Due to the different handling properties of unsintered hydroxyapatite particles/poly-L-lactic acid (uHA/PLLA) and polycaprolactone (PCL), we compared the surgical outcomes and the postoperative implantation accuracy between uHA/PLLA and PCL meshes in orbital fracture repair.
.
Patients undergoing orbital wall reconstruction with PCL and uHA/PLLA mesh, between 2017 and 2019, were investigated retrospectively. The anatomical accuracy of the implant in bony defect replacement and the functional outcomes such as diplopia, ocular motility, and enophthalmos were evaluated.
.
No restriction of eye movement was reported in any patient (n=30 for each group), 6 months postoperatively. In the PCL group, no patient showed diplopia or enophthalmos, while the uHA/PLLA group showed two patients with diplopia and one with enophthalmos. Excellent anatomical accuracy of implants was observed in 27 and 22 patients of the PCL and uHA/PLLA groups, respectively. However, this study showed that there were neither any significant differences in the surgical outcomes like diplopia and enophthalmos nor any complications with the two well-known implants.
.
PCL implants and uHA/PLLA implants are safe and have similar levels of complications and surgical outcomes in orbital wall reconstruction.
由于未烧结的羟基磷灰石颗粒/聚-L-乳酸（uHA/PLLA）和聚己内酯（PCL）的处理特性不同，我们比较了uHA/PLLA和PCL网片在眼眶骨折修复中的手术效果和术后植入准确性。
回顾性研究2017年至2019年间接受PCL和uHA/PLLA网片眼眶壁重建的患者。评估植入物在骨缺损替代中的解剖准确性以及复视、眼球运动和眼球内陷等功能结果。
术后6个月，每组30例患者均未报告眼球运动受限。PCL组无患者出现复视或眼球内陷，而uHA/PLLA组有2例患者出现复视，1例出现眼球内陷。PCL组和uHA/PLLA组分别有27例和22例患者植入物的解剖准确性极佳。然而，本研究表明，在复视和眼球内陷等手术结果方面，这两种知名植入物均无显著差异，也未出现任何并发症。
PCL植入物和uHA/PLLA植入物在眼眶壁重建中是安全的，并发症和手术结果水平相似。
