Gore-Tex is a trademarked commercial name for expanded polytetrafluoroethylene (ePTFE) waterproof, breathable fabric. It was developed in the late 1960's in a patented process that creates a material that is breathable to water vapor, but impervious to liquids, as it has a microporous structure that is approximately 70% air, with pore size of about 1/20,000 the size of a water droplet or around 9 billion pores per square inch.Originally used in rainwear, shoes, and tents, Gore-tex fabric's porous nature and inertness in human tissue make it useful in medical applications where tissue ingrowth and vascularity occur. It has been made into artificial blood vessels, tissue patches, sutures, heart valves, and other applications.In plastic surgery, Gore-Tex is used as onlay grafts in rhinoplasty, tissue patches for chest wall reconstruction after cancer removal, abdominal wall reinforcement or hernia repair, and in sutures where strength, flexibility, and tissue incorporation are desirable charactersitics. I use Gore-Tex in facelifts, certain kinds of breast lifts, and as tissue replacement/reinforcement.The uses of Gore-Tex are limited only by the need and application-specific requirements, as well as the experience of the plastic surgeon in cosmetic and reconstructive surgery. It does not break down, is extremely durable, and although it can become infected, the very tissue ingrowth and vascularity that the product allows also serves as a way of protecting the material from bacterial infection.Gore-Tex has a long and safe medical use history. If your surgeon has suggested its use and you have more questions, please speak to your surgeon. You need not be afraid of its use at all. Choose your surgeon wisely and listen to his/her recommendations and discussion, not only about the surgical procedure and usage anticipated, but also about the pros and cons of any material planned for use in your surgery.
