Orbital wall reconstruction remains a challenge in reconstructive CMF surgery due to the delicate anatomical structures and their potential functional impairment due to inefficient treatment. The use of biomaterials in reconstructive surgery has revolutionised the therapy in this area. Ultra-high molecular weight polyethylene (UHMWPE) has shown promising results due to its biocompatibility, mechanical properties, and versatility. This paper presents the first clinical study of the use of UHMWPE in orbital fracture reconstruction.
In a multicentre prospective study consisting of 50 patients undergoing orbital floor reconstruction, UHMWPE implants were used to reconstruct the orbital volume after fracture. 46 Patients underwent preoperative and postoperative 3D radiography and orbital volume segmentation.
A significant postoperative volume reduction of the affected orbits was observed in the entire cohort ( < 0.001) with a significant alignment to the healthy contralateral orbits. There were no implant-related complications.
Orbital wall reconstruction with UHMWPE (marPOR) implants is a reliable method to restore adequate orbital volume for functional and aesthetic recovery in trauma patients.
由于眼眶壁解剖结构精细，且治疗不当可能导致功能受损，眼眶壁重建在颅颌面重建手术中仍然是一项挑战。生物材料在重建手术中的应用彻底改变了该领域的治疗方法。超高分子量聚乙烯（UHMWPE）因其生物相容性、机械性能和多功能性而显示出有前景的结果。本文介绍了使用UHMWPE进行眼眶骨折重建的首例临床研究。
在一项多中心前瞻性研究中，50例患者接受了眶底重建，使用UHMWPE植入物在骨折后重建眼眶容积。46例患者在术前和术后进行了三维放射摄影和眼眶容积分割。
在整个队列中观察到患侧眼眶术后容积显著减小（<0.001），且与对侧健康眼眶显著对齐。未出现与植入物相关的并发症。
使用UHMWPE（marPOR）植入物进行眼眶壁重建是一种可靠的方法，可为创伤患者恢复足够的眼眶容积，以实现功能和美学恢复。
