Randomized Controlled Trial Study on the Clinical Efficacy of Liquid Nitrogen and Dimethyl Ether Cryotherapy for Viral Warts

To analyze the efficacy of liquid nitrogen and dimethyl ether cryotherapy for the treatment of viral warts, 480 patients with viral warts admitted to our hospital from March 2022 to June 2024 were selected. 228 patients were randomly assigned to the comparison group and treated with liquid nitrogen cryotherapy, while 252 patients were assigned to the observation group and treated with dimethyl ether cryotherapy. The clinical efficacy and adverse reactions of both treatments were observed and compared. The results showed that there were no significant differences in the cryotherapy efficacy between the two groups. The analysis suggests that both liquid nitrogen and dimethyl ether are equally effective for treating viral warts, with dimethyl ether showing lower adverse reaction rates and more tolerable pain levels, which offers higher clinical application value.
