Skull molding caps: an adjunct to craniosynostosis surgery.

External cranial vault molding using dynamic splinting is an adjunct to surgery in the treatment of craniosynostosis skull deformities. The skull molding cap not only maintains desired skull form, but also provides further active molding to normalize skull shape. Dynamic skull remodeling from these devices occurs primarily by translational movements of bone. Traction and compression result in bony repositioning which allows further reshaping as the osteoblasts and osteoclasts respond to these stresses. Three basic designs have been described. In practice, each one must be modified to meet individual needs, and adaptations are made according to established principles of dynamic splinting.
