    ObjectiveTo investigate the feasibility and effectiveness of using scar split thickness skin grafts combined with acellular allogeneic dermis in the treatment of large deep II degree burn scar.MethodsBetween January 2013 and December 2013, 20 cases of large deep II degree burn scar undergoing plastic operation were enrolled. There were 14 males and 6 females, aged 4 to 60 years (mean, 40 years). Burn reasons included hydrothermal burns in 10 cases, flame burns in 9 cases, and lime burns in 1 case. The burn area accounted for 70% to 96% total body surface area (TBSA) with an average of 79% TBSA. The time from wound healing to scar repair was 3 months to 2 years (mean, 7 months). Based on self-control, 0.7 mm scar split thickness skin graft was used to repair the wound at the right side of joints after scar resection (control group, n=35), 0.5 mm scar split thickness skin graft combined with acellular allogeneic dermis at the left side of joints (trial group, n=30). Difference was not statistically significant in the scar sites between 2 groups (Z=-1.152, P=0.249). After grafting, negative pressure drainage was given for 10 days; plaster was used for immobilization till wound healing; and all patients underwent regular rehabilitation exercises.ResultsNo significant difference was found in wound healing, infection, and healing time between 2 groups (P > 0.05). All patients were followed up for 6 months. According to the Vancouver Scar Scale (VSS), the score was 5.23 ± 1.41 in trial group and was 10.17 ± 2.26 in control group, showing significant difference (t=8.925, P=0.000). Referring to Activities of Daily Living (ADL) grading standards to assess joint function, the results were excellent in 8 cases, good in 20 cases, fair in 1 case, and poor in 1 case in trial group; the results were excellent in 3 cases, good in 5 cases, fair in 22 cases, and poor in 5 cases in control group; and difference was statistically significant (Z=-4.894, P=0.000).ConclusionA combination of scar split thickness skin graft and acellular allogeneic dermis in the treatment of large deep II degree burn scar is feasible and can become one of solution to the problem of skin source tension.
