Medpor Titan外科种植体在眼眶爆裂性骨折修复术中的应用

目的评价镶嵌钛网高密度多孔聚乙烯（Medpor Titan）外科种植体在眼眶爆裂性骨折修复术中的作用。方法回顾性分析采用Medpor Titan修复眼眶爆裂性骨折的患者11例（11只眼）。术前存在眼球内陷、眼球运动障碍及复视,眼眶CT证实为眼眶爆裂性骨折。术后观察眼球突出度、眼球运动及复视等变化,并复查眼眶CT。结果术前9例合并眼球内陷有8例完全矫正,1例欠矫3 mm。术后眼球内陷1~3 mm,平均（-0.89±1.17）mm,与术前比较差异有统计学意义（P〈0.01）;术前10例眼球运动障碍的患者9例恢复正常,1例好转;合并复视的6例患者中5例复视消失,1例改善。复查眼眶CT见眶壁骨折复位良好,Medpor Titan无移位、脱出,无肌肉及软组织嵌顿。结论 Medpor Titan不仅能较好的用于眼眶骨折修复,且能在影像学上很好地显影,是较理想的眼眶骨折修复材料。

Clinical application of Medpor Titan surgical implants in orbital blowout fracture

Objective To evaluate the role of Medpor Titan surgical implants in repairing orbital Idowout fracture. Methods We reviewed history of 11 patients （ 11 eyes ）who received surgical reconstruction with Medpor Titan surgical implant for orbital blowout fracture. Patients presented with enophthalmos, diplopia and restriction of eye movement, and orbital blowout fracture was confirmed by orbital CT. Postoperative changes in eye movement, diplopia and enopbthalmos were observed, and patients were followed with orbital CT for structural changes. Results Significant enophthalmos was found preoperatively in 9 patients, and was completely conected in 8 of them. One patient had only 3 mm residual enoph- thalmos. The mean value was （ -0.89 ±1.17） mm （range 1 -3 ram）, and was significantly improved from that before treatment （ P 〈0.01 ）. Postoperative eye movement was satisfactory in 5 cases and improved in other cases. Diplopla pres- ented preoperatively in 6 patients. It disappeared in 5 of them, and improved in the other one. Orbital wall structure was restored well in all patients. There was no implant rejection, displacement, or soft tissue embed. Conclusion Medpor Ti- tan is an ideal material for the reconstruction of orbital blowout fracture for its favorable clinical outcomes and imaging friendly nature.
