2.3. Cryotherapy
The feet were soaked in diluted white vinegar and warm water for approximately 2 hours; then,the thick stratum corneum was scraped off; and the skin lesions were disinfected with alcohol. For the cryotherapy,a freezing rod dipped in liquid nitrogen was placed directly on the surface of the plantar warts. The contact time was approximately 15 to 30 seconds to ensure that a 2 mm margin of normal skin around the plantar warts became white. In general,repeated freezing two to five times per session was needed,according to the size of the plantar warts,patient tolerance,and response to cryotherapy. After 2 weeks,the decision was made whether to continue treatment on the basis of the condition of the cryotherapy wound.","department":"
