Objective To evaluate the effect of treating epistaxis with radiofrequency and laser via endoscopies.Methods 343 epistaxis patients with similar symptoms and signs were enrolled and randomly divided into two groups to be treated either with radiofrequency or laser via endoscopy.Primary healing rate,surgery duration and halt frequencies were compared as well as the patients discomfort and surgeons' metal pressure stree level were measured with VAS Visual Analogue Scales(VAS).Results The primary healing rates between the radiofrequency group and the laser group were 96.4% (186 cases/ 193 sides)and 94.7%(179 cases /189 sides),the difference was not statistically significant(P>0.05).The surgery duration in radiofrequency group 2.54±0.93 was shorter than that in the laser group 4.65±1.47(P<0.05);the halt frequencies in the radiofrequency group was 1.21 ±0.31 during surgery and the need of stanching was less than that in the laser group 2.87±1.47(P<0.05);the surgeons' stree level in the radiofrequency group was 2.84±0.72 which was lower than that in the laser group 5.07±1.26(P<0.05);all the above results showed statistical significante difference.There was no statistical significance in patients' discomfort grade between the radiofrequency group 6.73±2.06 and the laser group 6.91±1.78(P>0.05).Conclusions Strictly follow the rules of the procedure,satisfactory outcome can be achieved with these two methods.There is no significant difference in the treating effects and patient discomfort level between the two methods if carefully handled.Radiofrequency has more advantages in treating epistaxis in surgery duration,halt frequency and surgeons' stress level.

鼻出血是耳鼻喉科最常见的急症之一,其发病非常普遍,病因甚多,有些病人因反复多次出血影响了正常的工作、学习和生活[1,2].临床针对鼻出血病人首先以对症治疗为主,即紧急止血,预防再度出血.
