[Physiology of craniofacial development].

This topic summarizes basic principles of the development and the postnatal growth of the craniofacial skeleton. The different stages involved in the progressive ossification of facial bones are exposed: the intramembranous ossification, the endochondral (intracartilagenous) ossification and the changes (remodelling and relocation) associated with periosteal and endosteal membranes.
