title: Alloplastic augmentation of the mandibular angle.
abstract: OBJECTIVE
  This article describes the use of a large-pore polyethylene implant for mandibular angle augmentation.
  
  
  METHODS
  Patients with severe facial deformities who had previously undergone multiple surgical procedures and were now seeking esthetic improvement were included in this series. Their deficient mandibular angles and reduced ramus height were corrected with polyethylene implants appropriately sculptured and fixed to the mandible through extraoral incisions that preexisted in most patients. The surgical technique is described, and four representative cases are presented that illustrate the changes in facial contour and esthetics.
  
  
  RESULTS
  Postoperative appearance was considered very satisfactory, and the patients' esthetic expectations were met to a great extent. The mandibular angle was well outlined, and facial contour and proportions were enhanced.
  
  
  CONCLUSIONS
  This surgical procedure is recommended for mandibular angle augmentation when proper indications are strictly observed and surgical steps are accurately followed.
