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.
眼眶骨折的最有效治疗方法仍存在争议,文献中提出了不同的治疗策略。所有这些策略都集中在眼眶结构的重建上,而忽略了内侧壁和下壁的主要功能,这些壁在高能创伤时会断裂。作者的目的是在眼眶骨折修复中强调不同重建技术之间的差异,倾向于赞成修复而不是重建眼眶底部,假设可能会发生第二次创伤,并且留在眼眶中的重建材料可能会在这种情况下损坏视觉器官。基于此主题,作者提出了一种使用定制的立体光刻模型和聚乳酸网制成的可吸收板进行重建的策略,该网单独使用或与骨移植物联合使用,以获得更好的修复效果。目前,这种方法最适合运动员和年轻人。即使对该方法进行更深入的评估将是有益的,但所提出的一系列病例研究也可能为未来的讨论提供启发。
