The aim of this study was to compare the effectiveness of porous polyethylene, titanium mesh, and castor oil-derived biopolymer randomized in orbital reconstructions of defects larger than 1 cm in length on the inferior and medial walls. A total of 63 patients (64 orbits) were evaluated to determine the presence of diplopia, enophthalmos ocular motility, and infraorbital nerve paraesthesia in both the preoperative and postoperative periods. The surgeons' opinions of the ease in handling the implants were also obtained after each procedure. The patients were divided into 3 groups: 17 received porous polyethylene, 21 received castor oil-derived biopolymer, and 26 received titanium mesh. In the preoperative period, 30 patients experienced enophthalmos, 11 experienced diplopia, and 12 experienced ocular motility. Ninety days after the orbital reconstruction, 6 cases of enophthalmos persisted, as did 2 cases of diplopia and 2 cases of ocular motility. Ten patients developed some type of postoperative complication. Material removal was required in only 1 case. Regardless of the size of the defect, the materials used were found to be effective for reconstructing orbital volume; they were also found to offer ease in handling and stabilization.
本研究的目的是比较多孔聚乙烯、钛网和蓖麻油衍生生物聚合物在眼眶下壁和内侧壁长度大于1厘米的缺损眼眶重建中的有效性。共评估了63例患者（64只眼眶），以确定术前和术后复视、眼球内陷、眼球运动及眶下神经感觉异常的情况。每次手术后还收集了外科医生对植入物操作难易程度的意见。患者分为3组：17例接受多孔聚乙烯，21例接受蓖麻油衍生生物聚合物，26例接受钛网。术前，30例患者出现眼球内陷，11例出现复视，12例出现眼球运动障碍。眼眶重建9天后，仍有6例眼球内陷、2例复视和2例眼球运动障碍。10例患者出现了某种术后并发症。仅1例需要取出材料。无论缺损大小，所用材料对眼眶容积重建均有效；它们还易于操作和固定。
