Multidisciplinary Treatment of Antley-Bixler Syndrome

Abstract

Antley-Bixler syndrome is a rare form of craniosynostosis characterized by unique clinical features that present particular challenges to long-term treatment. Typical craniofacial features include midface hypoplasia, trapezoidocephaly, frontal bossing, ocular proptosis, low-set protrusive ears, and choanal atresia. A staged surgical approach including fronto-orbital and midface advancements is required for intracranial pressure reduction, globe protection, airway patency, and malocclusion. In this case report, the combined, longitudinal surgical and orthodontic treatment strategies employed to correct severe facial deformity in a long-term 21-year survivor of Antley-Bixler syndrome are reviewed.
