: These data confirm the evidence of using PRP technology in the healing of both soft- and hard-tissue wounds. Moreover, the satisfaction of the patient confirms the quality of this study's results.

Management of complex abdominal defects remains a significant challenge for many surgeons, especially in contaminated fields. Currently, available biosynthetic grafts include human cadaveric dermis (AlloDerm), porcine dermal (Permacol and Strattice), and submucosal (Surgisis) sources. All these grafts are composed of an acellular collagen scaffold to provide a bridge for tissue incorporation and neovascularization. The authors describe a case report of a woman who required dual mesh explantation and successive reparative surgery using a porcine dermal matrix for a complex and infected abdominal wound. Twelve months postdischarge the patient remains well, she is pain free, and she returned home to full activities with complete wound closure and without any evidence of residual or recurrent hernia. The patient was satisfied with her cosmetic results. In conclusion, the authors' experience shows that the use of Permacol, a porcine dermal matrix, has been successful in treating an infected abdomen and a vast abdominal wall defect.

Extra-oral implants represent a valid alternative technique in aesthetic reconstruction of the craniofacial district in oncology surgery. Two female patients were selected; they were treated from December 2001 to June 2007 by implanting auricular epithesis. The age range was 27 years. They shared the same diagnosis: burns of the auricle-temporal region. The deformity in the auricle region and the complete absence of the pinna convinced the authors to choose this reconstructive method. Most patients showed a good stability of fixtures, epithesis and perimplants soft tissue, in some cases there has been a delay in the time to healing soft tissue perimplant and only one patient has removed the plant after 5 years cancer recurrence. No complications were observed, including bleeding and infections, in the postsurgery period. No report was made in any case of lesion of the facial nerve having the fixtures being positioned in the back and above the point of emergency.

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.
