ReviewEvolution of silicone therapy and mechanism of action in scar management.
Silicone-based products are widely used in the management of hypertrophic scarring and keloids. This review discusses the range of products available and the clinical evidence of their efficacy in preventing excessive scarring and improving established scars. ⋯ Results from clinical trials and clinical experience suggest that silicone gel is equivalent in efficacy to traditional silicone gel sheeting but easier to use. The mechanism of action of silicone therapy has not been completely determined but is likely to involve occlusion and hydration of the stratum corneum with subsequent cytokine-mediated signaling from keratinocytes to dermal fibroblasts.

Alternative techniques in reconstructive surgery: bone-anchored extraoral implants for burn cases.
The authors present their experience with the use of extraoral implants for reconstruction of the ear area after burns. The first step of the protocol includes positioning of implants in the mastoid process. The second step, after 3 to 4 months, is to realize the auricle prosthesis and apply it. Extraoral, bone-integrated implants offer low surgical risks and few postsurgical complications, leading to optimal aesthetic results, mainly in the ear area. Compared with traditional surgery techniques, the aesthetic results are better, with less surgery, possibly only two surgery sessions. Adhesive prostheses can be placed without the usual local irritation, and a more correct positioning can be obtained. ⋯ The authors believe that bone-anchored implants for the treatment of auricle burns is a valid and brilliant technique that complements traditional reconstructive procedures. The advantages are the low incidence of long-term complications and the possibility of obtaining excellent aesthetic lasting results even for very complicated cases that would not have been solved in the past.

Case ReportsComplications from repeated injection or puncture of old polyacrylamide gel implant sites: case reports.
Polyacrylamide gel has been used for soft tissue augmentation outside the United States since 1997. Despite some adverse events, the long duration of the augmentation and the tangible filling effect has increased its use in Asia and the Middle East. In this era of mesotherapy and fillers, patients are more likely than ever to have additional injections. ⋯ Puncture of the implant violates the tissue-implant barrier and induces inflammation or introduces bacteria that are not detectable in culture but may contribute to inflammation in the presence of the filler material. Further research is needed to assess the inflammation observed with repeated puncture of old polyacrylamide gel implants and its implications. In the meantime, patients should be warned about the possibility of inflammation in the case of puncture or surgery to the implant site, even years after the polyacrylamide gel injection.
