Abstract:

Objective

To investigate the surgical method of simple unilateral zygomatic fracture which can keep facial bisymmetry and excellent stability of reduction and fixation.

Methods

17 cases with zygomatic fracture were included in this study. The patients were given maxillary vestibular sulcus incison and zygomatic temporal bone head traction fixation. Clinical examinations were followed up at 1 month， 3 months， 6 months and 1 year. CT test and cephalometric analysis X-ray measurement were taken at 3 months after surgery to achieve the height of the bilateral exterior orbital rim， the width of the bilateral inferior orbital rim and the length of the bilateral zygomatic arch. Then datas was analyzed with t test.

Results

The soft tissue of all 17 cases healed primarily. No obvious recurrence such as displacement or deformation of the zygoma was found one year post operation. CT and cephalometric analysis taken at 3 months showed that the zygoma healed well on fracture line and the t test showed no statistical difference （P＞0.05）.

Conclusions

This improved surgical approach and fixation method for simple unilateral zygomatic fracture is a satisfied surgical method with no facial scars， excellent stability of reduction and fixation， and good function， which is potential for further application.
