Prognostic Analysis of Skin Scar Loosening and Tissue-Expansive Autologous Skin Grafting in the Treatment of Skin Postburn Scars.

Abstract

This study aims to observe and investigate the clinical value of scar loosening and tissue-expansive autologous skin grafting in the treatment of postburn scars and independent risk characteristics for surgery-related complications. We retrospectively analyzed 94 cases with postburn scars, and all patients were treated with scar loosening and autologous skin grafting. Overall therapeutic effects were evaluated using the standard of cure and improvement of clinical diseases. Burn Specific Health Scale-brief was used to analyze patients' quality of life. The visual analog scale scores were used to analyze esthetic satisfaction. Surgery-related complications were recorded, and logistic regression model was used to analyze independent factors affecting surgery-related complications. As for overall efficacy evaluation, 50 cases were cured, 19 cases were markedly improved, 17 cases improved, and 8 cases were detected and tested, and the overall effective rate was 91.4%. The Burn Specific Health Scale-brief and visual analog scale score showed a trend of increasing gradually. It indicated that the patients were satisfied with the operation and their quality of life was improved. The logistic regression model showed that history of skin disease (OR=1.53 (1.08-2.16), P =0.02) and skin area (OR=2.50 (1.22-4.50), P <0.01) were significantly associated with surgery-related complications. Scar loosening and autologous skin grafting is a safe and effective treatment. The history of skin disease and skin area was the independent factors for surgery-related complications.
