Malocclusion
ReplyDeleteThis is Apert syndrome, a syndromic craniosynostosis (premature fusion or growth arrest at one of the cranial sutures) from a mutation in fibroblast growth factor receptor 2. Note the bicoronal synostosis and maxillary hypoplasia giving a flat, recessed forehead and flat midface. Patients also have exorbitism, hypertelorism, a laterally down-sloping slant, low-set ears, and abnormally small, flat nasal structure. Oral exam shows a high arched palate and class 3 malocclusion.
