Orbital Floor Fractures Comparing Different Kinds of Reconstruction: A Proposal for Restoration of Physiological Anatomy.

Abstract

The most effective treatment for orbital fractures is still under debate and different strategies are proposed in the literature. All such strategies focus on reconstruction of the orbital structure, neglecting the main function of the medial and inferior walls, these latter being constructed so as to break during high energy trauma. The aim of the authors is to highlight the difference between different reconstructive techniques in an orbital fracture restoration, being inclined to favor repair over reconstruction of the orbital floor, assuming that a second trauma could happen and reconstructive material left in the orbit may damage the visual apparatus in such a scenario. Following this theme, the authors propose a reconstruction strategy using a custom made stereolithographic model and resorbable plate made of polylactic acid mesh molded onto it. The mesh is used alone or in combination with bone graft, to obtain a better reparative result. At present, this approach is best suited to sports people and the young. Even if a deeper evaluation of the method would be useful, the series of case studies presented could be of stimulus for future discussion.
