摘要

Introduction

In maxillofacial trauma, isolated orbital floor fractures account for about 4–16% and this rate increases to about 30–55% when combined with zygomatic complex fractures. Treatment of orbital floor fractures is mainly aimed at re-establishing orbital floor support by lining graft materials. This study aimed to describe the clinical and paraclinical features of orbital floor fractures and to evaluate treatment outcomes of orbital floor reconstruction using outer cortex of mandibular angle.

Materials and Methods

A time-series clinical study consists of 16 patients were diagnosed with orbital floor fractures and admitted to the Department of Maxillofacial Surgery, … was conducted. The efficacy and safety of the surgical procedure were evaluated at 1 week, 3 months, and 6 months postoperatively.

Results

At the 6-month follow-up, significant improvements were observed in enophthalmos (87.5%), hypoglobus (93.8%), diplopia (56.3%), and ocular motility disturbance (81.3%). No severe complications, such as vision loss or graft rejection, were reported. Minor complications, including infraorbital nerve injury (6.3%), ectropion (6.3%), scarring (18.8%), wound infection (6.3%) showed improvement over the 6-month period.

Conclusion

Orbital floor reconstruction using outer cortex of mandibular angle demonstrates high treatment efficacy with minimal complications.
