A Case Report: Nager Acrofacial Dysostosis [PDF]

open access: yesIranian Journal of Otorhinolaryngology, 2012
Introduction: Nager syndrome is a malformation resulting from problems in the development of the first and second branchial arches and limb buds. The cause of the abnormal development of the pharyngeal arches in Nager syndrome is unknown.
