Randomized Controlled Trial[A prospective randomized controlled clinical study on the treatment of hypertrophic scar after burn by fractional carbon dioxide laser combined with autologous fat injection].
Objective: To explore the clinical effects of fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn. Methods: From April 2018 to April 2019, 12 patients with hypertrophic scar after burn who met the inclusion criteria were admitted to the Department of Plastic Surgery and Burns of Xuzhou Renci Hospital, and were included in this prospective randomized controlled clinical study. There were 7 males and 5 females with age of (32±11) years and scar area of (612±195) cm(2). ⋯ Before the first treatment, the blood flow of scars in both groups was abundant; 6 months after the last treatment, the blood flow of scars in combined treatment group was significantly less than that in laser alone group. Conclusions: Fractional carbon dioxide laser combined with autologous fat injection in the treatment of hypertrophic scar after burn can significantly reduce the pain and itching symptoms of scar, and improve the thickness, texture, and congestion of scar. The combined treatment has synergistic effect and less adverse reactions, providing a more effective treatment for patients with hypertrophic scar.
