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.
What causes the fontanelle to close early?
SMALL FONTANEL OR EARLY FONTANEL CLOSURE
Craniosynostosis is the premature closing of one or more cranial sutures, resulting in an abnormal head shape. The condition can be idiopathic or caused by hyperthyroidism, hypophosphatasia, rickets, or hyperparathyroidism.
Is craniosynostosis serious?
Craniosynostosis can occur by itself or as a part of certain craniofacial (head and facial) syndromes. If left untreated, craniosynostosis can lead to serious complications, including: Head deformity, possibly severe and permanent. Increased pressure on the brain.
How do I know if my baby has craniosynostosis?
What are the symptoms of craniosynostosis?
- Full or bulging fontanelle (soft spot located on the top of the head)
- Sleepiness (or less alert than usual)
- Scalp veins may be very noticeable.
- Increased irritability.
- High-pitched cry.
- Poor feeding.
- Projectile vomiting.
- Increasing head circumference.
How do you fix craniosynostosis?
Treatment. A small number of babies with mild craniosynostosis won’t need surgical treatment. Rather, they can wear a special helmet to fix the shape of their skull as their brain grows. Most babies with this condition will need surgery to correct the shape of their head and relieve pressure on their brain.
How long does it take the Fontanel to close?
The posterior fontanelle usually closes by age 1 or 2 months. It may already be closed at birth. The anterior fontanelle usually closes sometime between 9 months and 18 months. The sutures and fontanelles are needed for the infant’s brain growth and development.
What happens if Fontanelle doesn’t close?
Soft spot that doesn’t close
If the soft spot stays big or doesn’t close after about a year, it is sometimes a sign of a genetic condition such as congenital hypothyroidism.
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 I know if I have craniosynostosis?
Doctors can identify craniosynostosis during a physical exam. A doctor will feel the baby’s head for hard edges along the sutures and unusual soft spots. The doctor also will look for any problems with the shape of the baby’s face.
Is craniosynostosis genetic?
Craniosynostosis occurs in one in about 2500 live births and affects males twice as often as females. It is most often sporadic (occurs by chance with no known genetic cause), but in some families, craniosynostosis is inherited by passing on specific genes that are known to cause this condition.
What happens if craniosynostosis is not treated?
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.
Why does my baby have a ridge on his forehead?
When a child has metopic synostosis: The metopic suture—the joint that runs from the baby’s fontanel (the “soft spot” at the top of the head) down the forehead to the top of her nose—closes too early. The baby develops a noticeable ridge extending along the center of her forehead. Her forehead will look overly narrow.
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.
Can craniosynostosis be fixed without surgery?
Because of the progressive nature of the cranial deformity, most children with craniosynostosis are recommended for surgery. However, children with mild deformities or those who present late without signs of increased intracranial pressure (ICP) are occasionally treated without surgery.
When is craniosynostosis detected?
Craniosynostosis is most often diagnosed after birth when the infant’s head shape is abnormal; however, it can occasionally be detected prenatally through ultrasound.
Can craniosynostosis be prevented?
Can Craniosynostosis be prevented? Genetic counseling is recommended to detect chromosomal and genetic forms of Craniosynostosis. Nothing is known to prevent isolated cases of the disorder. Pre-natal exposure to cigarette smoking should be avoided.
