Epidemiology
It is estimated that craniosynostosis affects 1 in 2,000 to 2,500 live births worldwide. Sagittal synostosis is the most common phenotype, representing 40 to 55% of nonsyndromic cases. The second most common type is the coronal synostosis representing 20 to 25%. The metopic synostosis comes third with 5 to 15% and the lambdoid synostosis is only seen in 0 to 5% of nonsyndromic cases.
In about 5 to 15% more than one suture is affected, which referred to as complex craniosynostosis. This is generally part of a syndrome.
