Binder´s syndrome (Maxillonasal dysplasia) which has previously been known as congenital dish face, scaphoid face, and congenital flat nose syndrome is a skeletal malformation characterized by an extremely flat, retruded nose and class III malocclusion.
The etiology is discussed in relation to birth trauma, nasal trauma in childhood, underdevelopment of premaxilla and an inhibition of ossification center in the canine region. The treatment of this syndrome usually require correction of 3 defects; (1) the perialar flatness (due to underdevelopment of the piriform margin); (2) the hypoplastic nose, which is flat and short, and has a small columella; (3) the short maxilla, with its malocclusion. In this paper we present two binder´s syndrome with extremely flat and retruded nose, which were corrected by Le Fort II osteotomy, calvarial bone graft and iliac bone graft, respectively. So we obtained satistactory results and report these with review of articles.
