Gradual Bone Distraction in Craniosynostosis

Abstract

Seven patients with craniosynostosis (mean age 8 years, Apert syndrome, n = 4, Crouzon's disease, n = 3) underwent lengthening of the skull by gradual bone distraction. Three patients (group A) were treated by coronal craniectomy reaching the orbital fissure and gradual bone distraction. The other four (group B) underwent monobloc craniofacial disjunction and gradual bone distraction. The patients' progress was monitored clinically as well as by radiographs and photographs. The results showed that craniofacial disjunction followed by gradual bone distraction produced complete correction of exophthalmus and an improvement in the functional and aesthetic aspects of the middle third of the face without the need for bone grafts.
