title: Genioplasty and chin augmentation with Medpore implants: a report of 650 cases.
abstract: BACKGROUND
  Genioplasty is an old and useful technique. Chin augmentation with Medpore has become popular in recent years. The authors briefly examine their experience with the two techniques.
  
  
  METHODS
  From 2000 to date, 500 genioplasties and 150 chin augmentations with Medpore have been performed. The versatility and benefits of the two techniques are discussed.
  
  
  RESULTS
  Most of the patients achieved satisfactory results with few complications. Genioplasty is recommended for severe developmental or complicated retrogenia and for deviated chin. Both techniques can be used for mild to modest retrogenia. Medpore is especially useful for patients who need a meticulous revision of the chin shape or contour.
  
  
  CONCLUSIONS
  Chin shape and contour are as important as the chin position. Although genioplasty has the widest range of indications, chin augmentation with Medpore has the advantage of minimal risk for some patients who need to change the chin shape or contour. Medpore is totally different from other alloplastic chin implants such as silicone.
