The cranial vault is not a single bone. It is made up of a number of separate bones, which come together at the cranial sutures. In craniosynostosis, these sutures are prematurely fused. This causes a restriction in growth of the skull, leading to characteristic head shape abnormalities.
Most cases of craniosynostosis involve only a single suture and no specific cause is found. In a number of cases, a genetic cause can be found and in some cases, the craniosynostosis is associated with a syndrome.
Single suture craniosynostosis
- Apert syndrome
- Crouzon syndrome
- Pfeiffer syndrome
- Muenke syndrome
- Saethre Chotzen syndrome
The Australian Craniofacial Unit manages these conditions in a coordinated, multidisciplinary, patient-centred way, based on established protocols to ensure consistent best practice.
