title: Chin projection creation in patients with facial and cervical burn scar contracture.
abstract: BACKGROUND
  Loss of cervicomental angle is characteristic of severe facial and cervical burned patients due to scar contracture. This micrognathia-like deformity is also seen in patients following chin and neck reconstruction using skin expanded flaps. The aim of modern plastic surgery is to restore a harmonious and symmetrical facial appearance for burn survivors.
  
  
  METHODS
  Six facial and cervical burned patients with micrognathia-like deformity after neck reconstructions were reported. Chin augmentation with Medpor implant through submental approach was performed in 4 patients and intraoral access in 2 cases to restore their favorable chin projections. Five of them received cervicomental contour reconstruction simultaneously.
  
  
  RESULTS
  Patient follow-up ranged from 12 to 18 months. No implants became exposed nor infected. All patients had satisfactory results. We reviewed our experience with the use of the Medpor implant in burn chin reconstruction including preoperative and postoperative radiograph analysis.
  
  
  CONCLUSIONS
  With proper patient selection, pre-operative planning, and taking care of details during operation, augmentation genioplasty with Medpor implant offers a reliable, simple and satisfactory solution for improving micrognathia-like facial configurations in patients with scar contracture following severe burns.
