The use of MatriDerm® and skin grafting in post‐traumatic wounds

The aim of this study was to prove the effectiveness of MatriDerm® combined with skin grafting versus skin grafting alone in post‐traumatic wounds treatment. At the Department of Plastic and Reconstructive Surgery of the University of Rome Tor Vergata, we treated 60 patients: 30 patients with dermal substitutes (MatriDerm®) combined with autologous skin graft and 30 with skin graft alone. Two weeks after the first treatment, 95% of wounds treated with MatriDerm® and skin graft showed a re‐epithelisation, whereas it was 75–80% in the control group. We used the Manchester Scar Scale (MSS) and patient's self‐estimation scale to assess the outcomes. Mann–Whitney U test was performed for the five items of the MSS and the results were combined to those of patient's self‐estimation scale and the re‐epithelialisation percentage to test the significance between the two groups. These data confirm the evidence of the clinical use of MatriDerm® technology in the healing of soft tissue wounds and prove the effectiveness of combining MatriDerm® and skin grafting for the first time. Furthermore, we observed a percentage reduction of wound contraction and in the same time an improvement of elasticity, quality of scars tissue and dermal architecture.
