Facial Augmentation using Expanded Polytetrafluoroethylene Covered Silicone
07 April 2017 (online)
Two commonly used implant materials for aesthetic facial augmentation are solid silicone (silastic) and expanded polytetrafluoroethylene (ePTFE; Gore-Tex, W. L. Gore and Associates, Flagstaff, AZ). The main shortcomings of silicone are capsular formation and implant visibility ([Fig. 1]). EPTFE implants have micropores on the surface that allow for tissue ingrowth, stabilization, and avoidance of a capsule. However, these have the potential for long-term deformation due to shrinkage. The rationale for the composite implant is that it offers the benefits of silicone (maintenance of form, natural feel) with the biocompatibility of ePTFE coating as a biological interface. In this letter, we aim to examine our indications and outcomes with this material.
