Evaluation of Scar Quality after Treatment of Superficial Burns with Dressilk(®) and Suprathel(®)—In an Intraindividual Clinical Setting

Background: Various synthetic and biological wound dressings are available for the treatment of superficial burns, and standard care differs among hospitals. Nevertheless, the search for an ideal wound dressing offering a safe healing environment as well as optimal scar quality while being economically attractive is a continuing process. In recent years, Dressilk(®), which consists of pure silk, has become the standard of care for the treatment of superficial burns in our hospital. However, no long-term scar-evaluation studies have been performed to compare Dressilk(®) with the often-used and more expensive Suprathel(®) in the treatment of superficial burns. Methods: Subjective and objective scar evaluations were performed three, six, and twelve months after treatment in patients who received simultaneous treatment of 20 superficial burn wounds with both Suprathel(®) and Dressilk(®). The evaluations were performed using the Vancouver Scar Scale, the Cutometer(®), Mexameter(®), Tewameter(®), and the O2C(®). Results: Both dressings showed mostly equivalent results in subjective scar evaluations. In the objective scar evaluations, the wounds treated with Dressilk(®) showed a faster return to the qualities of non-injured skin. Wound areas treated with the two dressings showed no significant differences in elasticity and transepidermal water loss after 12 months. Only oxygen saturation was significantly lower in wound areas treated with Suprathel(®) (p = 0.008). Subjectively, wound areas treated with Dressilk(®) showed significantly higher pigmentation after six months, which was not apparent after 12 months. Conclusion: Both wound dressings led to esthetically satisfying scar recovery without significant differences from normal uninjured skin after 12 months. Therefore, Dressilk(®) remains an economically and clinically interesting alternative to Suprathel(®) for the treatment of superficial burns.
