A randomized controlled trial of hydrocolloid dressing in the treatment of hypertrophic scars and keloids

BACKGROUND. Silicone gel sheeting has been investigated for use in the treatments of keloids and hypertrophic scars. Its mechanism of action may be related to scar hydration. OBJECTIVE. The purpose of the present study was to evaluate a hydrocolloid occlusive dressing that also acts by promoting a moist environment. METHODS. In a randomized controlled prospective study, patients were allocated to receive hydrocolloid dressing or moisturizer to keloids or hypertrophic scars. Scar size and volume, color, patient symptoms, and transcutaneous oxygen measurements were taken. RESULTS. There tons significantly reduced itching (P < 0.03), somewhat reduced pain (P < 0.08) and increased pliability (10%) for both treatments over 2 months. CONCLUSION. Hydration of the scar for 2 months resulted in symptomatic improvement, but no change in physical parameters.
