Core Extirpation and Zygoma Reduction: A New Surgical Approach for Fibrous Dysplasia of Zygomaticomaxillary Region.

INTRODUCTION

In case of zygomaticomaxillary fibrous dysplasia (FD), surgical treatment is often required due to visual disturbance, exophthalmos, and also necessary for cosmetic reasons. However, it is not easy to determine the timing and method of operation. The objective of our study is to define a new surgical option, for the treatment of FD of zygomaticomaxillary area.

MATERIALS AND

METHODS

Five patients affected by FD of their zygomaticomaxillary area who underwent surgery with a core extirpation were included in this study. A retrospective chart review and pre- and post-operative analysis of computed tomography scan were performed.

RESULTS

All patients underwent core extirpation surgery and zygoma reduction was combined in 2 patients. All patients showed the cessation of the increase of external size postoperatively and results of the operation were well maintained over the follow-up period of 1 year.

CONCLUSIONS

In this article, we present our experiences in the management of FD using the core extirpation with or without zygoma reduction, focusing on surgical indication, techniques, and results. Although there are limitations due to selective operative indication, the procedure can be usefully performed to prevent external growth and avoid repetitive surgery.
