title: Three-dimensional virtual technology in reconstruction of mandibular defect including condyle using double-barrel vascularized fibula flap.
abstract: OBJECTIVE
  The aim of this study is to demonstrate the reconstruction of mandibular defects including the condyle using a double-barrel vascularized fibula flap aided by three-dimensional virtual technology.
  
  
  METHODS
  Ten patients with the type H mandibular defects, who had undergone mandibular reconstruction using a double-barrel vascularized fibula flap, were reviewed for this study. Prior to the surgery, the patients CT scan data were analyzed virtually using SimPlant Pro™ software (version 11.04). The simulation allowed construction of an individual mandibular model serving to guide the clinical operation.
  
  
  RESULTS
  The preoperative virtual surgery greatly benefitted the actual surgery. The vertical height of the neomandible and facial contour were precisely predicted. Some minor complications were encountered. Postoperative three-dimensional reconstruction revealed a close match with the simulated condyle.
  
  
  CONCLUSIONS
  A double-barrel vascularized fibula flap can provide sufficient bone, both in length and vertical height, for the reconstruction of a type H mandibular condylar defect. Combined virtual three-dimensional reconstruction and rapid prototyping can improve postoperative outcomes in mandibular reconstruction.
