Cryotherapy

Cryotherapy (cryosurgery) is a safe way to treat diseased tissues in both humans and furry companions. Although it is sometimes referred to as cryosurgery, it does not involve any cutting. This technique uses freezing temperatures to target abnormal cells which also numbs the sensory nerves surrounding the area.

What can be treated with cryotherapy?

Cryotherapy is often used to treat various diseases and disorders, especially those of the skin. In animals, this technique is used to treat tumours, warts or skin tags on the eyelids, chin, mouth, nose and ears. It can also be used to treat lesions that occur from scratching, licking etc and to kill bacteria and germs. Many of these conditions can be cured with just one session of cryotherapy.

How is it performed?

Cryotherapy uses freezing temperatures to target dangerous cell tissues. Water makes up about 70% of your loyal companion’s body which is what makes cryotherapy successful. Supercooled liquid nitrogen is sprayed (with a cryoprobe) or dabbed onto diseased tissues with a foam or cotton swab. The procedure can also be performed using an ultra-thin cryoneedle, which gives the veterinarian more control over the amount of tissues that are impacted. By adding freezing temperatures to the cells, they begin to crystallize from the inside which makes them tear and rupture. The blood vessels at the targeted area also temporarily freeze which adds further damage to those cells and tissues.

Is cryotherapy painful?

From experiencing tough Canadian winters, we know that freezing can be painful. For this reason, anesthesia is always used with this technique. The veterinarian will either use local or general anesthesia. The tissues slowly die and freezing provides a temporary anesthetic effect on the nerve endings. For some moist areas, the tissues may turn into liquid and have a green colour. Despite this, your loyal companion will not feel any pain. After the treatment, the patient may have some hair loss at the site and within 14 days a scab will form on the area.
