Factors associated with diplopia before and after orbital blowout fracture reconstruction

Abstract

Background/Aims To ascertain factors associated with persistent diplopia after orbital fracture reconstruction. Methods In this retrospective study, we reviewed 798 cases with depressed fragment fracture at the Department of Kyoto Prefectural University of Medicine Hospital between January 2009 and November 2023. The restriction of extraocular movements and diplopia was assessed using the Hess area ratio (HAR). The factors for HAR% ≥85% before surgery and 6 months after surgery were assessed. Results Of the 798 cases in this study, 437 cases (54.8%) had an HAR% of ≥85%, and 361 cases (45.2%) had an HAR% of <85% before surgery. Age ≤18 years old (p=0.017), orbital tissue herniation volume

眼眶爆裂性骨折重建前后复视的相关因素

背景/目的探讨眼眶骨折重建术后持续性复视的相关因素。方法回顾性分析京都府立医科大学附属医院2009年1月至2023年11月收治的798例凹陷性碎片骨折患者。采用赫斯面积比（Hess area ratio， HAR）评价眼外运动受限和复视情况。评估术前和术后6个月HAR%≥85%的因素。结果本组798例患者中，437例（54.8%）术前HAR%≥85%，361例（45.2%）术前HAR% <85%。年龄≤18岁（p=0.017），眶组织突出体积<中位数（p=0.001），无眼外肌偏曲（p<0.001）和内侧壁（vs内侧壁和眶底伴柱状骨折）；p<0.001)与术前HAR%≥85%相关。332例手术患者中，术后HAR%≥85% 272例（81.9%），术后HAR%<85% 60例（18.1%）。年龄≤18岁（p=0.011），男性（p=0.014），无眼外肌偏曲（p=0.002）、内侧壁(vs内侧壁、眶底伴支柱性骨折；p=0.002)与术后6个月HAR%≥85%相关。结论年轻、男性和无眼外肌偏曲的患者术后6个月患眼眼球运动较好（HAR%）。数据共享不适用，因为没有为本研究生成和/或分析数据集。无数据。
