Background: The efficacy of pulsed dye laser combined (PDL) and UltraPulse fractional CO2 in treatment of hypertrophic scars is well documented. The present study investigates the efficacy of moist exposed burn ointment (MEBO)/moist exposed burn therapy (MEBT) in postlaser wound management.
Methods: Sixty-one patients with immature, red hypertrophic scars were enrolled in this clinical trial. Patients were randomly divided into two groups: (a) the MEBO treatment group (n = 30) and (b) the control group (n = 31) treated with chlortetracycline hydrochloride ointment. Demographic data such as age, gender, and cause of scars were recorded. A visual analogue score (VAS) was collected to measure pain at 1, 6, 24, 72 hours, and 7 days post-treatment. The Vancouver Scar Scale (VSS) was used to determine the response of the scars before and 3 months after the treatment. The wound healing time and pigmentation scores were also recorded.
Results: No significant differences were found in age, gender, and etiology of the scars in the two groups. The VAS scores in MEBO group were significantly lower than the control group within the first 3 days after treatment. The wound healing time of the MEBO group was significantly shorter than the control group. For both groups, VSS scores were significantly decreased and the scar markedly improved. However, the VSS scores were significantly lower in the MEBO group compared with the control group 3 months after treatment and pigmentation formation was dramatically lower in MEBO group compared with the control.
Conclusion: MEBT/MEBO treatment reduced the post-treatment pain, shortened the wound healing duration, promoted the overall scar condition, and reduced the incidence of pigmentation.
