Treatment of seborrheic keratosis by flat-cutting:a clinical observation

Abstract

Objective To compare the curative effect,patient's satisfaction degree,and adverse reaction on seborrheic keratosis by level-cutting and frozening with liquid nitrogen.Methods 68 cases were randomly divided into liquid nitrogen frozening group(32 cases,group A)and flat-cutting group (36 cases,group B).Liquid nitrogen was spurted until freeze-thaw status in group A,and the ramnant skin lesion needed for other treatments,but no more than 3 times.The skin lesion in group A was completely resected with scalpel following its basilar part after local anesthesia,and elaeoyarn was pressurized to stop bleeding on wound,which was removed afer 5 days.The effects,satisfactory degree and adverse reaction were analyzed after 3 mouths of treatment.Results The effect and satisfactory degree in group B was significantly better than that in group A(P＜0.01),but the adverse reaction in group B was significantly lower than that in group A(P＜0.05).Conclusion Compared with liquid nitrogen frozening,the therapy of flat-cutting has advantages to seborrheic keratosis,with good efficacy,high patient's satisfaction and low adverse reaction.
