title: Mirroring Tool: The Simplest Computer-Aided Simulation Technology?
abstract: OBJECTIVE
  The aims of this study were to present our experience in the use of the mirroring tool in computer-aided simulation (CAS) as well as to describe its diversified uses and indications systematically.
  
  
  METHODS
  Between 2006 and 2012, 144 patients underwent preoperative CAS with mirroring tool developed by our department called Accu-Navi System. Various mirroring methods were performed and classified systemically. The outcome was evaluated thru its performance intraoperatively and the results postoperatively.
  
  
  RESULTS
  The optimal preoperative plans were achieved for all 144 patients using the mirroring tool. This provided the surgeon with accurate surgical information preoperatively and intraoperatively. There were 138 operations performed based on the preoperative plan. The duration of the operations was significantly shortened with improved surgical accuracy and safety. The mean discrepancy was confirmed to be less than 1.0 mm by comparing postoperative computed tomography with the preoperative plan. Postoperative esthetics improved remarkably along with patients' satisfaction without complications thru long-term follow-up evaluations.
  
  
  CONCLUSIONS
  The mirroring tool with its many uses can be a valuable CAS procedure for craniofacial surgery.
