis are speech and language delay and raised intracranial pressure. Some children with sagittal craniosynostosis tend to start to speak later than other children but with help from a speech and language therapist they usually catch up.

How do you fix craniosynostosis?

One treatment method your doctor may recommend is traditional open surgery, referred to as cranial vault remodeling.

Will Ridge on baby’s forehead go away?

When the metopic suture fuses, the bone next to the suture will often thicken, creating a metopic ridge. The ridge may be subtle or obvious, but it is normal and usually goes away after a few years.

Causes of craniosynostosis

About 1 out of every 2,500 babies is born with this condition. In most, the condition happens by chance. But in a smaller number of affected babies, the skull fuses too early due to genetic syndromes.

What does a baby with hydrocephalus look like?

What is a big head a sign of?

Macrocephaly refers to an overly large head. It’s often a symptom of complications or conditions in the brain.
