Abstract: Objective:To explore the prevention and treatment methods of the scar deformity in pediatric deep burn.Methods:Forty children with deep burn were divided into the control group(17 cases) and treatment group(23 cases).The control group were not treated with early operation, and standard scar rehabilitation and functional exercise after discharge from hospital, the treatment group cases were treated with early escharectomy with dermatoplasty, and continuously standard scar rehabilitation and functional exercise guided by clinicians after discharge from hospital.The scars in two groups were evaluated using Vancouver Scar Scale on the day of discharge and in 1, 3, 6 and 12 months after discharge from hospital.Results:The Vancouver Scar Scale scores in the color, vascular distribution, thickness and flexibility of scar in treatment group were significantly better than those in control group in different time points after discharge from hospital(P<0.01).Conclusions:Early operation, continuously standard scar rehabilitation and functional exercise can effectively prevent and reduce the scar deformity and dysfunction in pediatric deep burn.
