In augmentation surgery, one of the important considerations is the selection of artificial implants. Recently, medium-porosity and high-density expanded polytetrafluoroethylene(ePTFE), which has high biocompatibility without gradual loss of volume, has been used as an implant, however, there are not many cases and reports on the post-operative complications and patient satisfactions. Between 2006 and 2009, a total of 23 patients with a flat or depressed forehead/temple underwent augmentation with medium-porosity and high-density ePTFE at our hospital. During follow up periods, 15 patients visited the clinic to fill out a survey and receive a physical examination for any complications, whereas 8 patients underwent a survey on the phone. The patients were asked questions to score their satisfaction rates on a scale of 1 to 10 points. There were no post-operative complications, and, the average score of satisfaction rates on the survey was 8.3 points. Since there were no complications and high rates of satisfaction during follow up periods, this medium-porosity and high- density ePTFE could be considered as a durable implant.
