[Use of skin substitutes in treatment of large hypertrophic scars due to burn injury].

The study concerns a clinical experiment in two patients with a dermal substitute based on atelocollagen and hyaluronic acid, and allogeneic acellular dermis. In both cases two-step grafting was performed. At the first step the dermal substitute was implanted into the wound and it was grafted at the second step with thin dermoepidermal autograft. Large hypertrophic scars after burn injury were treated. In both patients the quality of skin cover was significantly improved.
