title: Augmentation genioplasty: when bone is not enough.
abstract: OBJECTIVE
  Augmentation genioplasty is indicated to correct microgenia. When a large defect must be corrected, the additional use of a soft alloplastic implant may be indicated.
  
  
  METHODS
  A 22-year-old patient is presented who required correction of microgenia. A 15-mm advancement of the chin was required to obtain an acceptable cosmetic result.
  
  
  RESULTS
  An augmentation genioplasty achieved an 8-mm correction. This was supplemented by a silicone gel-filled implant inserted subperiosteally. This resulted in an outstanding cosmetic result.
  
  
  CONCLUSIONS
  Chin contour is an important aspect of facial aesthetics. The sliding genioplasty is ideally suited for correcting most chin deformities; however, the insertion of an alloplast may augment patients with severe microgenia. Avoidance of the donor-site morbidity associated with the use of autogenous bone is a major benefit of this procedure.
