51 patients with orbital floor fractures were studied retrospectively to evaluate results in relation to time of surgical repair and fracture size. Early repair (less than 2 months) gave better results than late repair (greater than 2 months) in regard to both enophthalmos and extraocular muscle dysfunction. Large fractures (greater than one-half floor or greater than or equal to 15 fracture volume units) were most likely to be associated with significant enophthalmos after surgery. We recommend tomography when necessary to estimate fracture size, and advise early repair of large fractures, preferably within two weeks after injury. Patients with significant extraocular muscle dysfunction due to tissue entrapment, regardless of fracture size, should be repaired early, preferably within 2 weeks after injury, if improvement does not occur spontaneously by that time.
对51例眶底骨折患者进行回顾性研究，以评估手术修复时间和骨折大小与治疗结果的关系。就眼球内陷和眼外肌功能障碍而言，早期修复（小于2个月）比晚期修复（大于2个月）效果更好。大型骨折（大于眶底一半或大于或等于15个骨折体积单位）术后最有可能出现明显的眼球内陷。我们建议在必要时进行断层扫描以估计骨折大小，并建议对大型骨折进行早期修复，最好在受伤后两周内进行。因组织嵌顿导致明显眼外肌功能障碍的患者，无论骨折大小，如果届时未自发改善，均应尽早修复，最好在受伤后2周内进行。
