Profiloplasty of the lower face by maxillary and mandibular anterior segmental osteotomies


Maxillary and mandibular anterior segmental osteotomies (ASO) are ways to correct disharmony in the lip (contour, lip seal, and profile) and occasional dentoalveolar malocclusion. We performed 23 maxillary setback ASO, three maxillary advancement ASO, 21 mandibular setback ASO, and six mandibular advancement ASO in 28 patients to improve their lower facial profile. Other combined operative procedures include nine LeFort 1 osteotomies, four bilateral mandibular ramus osteotomies, two genioplasties, four mandibular angle contouring procedures, two reduction malar plasties, two piriform augmentations with bone graft, and a facelift for correcting of long faces, asymmetric faces, severe malocclusions, microgenias, prominent mandibular angles, prominent malar eminences, piriform recessions, and an aging face. Twenty five patients were satisfied with the results. Two patients complained of an over-recessed lip region, and one of septal deviation. There were no other significant complications or relapses throughout the followup period (9–30 months). Maxillary and mandibular ASO are effective, selective, relatively safe, and simple methods for correcting lower facial profile disharmony to attain a satisfactory aesthetic facial contour.
