[Application of computer assisted navigation in the treatment of unilateral zygomatic complex fractures].
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.
