Craniomaxillofacial trauma“Mirroring” Computational Planning, Navigation Guidance System, and Intraoperative Mobile C-Arm Cone-Beam Computed Tomography With Flat-Panel Detector: A New Rationale in Primary and Secondary Treatment of Midfacial Fractures?
Section snippets
Patients and Methods
This study was approved by our institutional ethics committee, and the patients gave written informed consent. Five consecutive patients aged between 17 and 43 years with midfacial fractures were treated at the Hôpitaux Universitaires de Genève, Geneva, Switzerland, between October 2008 and September 2009 according to the following protocol: 1) preoperative mirroring computational planning, 2) bone repositioning by a navigation guidance system, and 3) intraoperative assessment of the adequacy
Results
This study included 5 patients, 1 with secondary left post–orbito-zygomatic fracture deformities (Fig 3), 1 with severely displaced NOE fractures, and 3 with severely displaced orbito-zygomatic fractures with loss of the classical anatomic landmarks (Fig 4). The patients were all male patients (1 Asian and 4 white), and their ages ranged from 17 to 43 years (mean age, 25 years). The intraoperative imaging process time (isocenter positioning, images acquisition and detection, 3D reconstruction)
Discussion
Functional and esthetic correction of deformities resulting from inadequate treatment of midfacial fractures continues to be one of the most difficult and challenging procedures for craniofacial surgeons.1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Popularized by Taylor et al,13 computer-assisted surgery (CAS) was initially based on the following inseparably linked steps: preoperative imaging, modeling, planning and simulation, registration, and action. The distinction of this system was its capability of

Mirroring enables more precise reduction and orbital floor restoration, because a discrepancy exceeding 2 mm is considered to be clinically relevant and requires immediate revisional surgery10,17. Concerning the combined use of intraoperative CBCT and navigation, the main indication is maxillofacial surgery for gunshot wounds.
