Genioplasty

Abstract

Osseous genioplasty is a powerful tool in the armamentarium of the craniofacial surgeon. Whether performed in isolation in patients with class I occlusion, or combined with a sagittal split osteotomy in patients with malocclusion, genioplasty can dramatically affect facial proportions and harmony. Genioplasty refers to the surgical or nonsurgical manipulation of the chin form or the mandibular symphysis. Genioplasty may alter the morphology of the anterior mandible through augmentation, reduction, or asymmetric recontouring, using either autologous techniques (bony reconstruction or autologous fat grafting) or alloplastic techniques (silicone implant or collagen/hyaluronic acid fillers). This chapter focuses on autologous manipulation of the mandibular symphysis through osseous genioplasty and presents an overview of patient assessment, indications, and technique for osseous genioplasty.
