We describe use of flexblock, a newly designed Medpor porous polyethylene implant. This implant is ideally suited for repair of small to medium-sized cranial defects and correction of contour deformities. Medpor is used for a wide variety of maxillofacial procedures, and its properties make it an excellent choice for the cranium. It is a highly stable and somewhat flexible porous alloplast that has been shown to exhibit rapid soft-tissue and bone ingrowth. Flexblock, which was designed as an onlay for calvarial bone graft donor sites, has a smooth exterior surface and a series of conical ridges on its undersurface that enable easy bending, good contour adaptability, and suitable strength. We used the Medpor flexblock implant in 12 patients over 2 years for correction of contour deformities, cranial defects, and reconstruction of the supraorbital rim. There were no complications. Larger cranial defects and complex reconstructions can be performed using customized Medpor implants. The properties of Medpor and the flexblock design make this implant an excellent alternative to the existing methods of cranioplasty and cranial contour correction.
我们描述了新型设计的Medpor多孔聚乙烯植入物flexblock的使用情况。这种植入物非常适合修复中小型颅骨缺损和矫正轮廓畸形。Medpor被用于多种颌面手术，其特性使其成为颅骨修复的理想选择。它是一种高度稳定且具有一定柔韧性的多孔异体材料，已证明能促进软组织和骨快速向内生长。设计用作颅骨骨移植供区覆盖物的flexblock，其外表面光滑，底面有一系列锥形嵴，便于弯曲，具有良好的轮廓适应性和合适的强度。我们在两年内对12例患者使用了Medpor flexblock植入物来矫正轮廓畸形、颅骨缺损和重建眶上缘。未出现并发症。使用定制的Medpor植入物可进行更大的颅骨缺损修复和复杂重建。Medpor的特性和flexblock设计使这种植入物成为现有颅骨成形术和颅骨轮廓矫正方法的极佳替代方案。
