WHAT IS CRYOTHERAPY

Cryotherapy involves freezing a wart using a very cold substance (usually liquid nitrogen). Cryotherapy is a standard treatment for warts and can be done in our facility. The liquid nitrogen application usually takes less than a minute.

– Our specialist may trim the wart with a small knife before applying liquid nitrogen.
– Cryotherapy is painful. A numbing local anesthetic is usually not needed but may be used in some cases.
– Our specialist applies the liquid nitrogen to the wart using a probe or a cotton swab. Liquid nitrogen can also be sprayed directly on the wart.

Most warts require 1 to 4 treatments, with 1 to 3 weeks between each treatment.

Cryotherapy can also be done at home using an over-the-counter product such as Compound W Freeze Off. These home cryotherapy kits use a mixture of dimethyl ether and propane rather than liquid nitrogen. This mixture is used to soak a foam applicator that is then applied to the wart. This product may be safe for warts on the hands or feet but not for genital warts. Follow all instructions carefully to avoid serious burns and permanent scarring.

WHAT TO EXPECT AFTER SURGERY

Pain from cryotherapy can last up to 3 days. Healing is generally quick (7 to 14 days) with little or no scarring.

Within hours after treatment, a blister may form.
– If the blister breaks, clean the area to prevent the spread of the wart virus. Avoid contact with the fluid, which may contain the wart virus.
– The blister will dry up over the next few days, and the wart may fall off.

Multiple treatments may be needed to get rid of the wart.

WHY IT IS DONE

Cryotherapy is usually used if salicylic acid treatment has not eliminated a wart or if quick treatment is desired.

HOW WELL IT WORKS?
Cryotherapy can destroy warts. It gets rid of warts about half of the time, but two or more treatments may be needed.
RISKS
If done carefully, cryotherapy poses little risk of scarring.
