Abstract：Objective To evaluate the clinical efficacy and safety of fractional CO2 laser combined with high frequency electrocoagulation in the treatment of pyogenic granuloma.Methods A total of 116 patients with pyogenic granuloma were randomly divided into two groups:treatment group(60 cases) treated by fractional CO2 laser combined with high-frequency electrocoagulation and control group (56 cases) treated singly by high-frequency electrocoagulation.The efficacy was valued 3 weeks after each treatment and the adverse reactions were recorded in the following 6 months after the last treatment.Results The cure rate of single treatment in treatment group (96.67％) was significantly higher than that in the control group (78.57％).The wound healing time (7.65±1.31 days) in the treatment group were shorter than that in the control group (8.74±1.48 days),and the scar formation rate (3.33％) in the treatment group was lower than that in the control group (21.43％).The above differences had statistical significance(P＜0.05).In addition,the incidence of pigmentation in the treatment group was 6.7％ and no infection case was found,while 14.29％ & 7.14％ for the same items in the control group.No obvious bleeding occurred in the both two groups.Statistical analysis showed that the differences of the above three indicators between the two groups had no statistical significance(P＞0.05).Conclusion Treating pyogenic granuloma by fractional CO2 laser combined with high frequency electrocoagulation has the following advantages:high cure rate of single treatment,quicker wound healing,less bleeding,lower incidences of pigmentation,infection and scar,meanwhile has better curative effect and safety than single high frequency electrocoagulation therapy.
