Background and objectives : The use of computer-assisted techniques in reconstruction of orbitozygomatic fractures has been the hot subject in the literature during the past 10 years. Such techniques are supposed to offer high degree of accuracy. However none of the published studies reported objective means to evaluate accuracy of reconstruction.

Methods : Twelve patients with unilateral massively displaced or comminuted orbitozygomatic complex fractures received computer-assisted reconstruction guided by stereolithographic models and zygomatic templates. Titanium meshes and fixation plates were bent onto the models preoperatively, while the templates were used intraoperatively for guidance of zygomatic reduction into the pre-planned position. Linear and angular measurements were used to assess accuracy of reconstruction on the postoperative 3D-CT images.

Results : Results are currently being generated and will be presented and disussed during the conference.
