Abstract：
Orbital floor fractures (OFFs) are common injuries of the midface and may result in long-term complications. The aim of this study was to compare two restoration materials, PDS foils and titanium meshes, with regards to (1) clinical outcome and (2) reduction in orbital volume. The monocentric discovery cohort was analyzed retrospectively and included 476 patients with OFFs treated between 2010 and 2020. A subcohort of 104 patients (study cohort) with isolated OFFs and available high-resolution imaging material was used for volume measurements. Postoperative complications were not significantly different between patients treated with different restoration materials. Prevalence of revision surgery was significantly higher in patients treated with thick PDS foils (25 mm). OFFs treated with PDS foils and titanium meshes showed a significant reduction in orbital volume (p = 0.0422 and p = 0.0056, respectively), however, this volume decrease was significantly less pronounced in patients treated with PDS foils alone (p = 0.0134). Restoration using PDS foil in an isolated OFF reduces the orbital volume to a lesser extent than titanium mesh. Class III patients according to the classification of Jaquiéry with a missing bony ledge medial to the infraorbital fissure particularly benefit from restoration with PDS foils due to a lower reduction in the orbital volume. Regarding short- and long-term postoperative complications, a PDS foil thickness of 0.15 mm appears equivalent to titanium mesh in the treatment of OFFs.
摘要：
眶底骨折（OFFs）是中面的常见损伤，可能导致长期并发症。这项研究的目的是比较两种修复材料，PDS箔和钛网，关于（1）临床结果和（2）眼眶体积减少。回顾性分析单中心发现队列，包括2010年至2020年接受OFFs治疗的476例患者。使用具有分离的OFF和可用的高分辨率成像材料的104名患者的子队列（研究队列）进行体积测量。不同修复材料治疗的患者术后并发症无明显差异。在使用厚PDS箔（25mm）治疗的患者中，翻修手术的患病率明显更高。用PDS箔和钛网处理的OFF显示轨道体积显着减少（分别为p=0.0422和p=0.0056），然而,在单独使用PDS箔片治疗的患者中,这种体积减少明显不那么明显(p=0.0134).在隔离的OFF中使用PDS箔的恢复使轨道体积的减小程度小于钛网。根据Jaquiéry的分类，第三类患者在眶下裂隙内侧缺少骨壁，特别是由于眼眶体积减少较少，因此可以从PDS箔的修复中受益。关于术后短期和长期并发症，在OFF的处理中,0.15mm的PDS箔厚度看起来相当于钛网。
