This study retrospectively examines 551 patients with 597 orbital floor fractures for sequelae of enophthalmos and diplopia. Ocular injuries are associated with 6.9% of the fractures. Nondisplaced orbital floor fractures have been treated with observation alone, resulting in an incidence of sequelae of zero in 263 patients. Displaced fractures that had not undergone surgery have resulted in an incidence of sequelae of 18 (34%) in 53 patients. Displaced fractures that had undergone orbital floor exploration have resulted in an incidence of sequelae of 29 (10.3%) in 281 patients. Only one mild loss of visual acuity has complicated the 281 surgical procedures. It is concluded that orbital floor exploration is not indicated in patients with nondisplaced fractures of the orbital floor and that orbital floor exploration is a safe and effective means of reducing the complications associated with displaced fractures of the orbital floor.
本研究回顾性检查了551例患有597处眶底骨折的患者，以了解眼球内陷和复视的后遗症情况。眼部损伤与6.9%的骨折相关。非移位性眶底骨折仅采用观察治疗，263例患者的后遗症发生率为零。未接受手术的移位性骨折在53例患者中的后遗症发生率为18例（34%）。接受眶底探查的移位性骨折在281例患者中的后遗症发生率为29例（10.3%）。在这281例手术中，仅出现1例轻度视力丧失。结论是，眶底非移位性骨折患者无需进行眶底探查，而眶底探查是减少与眶底移位性骨折相关并发症的一种安全有效的方法。
