Orofacial deformities requiring genioplasty associated with orthognathic surgery in both jaws

The aim of this study is to evaluate the relationship between hard tissue surgery and the effect which it has on the overlying soft tissue. This predicts final facial proportions and profile, and determines the amount of genioplasty movement needed in all 3 dimensions for optimal chin esthetics. In the sample studied, were performed Le Fort I and bilateral sagittal split ramus osteotomies, and osteotomies of the inferior border of the mandible for sagittal augmentation and reduction, vertical augmentation and reduction, transverse correction of the chin. These surgical procedures enhanced the middle and lower third facial balances, both frontally and in profile, normalized the lower third of the face’s vertical and sagittal esthetic relationships, and softened the face. Sliding set back, asymmetric, and grafted genioplasties are less predictable than advancement genioplasty. Genioplasty is a useful versatile adjunctive surgical procedure to reach esthetical and functional results with the goal of overall facial harmony and balance.
