Critical Degree of Orbital Floor Displacement Drives Operative Repair of Zygomatic Maxillary Complex (ZMC) Fractures: Findings from a 10-year retrospective study.

In this cohort, patients more likely to undergo surgical reduction were young patients with ophthalmologic symptoms on presentation and at least 4mm displacement of the orbital floor. Low kinetic energy ZMC fractures may warrant surgical management as often as high energy ZMC fractures. While orbital floor comminution has been shown to be a predictor for operative reduction, in this study we also demonstrated a difference in rate of reduction based upon severity of orbital floor displacement. This may have significant implications in both the triage and selection of patients most suitable for operative repair.
