The surgical correction of maxillary hypoplasia and midfacial retrusion.

On the basis of 35 maxillary osteotomies of the Le Fort I and III types, the authors discuss the main problems connected with treatment of maxillary hypoplasia and midfacial retrusion. Special attention is paid to cases that demand coordinated treatment including skeletal as well as soft tissue repair and reconstruction. Thanks to combined treatment in all cases, including 7 patients with partial backward displacement of the osteotomized fragments whose occlusion could not be entirely corrected, striking or highly satisfactory improvement of appearance was achieved.
