小儿眶底骨折临床分析

Clinical analysis of orbital floor fractures in children

目的 :探讨小儿眶底骨折的临床特点及治疗。方法 :回顾性研究 6 7例年龄小于 18岁的单纯眶底骨折患者 ,采用手术治疗眶底骨折 ,植入物为硅胶或羟基磷灰石。结果 :体育运动 (37 3% )和暴力伤 (2 3 9% )是造成小儿眶底骨折的主要原因 ;79 1%的病人有眼球运动疼痛和 /或恶心呕吐 ,复视 (79 7% ) ,严重的眼球运动障碍 (6 1 2 % )和眼球内陷 (2 5 4% )。小儿眶底骨折主要是陷阱型 (trapdoortype)骨折 (5 6 8% ) ,可伴有下直肌嵌顿。早期手术 (<1个月 )比晚期手术 (>1个月 )可以更有效地改善患者症状 (P <0 0 5 )。结论

Objective:To investigate the clinical characteristics and management of orbital floor fractures in children.Methods:Deta of 67 patients younger than 18 years old with isolated orbital floor fracture were analysed retrospectively.The fracture was repaired with implant materials including silastic and hydroxyapatite sheet.Results:Sport injury (37.3%)and resort to violence(23.9%)were the main causes of orbital fracture.79.1% patients complained pain with eye movement and may or may not had nausea and vomi- ting,diplopia(79.7%),severe restriction of ocular motility(61.2%)and enophthalmos(25.4%).Most patients had a trapdoor type fracture(56.8%)with the inferior rectus entrapped.Early surgical intervention(<1 month) resulted in a more complete recovery than the late intervention group( P <0.05).Conclusion:Early surgical repair is an effective treatment for orbital floor fracture in children.
