Mirror imaging and preshaped titanium plates in the treatment of unilateral malar and zygomatic arch fractures.

Abstract

OBJECTIVE

The aim of this study is to discuss the application of mirror imaging and preshaped titanium plates in the treatment of unilateral malar and zygomatic arch fractures.

STUDY DESIGN

Four patients with unilateral malar and zygomatic arch fractures were included in this study. All patients underwent preoperative CT scan. CT data were processed with Surgicase. Two 3D skull models were reconstructed using a rapid prototyping device. The first model was the original model obtained from CT scanning; the other model was obtained by mirroring the unaffected side onto the fractured side. Simulation surgery was performed on the first model. For the second model, titanium plates were shaped in advance and a resinous guide plate was created to guide surgical reduction. When using the resinous guide plates, 4 patients' fractures were reduced and fixed with preshaped titanium plates. The pre- and postoperative displacement of zygomatic markers were analyzed in Surgicase.

RESULTS

According to the measurement of fracture displacements, the facial asymmetry of all 4 patients was greatly improved at the 1-month follow-up.

CONCLUSIONS

Mirror imaging and preshaped titanium plates are viable choices for the treatment of unilateral malar and zygomatic arch fractures. Combined use of these techniques can improve facial symmetry.
