The purpose of this study was to document changes in social perceptions and facial esthetics, and document occlusion outcomes in a series of short face (SF) dentofacial deformity (DFD) subjects. The investigators hypothesized that subjects would achieve positive change in social perceptions and facial esthetics, and maintain a long-term corrected occlusion after undergoing bimaxillary and chin osteotomies.A retrospective cohort study was implemented. Photographic records and occlusion parameters were studied preoperatively and >2 years after surgery. The first outcome variable was social perceptions of SF subjects, judged by laypersons. The second outcome variable was facial esthetics, judged by professionals. The third outcome variable was occlusion maintained long-term.Fifteen subjects met inclusion criteria. Mean age at operation was 33 years. Consistent facial contour deformities at presentation included deficient maxillary dental show and downturned oral commissures. As a group, there was improvement (P < 0.05) in 11 of 12 social perceptions, judged by laypersons, all subjects achieved correction of the facial esthetic parameters studied by professionals, and all subjects maintained a favorable occlusion long-term.In SF DFD subjects, bimaxillary and chin surgery proved effective to improve social perceptions, to correct facial contour deformities, and in achieving a long-term corrected occlusion.
