Early and late surgery in craniofacial dysostosis: a longitudinal cephalometric study.
Longitudinal clinical and cephalometric case studies are presented for two groups of patients with craniofacial dysostosis. The first sample includes two infants who underwent an extensive stripping procedure that was extended inferiorly to involve not only the coronal, but also the sphenozygomatic suture. The second sample includes two adolescents with midfacial hypoplasia who underwent a fronto-orbital-maxillary advancement. The extensive cranial stripping procedure had a favourable impact upon growth and development of the craniofacial structures, and longitudinal studies suggest the importance of promoting the growth potential of the bones contiguous to the affected sutures. Craniofacial surgery performed on adolescents results in a dramatic translocation of the skeletal and soft-tissue structures of the face. In contrast to early surgical intervention in infants in whom growth of the effected areas essential to the development of face and cranium was crucial, late surgery appeared to have little, if any, impact upon the development of the craniofacial skeletal structures that had been operated on.
