Porous high-density polyethylene (Medpor) is a biocompatible large-pore, high-density polyethylene implant. It is well tolerated by surrounding tissue, and its porous structure is rapidly infiltrated by host tissue. It is a highly stable and somewhat flexible porous alloplast that has rapid tissue ingrowth into its pores. However, when the implant is placed under a thin cover of skin, there is a risk of exposure. A total of 52 Medpor implants were placed in 31 patients over a four-year period. The implants were used for the chin, malar area, nasal reconstruction, ear reconstruction, orbital reconstruction, and the correction of mandibular contour deformities. Many of these implants were placed in areas considered problematic, such as those with thin or atrophic soft-tissue coverage and extensive scarring. There were nine complications, including three patients in whom the implant was exposed; these are presented here.

Systematic Review of Medpor Versus Autologous Ear Reconstruction.

Authors:
Yangmyung Ma Mark Sheldon Lloyd

J Craniofac Surg 2022 Mar-Apr 01;33(2):602-606

Birmingham Women's and Children's Hospital NHS Trust, Birmingham, United Kingdom.

Abstract: Ear reconstruction is 1 of the most technically challenging sub-specialties of craniofacial and reconstructive plastic surgery. The reconstructive ear must not only fulfil the requirement of being aesthetically pleasing but must also have good vascularity with a low complication rate. Several ear reconstructive techniques have been developed such as the autologous ear reconstruction technique using costal cartilage and ear reconstruction with high-density porous polyethylene or Medpor (Porex Surgical, Inc, College Park, GA).

Department of Plastic, Reconstructive and Hand Surgery, Amsterdam UMC, University of Amsterdam, Amsterdam, the Netherlands.

Background: Auricular reconstruction for microtia is most frequently performed using autologous costal cartilage (ACC) or porous polyethylene (PPE) implants. Short-term results are generally promising, but long-term results remain unclear. Long-term outcomes were explored in this systematic review, and minimal reporting criteria were suggested for future original data studies. Read More
