Evaluation of lip augmentation with Gore-Tex facial implant. 
Although numerous materials, including autogenous, homogeneous, and alloplastic materials, have been used for lip augmentation with varying degrees of success, no ideal one has been found to achieve a soft and long-lasting result.  Gore-Tex implant has been successfully used in cardiovascular surgery.  So far, it has not been used much in lip augmentation.  In this study, a Gore-Tex SAM facial implant (1.8 mm in diameter) was used for lip augmentation in 23 lips of 17 female patients.  In 10 consecutive lips with three segments of the implant each, a computer-assisted imaging system was used to scrutinize the results.  The results have shown that the three segments of the implant enhanced the lip projection with about 0.98 mm in mean (p < 0.01) and the exposed vermillion width with about 1.  94 mm (p < 0.01) in the over 6 months follow-ups.  No major complications, only some minor ones, were seen.  For lip augmentation, we find that only minor changes can be achieved with three segments of the Gore-Tex facial implant.  We feel that it is safe and believe it gives a permanent result which is not the case with collagen injection and usually not the case with lipofilling despite reinjections.  Furthermore, we consider the implant quite expensive at present.
