ABSTRACT
Apert syndrome is well known condition with craniosynostosis, midface hypoplasia, exorbitism, and typical symmetric syndactyly of hands and feet. Surgical correction method should be selected according to the type and the severity of the deformity and the patient's age. We have experienced an adult atypical Apert syndrome patient who has brachycephaly and midface hypoplasia, without exorbitism, and has limb deformities such as brachymetatarsia and ectrodactyly without syndactyly of hands and feet, which are not typical in Apert syndrome patients. For the simultaneous correction of the cranial vault and the facial deformities, we combined Le Fort II advancement osteotomy and advancement genioplasty as well as transposition cranioplasty at the same time, and obtained successful result. Through our limited experience, we concluded our modified combined methods could be safely applied to the adult patients with various types of craniofacial deformity.
