title: [The preoperative design for remodeling inferior one-third facial contour].
abstract: OBJECTIVE
  Facial contour remodeling is an important part of plastic surgery. Some skeletal abnormalities, such as mandible protrude, maxillary retrusion, induce the facial asymmetry (including arrowe direction or/and coronary direction), malocclusion, etc. These abnormalities are seen commonly in the lower one third of the face. Evaluation and preoperative design is very important for the treatment of these abnormalities. The purpose of this item is to summarize our experience in the preoperative design during the treatment.
  
  
  RESULTS
  Observation of the facial feature of the patient, cephalometric tracing, face-bow transfer and model reconstruction were necessary for the preoperative design. Three-dimensional direction was included in the bone movement for operation and soft tissue should be taken into account simultaneously. All the factors mentioned above were summarized, and outcomes were gathered.
  
  
  CONCLUSIONS
  Determination of facial midline was very important, especially for asymmetry patient. The bone was moved in three-dimensional direction. The same site of osteotectomy may produce different effects by different movements.
