Title: Preparation and processing of human allogenic dermal matrix for utilization in reconstructive surgical procedures

Abstract: AIM: This article presents the development of a novel preparation and processing method as well as indication for clinical applications of human allogeneic acellular dermal matrix, which was developed originally in the Central Tissue Bank (CTB) for use in burn medicine and reconstructive surgery.
METHODS: Acellular dermal matrix (ADM) is a biological material assigned for utilization in several surgical procedures due to its unique structure and advantageous properties. The article focuses on a novel preparation and processing method developed by CTB, which differs in its impact on the structure, biological and biomechanical properties of the final ADM compared to the wide range of commercially available ADM products and currently available ADM products of other tissue banks.
RESULTS: The ubiquitous acellular allogeneic dermal collagen matrix is the main substance participating in advantageous properties facilitating the use of ADM in numerous indications from dermal replacement and soft tissue augmentation to more extensive surgical reconstructive procedures. Dermal substitutes play an essential role in the reconstruction of full-thickness skin defects, both in acute and chronic wounds, defects of fasciae, peritoneum, etc., and there is a strong evidence that they can improve the final scar quality as well. Differences in preparation methods of ADMs are recently causing concerns among surgeons utilizing the ADMs. We present three different cases with favourable outcomes by using human acellular ADM grafts.
CONCLUSIONS: Although ADMs did not fulfil all of the requirements for an ideal dermal substitute, their applications have been advanced for diverse indications in soft tissue reconstructions and augmentations. Early revascularization of the allografts reduces bacterial contamination. Research and development of new generation of acellular dermal matrices with incorporated autologous in vitro cultured cells will likely yield new products and give new hope for continued improve­ments in functional and cosmetic outcomes (Fig. 9, Ref. 60).
Keywords: human acellular allogeneic dermal matrix, skin and dermal substitutes, reconstructive surgery, wound healing.
