Is coronal suture synostosis?
In newborns, the bones of the skull are separated by small spaces or growth plates called sutures. One seam runs over the top of the skull from ear-to-ear. This coronal suture may close (fuse) prematurely on one side (unicoronal) or both sides (bicoronal). When this happens, it is called coronal synostosis.
How common is coronal craniosynostosis?
Craniosynostosis is common and occurs in one out of 2,200 live births. The condition affects males slightly more often than females.
At what age does the coronal suture close?
24 years
The average age of coronal suture closure is 24 years; however, numerous diseases and factors may cause the dysfunction of a suture. The most common dysfunction is early closure or abnormal closure of a suture or group of sutures of the skull. Premature ossification of the sutures is referred to as craniosynostosis.
What is unilateral coronal craniosynostosis?
Unilateral (one side) coronal craniosynostosis causes a rotated appearance to the face with flattening of the forehead and elevation of the eye socket roof on the affected side along with rotation of the nose. Sometimes the anterior fontanel is somewhat displaced to the opposite side.
Can you feel coronal suture?
When both coronal sutures are affected, a ridge can be felt on both sides of the head running from the top of the skull down the sides in front of the ears.
How do you rule out craniosynostosis?
Imaging studies. A computerized tomography (CT) scan or magnetic resonance imaging (MRI) of your baby’s skull can show whether any sutures have fused. Cranial ultrasound imaging may be used. Fused sutures can be identified by their absence — because they’re invisible once fused — or by a ridging of the suture line.
Can you feel the coronal suture?
How do I know if my baby has 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.
