In multisuture craniosynostosis, two or more cranial sutures have close too early. This is usually also the case in syndromic craniosynostosis, although unicoronal synostosis or other single suture involvement can incidentally occur. Craniosynostosis is referred to as syndromic if other congenital disorders are present. This often are congenital disorders of the face, hands and feet, but may also involve other organs, for instance heart disorders or anorectal anomalies.
