Clinical analysis of patients with pyogenic granuloma treated with microwave

Objective To evaluate the efficiency and side-effect in the patients with pyogenic granuloma treated with microwave. Methods Totally 79 cases were randomly assigned to microwave treatment group(39 cases) and control group treated by liquid nitrogen(40 cases). The efficaly and side-effectwere observed. Rusults Complete resolution of the pyogenic granuloma was achived in all patients in microwave treatment group and 29 cases in control grouprespectively.The effectiveness rate of microwave treatment group signifcantly superior than that of the control group(P=0.000).Hypopigmentation was observed in 1 patients of microwave treatment group and 8 patients of control group,respectively. There was statistically signifcantly differences of hypopigmentation rate between these two treatment methods. There were a flat imperceptible scar in 6 patients of microwave treatment group and 5 patients of control group,respectively. No signifcantly differences of scar rate between these two treatment methods. Conclusion pyogenic granuloma can be treated effectively and simply with microwave.
