Examples are given of the Australian Cranio-Facial Unit's methods of dealing with facial disharmony and malocclusion by orthognathic surgery. Members of the Unit specialize in different aspects of craniofacial structure and function, and their teamwork is described. Treatment planning and assessment are illustrated by traditional cephalometric and other analytical procedures, and by pattern profile analysis. An appraisal is made of the Unit's increasing use of computer technology to facilitate these analyses, and to integrate various sources of information about facial disharmony.
