The study was performed to evaluate the effectiveness and safety of porous polyethylene with embedded titanium in the repair of orbital blowout fracture. The study was designed as a prospective case series. Patients who were diagnosed with orbital blowout fracture from May 2012 to March 2013 were included in the study. A composite material of porous polyethylene and titanium mesh was used. Orbital volumes before and after surgery were measured, and the results of diplopia and ocular movement were recorded. The occurrence of diplopia was grouped and compared according to the time interval between injury and surgery. The incidence of other complications was also recorded. A total of 26 patients were involved in the study. The minimal follow-up time was 12 months. All surgeries were performed uneventfully. The orbital volume significantly decreased after the surgery, and the remission rate and the elimination rate of diplopia in 12 months were 85.7% and 47.6%, respectively. Postoperative diplopia was correlated with the time interval between injury and surgery. One patient presented with undercorrection of enophthalmos, and another patient presented with acute aggravation of diplopia and exophthalmos after surgery, which was resolved with treatment. In conclusion, porous polyethylene with embedded titanium was effective and safe in the repair of orbital blowout fracture, and studies with more subjects and longer follow-up period are recommended in future studies.
本研究旨在评估嵌入钛的多孔聚乙烯修复眼眶爆裂性骨折的有效性和安全性。本研究设计为前瞻性病例系列研究。2012年5月至2013年3月期间被诊断为眼眶爆裂性骨折的患者纳入本研究。使用了多孔聚乙烯和钛网的复合材料。测量手术前后的眼眶容积，并记录复视和眼球运动的结果。根据受伤与手术之间的时间间隔对复视的发生情况进行分组和比较。还记录了其他并发症的发生率。共有26例患者参与本研究。最短随访时间为12个月。所有手术均顺利进行。术后眼眶容积显著减小，12个月时复视的缓解率和消除率分别为85.7%和47.6%。术后复视与受伤和手术之间的时间间隔相关。1例患者出现眼球内陷矫正不足，另1例患者术后出现复视和眼球突出急性加重，经治疗后缓解。总之，嵌入钛的多孔聚乙烯修复眼眶爆裂性骨折有效且安全，建议未来研究纳入更多受试者并延长随访时间。
