Treatment comparison between warts and pigmental nevus by using new -type CO_2 laser

Objective To evaluate curative effect of new type CO2 laser on warts and pigmental nevus treatment. Methods Both of diseases were treated with the same therapy. We evaluated whether there was apparent difference in cure rate and treatment mean impulse times. In this project, there were 78 patients, among which, 26 cases suffered two diseases. Results Cure rate of warts was 94.2%and that of pigmental nevus was 73.1%. The former was higher than the latter apparently (P< 0.01). But the treatment mean impulse times had no difference (P >0.1). Conclusion One off cure rate of wart is higher than that of pigmental nevus.
