Quantitative evaluation of facial hypoplasia and airway obstruction in infants with syndromic craniosynostosis: relationship with skull base and splanchnocranium sutural pattern.

The skull base synostotic process drives the changes in facial complex growth and airway obstruction. Premature closure of synchondroses/sutures in the posterior branch of the coronal ring causes insufficient facial growth, maxillary retrusion, and more severe airway reduction.
