title: [The use of Piezosurgery osteotomy in treatment of long-standing maxillary fractures: report of 12 consecutive patients].
abstract: OBJECTIVE
  To evaluate the clinical applicability of Piezosurgery osteotomy: a new safe technique in managing long standing maxillary fractures.
  
  
  METHODS
  12 patients with long-standing maxillary fractures were surgically treated using Le Fort I osteotomy. During operation, Piezosurgery osteotomy was used for bone cutting and splitting. After repositioning, the bone segments were rigidly fixed with micro Ti-plate, Ti-mesh. All the patients were followed up for 6 to 12 months, and the functional and esthetic results were evaluated.
  
  
  RESULTS
  Ultrasonic microvibrations allow accurate bone cutting without oscillating injuries to the soft tissue. All the wounds healed primarily without complications. The postoperative occlusion and appearance were satisfactory.
  
  
  CONCLUSIONS
  Maximal recovery of mastication and appearance can be achieved by using Piezosurgery osteotomy with fixation materials such as Ti-plates and Ti-meshes in selected patients with long-standing maxillary fractures.
