Craniofrontonasal dysplasia

Abstract

A series of 10 patients with craniofrontonasal dysplasia presenting to the Oxford Craniofacial Unit since 1983 is presented. In addition to the well-described combination of coronal synostosis and frontonasal dysplasia, 9 patients had very characteristic dry, curly or frizzy hair. All the patients were female. Recognition of the syndrome is important for genetic counselling, although the precise mode of genetic transmission is unclear with females predominating and males being less severely affected. Surgical correction was in two stages: early frontal advancement followed by correction of hypertelorism when the child became aware of the deformity. Four patients had their craniosynostosis treated in the Oxford Craniofacial Unit. Three patients had previously had frontal remodelling elsewhere. Nine patients had surgery for hypertelorism. The preferred technique for hypertelorism correction was facial bipartition. Following hypertelorism correction, the excess skin was allowed to redrape and subsequently dealt with by medial canthoplasties, thus avoiding a midline scar. Careful attention to the primary frontal advancement procedure is important to avoid complications following difficult dissection of the frontal bone flap at the time of hypertelorism correction.
