Porous Polyethylene Implants

ABSTRACT Introduction Patients undergoing complex rhinoplasty, following previous trauma or cartilage deteriorating disease processes, present a surgical challenge. The availability of septal cartilage maybe limited, and alternative graft materials should be considered. Methods A retrospective study of our experience using the porous polyethylene (Medpor®) implant in nasal reconstruction was conducted. The indications for surgery are reviewed and the surgical outcomes noted. We also review the literature on available nasal implants and discuss their advantages and disadvantages. Results A total of 22 Medpor® nasal implants were used for augmentation rhinoplasty over a 6 and half years period. Three patients experienced a surgical complication, including one slipped dorsal implant, and two patients with graft extrusion. Both of these two patients had concomitant disease processes that would have resulted in a poor tissue microenvironment, which may have contributed to their graft failures. Conclusion In our experience, the Medpor® implant has proved very successful in patients requiring complex rhinoplasty, in a normal host tissue microenvironment.

Porous Polyethylene Implants

Purpose The purpose of this study is to evaluate the intra- and post-operative performance and safety of direct three dimensional printing (3DP) porous polyethylene implants in cranial reconstruction. Design/methodology/approach Prefabricated porous polyethylene implants were prepared by direct 3DP, and cranioplasty implantation was performed. Postoperative aesthetics, patient satisfaction, firmness of the implant, reactions to the implant and 3D computed tomography (CT) scanning were assessed after 2, 6, 12 and 24 months postoperatively. Findings No complications after surgery were encountered. Excellent aesthetic results were obtained in all cases, and all the patients were satisfied with the reconstruction outcome. Bone density structure was found to ingrowth into these direct 3DP porous polyethylene implants and the content increased with increasing follow-up times. Research limitations/implications This study was a pilot study conducted in a single group and evaluated in a short-term period. The bone formation and ingrowth were indirectly assessed by 3D CT evaluation. Originality/value This work reported the use and evaluation of direct 3DP porous polyethylene in middle- to large-sized cranial reconstructions. It evidently showed the bonding of implants to surrounding tissues which would result in the long-term stability and infection resistance of the implant.
