Two commonly used implant materials for aesthetic facial augmentation[1] 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]).[2] EPTFE implants have micropores on the surface that allow for tissue ingrowth, stabilization, and avoidance of a capsule.[2] However, these have the potential for long-term deformation due to shrinkage.[2] 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.
