Extreme cold used to treat benign skin lesions such as skin tags, warts and cysts — usually while your pet is awake, with no stitches and no cone collar.
Cryotherapy is the use of extreme cold — liquid nitrogen or nitrous oxide — to treat benign skin lesions such as skin tags, warts and cysts, and other dermatologic conditions of the skin and ears. At VetDERM Clinic we use a pressurized instrument called a Cryoprobe, which uses nitrous oxide.
Dogs and cats may develop a range of skin lesions with variable side effects including itchiness, irritation, discharge, crusting and infection. These lesions can be annoying for the pet, so removal is regularly advised. Surgery using a scalpel has been the conventional treatment for many years, but it more often than not requires sedation or anesthesia. Depending on the age of the pet or concurrent health conditions, sedation may not be the preferred choice and can add significantly to the cost.
Cryotherapy causes minimal to mild discomfort and can usually be performed while your pet is awake, with freezing agents or mild sedation if necessary. There is typically no bleeding, and in most cases no stitches or cone collars are needed afterwards.

What cryotherapy can treat
Further testing before treatment — a fine needle aspirate or biopsy — may be indicated and will be planned if necessary, depending on individual patient needs.
Sebaceous adenomas
Viral warts (papillomas)
Histiocytomas
Epidermal and follicular cysts
Meibomian gland adenomas
Eosinophilic granuloma complex (cats)
Acral lick granulomas
What to expect
The honest version.
Redness of the treated area occurs within a few days, after which the area will scab over and eventually fall off. Up to four treatments spaced two to four weeks apart may be needed to fully treat the affected area. Cryotherapy is not appropriate for all patients.
Some effects can be:
Skin pigment changes
Hair colour changes or hair loss at the treated area
Sensory impairment
Scarring
Infection
