Application of minimally invasive dermabrasion in deep second-degree facial burn wounds during the early postburn stage

Abstract Objective To explore the therapeutic effect of minimally invasive dermabrasion in deep second-degree facial burn wounds during the early postburn stage. Methods Thirty-five patients with deep second-degree facial burn wounds were treated with minimally invasive dermabrasion using the hydrodynamic debridement system within 2–4 days after injury. Then, wounds were covered with human biological dressings. We observed the wound infection rate, wound healing time and healing quality after debridement. Level of Evidence: Level V, therapeutic study. Result In this group of 35 patients with deep second-degree facial burn wounds, no infection was observed after debridement. The wound healing time was 9–17 days with an average healing time of 12.26 ± 2.15 days. The wound healing quality was satisfactory. The healing scars of the burn wounds were assessed using the Vancouver Scar Scale and had an average score of 0.86 ± 0.84. Conclusions Minimally invasive dermabrasion during the early postburn stage can reduce wound infection, prevent wound deepening, shorten wound healing time, improve wound healing quality, and reduce the occurrence of pigmentation and scar hyperplasia contracture deformity. Therefore, minimally invasive dermabrasion during the early postburn stage is of great significance in the treatment of deep second-degree facial burn wounds.
