Medpor plus titanic mesh implant in the repair of orbital blowout fractures

目的探讨Medpor填充联合钛网在眼眶爆裂性骨折中疗效。方法分析眼眶爆裂性骨折20例，均采用手术切开复位，钛网修复，Medpor材料填充，观察所有患者术后眼球内陷、复视、眼球运动、视力等变化，随访时间9～18个月，平均14．5个月。结果随访期内没有出现Medpor和钛网脱出和排斥现象。所有患眼手术前后视力无下降。术后所有患者眼球内陷症状均得到矫止，双眼突出度基本一致，相差均〈2mm。各方向眼球运动基本到位。18例复视消失，治愈率为90％，1例复视改善但仍存在，1例复视无改善。结论Medpor联合钛网植入在眼眶爆裂性骨折整复中是一种安全有效的治疗方法。

Objective To study the efficacy of porous polyethylene （Medpor） plus titanic mesh sheets in the repair of orbital blowout fractures. Methods A total of 20 patients underwent open surgical reduction with the combined usage of Medpor and titanic mesh. And they were followed up for average period of 14. 5 months （range： 9-18）. Results There is no infection or extrusion of medpor and titanic mesh in follow-up periods. There was no instance of decreased visual acuity at post-operation. And all cases of enophthalmos were corrected. The post-operative protrusion degree of both eyes was almost identical at less than 2 ram. The movement of eye balls was satisfactory, in all directions. Diplopia disappeared in 18 cases with a cure rate of 90% , 1 ease improved and 1 case persisted. Conclusion Medpor plus titanic mesh implant is a safe and effective treatment in the repair of orbital blow out fractures.
