Abstract

Purpose: Despite there being different materials for orbital floor reconstruction available today, outcomes are still not satisfying. In recent years, ultra-high molecular weight polyethylene (UHMWPE) has gained popularity in the field of orthopedic surgery due to its good biocompatibility and low infection rate. With its three-dimensional compound structure, it combines high stability and ductility, making it a potential material to be used for orbital floor reconstruction.

Methods: In a cadaver study, an overall of eighteen orbits were included. Fractures of the inferior wall were induced and then reconstructed using Polyglactin 910/PDS composite (Ethisorb) and UHMWPE (marPOR). Orbits were scanned by cone-beam CT in each condition: Intact, fractured and reconstructed with Ethisorb, marPOR 0.85 mm and marPOR 1.5 mm. Segmented orbital volumes were calculated by specialized software (Disior bonelogic CMF).

Results: All materials led to sufficient reconstruction of the initial orbital volumes (Ethisorb: p < 0.001; marPOR 0.85 mm: p = 0.003; marPOR 1.5 mm: p < 0.001). Orbits that were reconstructed with marPOR 0.85 mm showed the least mean volume difference from intact orbital volumes.

Conclusion: UHMWPE (marPOR) offers reliable reconstruction of orbital floor fractures combined with good stability, ductility and biocompatibility.

超高分子量聚乙烯（marPOR）是一种适用于重建人Cadaver眶底骨折缺损的材料

目的：尽管目前有不同的材料用于眶底重建，但结果仍不令人满意。近年来，超高分子量聚乙烯（UHMWPE）因其良好的生物相容性和低感染率在骨科手术领域得到了广泛的应用。它具有三维复合结构，具有较高的稳定性和延展性，是轨道地面重建的潜在材料。方法：在尸体研究中，共包括18个轨道。采用聚乳酸910/PDS复合材料（Ethisorb）和UHMWPE （marPOR）诱导下壁骨折重建。在两种情况下，分别用Ethisorb、marPOR 0.85 mm和marPOR 1.5 mm对眼眶进行完整、断裂和重建。用专用软件（Disior bonologic CMF）计算分割后的眶体积。结果：所有材料均能充分重建初始眼眶体积(Ethisorb: p 0.001；marPOR 0.85 mm: p = 0.003；marPOR 1.5 mm: p 0.001)。用marPOR 0.85 mm重建的轨道与完整轨道的平均体积差异最小。结论：超高分子量聚乙烯（marPOR）具有良好的稳定性、延展性和生物相容性，是可靠的眶底骨折重建材料。
