Background:
Autologous split-thickness skin grafts (STSGs) remain the mainstay for treatment of large skin defects. Despite its many advantages, there exist critical disadvantages such as unfavorable scar and graft contracture. In addition, it cannot be used when structures such as tendons and bones are exposed. To overcome these limitations, acellular dermal matrix (ADM) is widely used with STSG. CGDerm Matrix®, which was recently developed, is a novel reprocessed micronized ADM (RMADM). In this study, outcomes of the combined application of RMADM and STSG on full-thickness wounds were analyzed.
Methods:
Forty-one patients with full-thickness skin defects due to trauma, scar contracture release, and diabetic foot ulcers, who underwent STSGs, from January 2021 to July 2021, were retrospectively reviewed. The primary outcome of interest was skin loss rate, which was measured 14 days after surgery.
Results:
The most common cause of skin defect was trauma (36 patients), diabetic foot (2 patients), scar contracture release (2 patients), and malignancy (1 patient). The average defect size was 109.6 cm2 (range, 8-450 cm2). The average skin loss rate was 9.1%, showing a graft take rate of > 90%.
Conclusion:
The use of combined RMADM and STSG in full-thickness wound reconstruction provides stable and acceptable outcomes. The newly developed ADM can be a promising option in wound reconstruction.
