Objective: To evaluate the effect of computer assisted navigation system in the treatment of unilateral zygomatic complex fractures.

Methods: Five patients with unilateral zygomatic complex fractures were included in this study.Preoperative design, intraoperative real-time navigation and postoperative evaluation with chromatogram were executed in the unaffected and affected side.

Results: Using computer assisted navigation system, the position and direction of the affected side of the unilateral zygomatic complex fracture were confirmed and shown real-time on the screen. The global maximal deviation was less than 2 mm between the affected side and the mirror side of the healthy side with chromatogram.

Conclusions: Computer assisted navigation system can instruct the treatment of unilateral zygomatic complex fractures effectively. The global comparison with chromatogram is more objective for the unilateral zygomatic complex fractures.
