Methods Eighty-five patients with verrcua plantaris were divided into two groups randomly. Forty-five patients in treatment group were treated by CO2 fractional laser combined with liquid nitrogen cryotherapy. Forty patients in control group were treated by liquid nitrogen cryotherapy alone. As a period for 10 days,two groups had been given 3 periods of treatment. Symptom / sign scores were evaluated at the beginning and at the 10 th day end of the treatment. The patients were followed- up for six months to observe their recurrence rates. Results The cure rates in treatment group and control group were 93. 33% and 52.50%; the recurrent rates in treatment group and control group were 2. 38% and 23. 81%; the symptom score in treatment group and control group were 0. 67 ± 0. 31 and 2. 25 ± 1. 48.
