Cryosurgery, also known as cryotherapy, is a non-invasive treatment that uses extreme cold to eliminate abnormal tissue such as warts and lesions. Unlike traditional surgery, there is no cutting involved. This user-friendly technique has been used for centuries in human medicine and is now commonly employed in veterinary practice.
During Cryosurgery, a specialised instrument emits a fine jet of extremely cold liquid nitrogen onto the targeted tissue. The precision of the device minimises damage to healthy surrounding tissue. The freezing process is quick, typically taking only a few seconds. After freezing, the tissue is allowed to thaw before repeating the freezing process.
Cryosurgery is generally not considered painful, although some animals may feel slight discomfort initially. If the lesion is in a sensitive or delicate area, such as around the eyes, a sedative may be administered. To ensure your pet's comfort, a pain-relief injection may also be given before they are sent home.
After Cryosurgery, you may notice that the treated area appears inflamed and slightly larger than before treatment. A scab will form, followed by a crust, which should naturally fall off within 10-14 days without requiring further intervention. To prevent irritation, it's important to ensure your pet cannot disturb the area during this time. Depending on the lesion's location, we may recommend using a buster collar or a pet t-shirt. We kindly request that you send us a progress photo once the crust has fallen off, along with an update on your pet's well-being. If you have any concerns about the process, we will gladly arrange an examination for your animal.
In rare cases, a second treatment may be necessary. It is recommended to schedule the second treatment within four weeks of the initial therapy. Second treatments typically cause less discomfort since the sensory nerves have already been desensitised. Often, even if the first treatment was performed under sedation, pets will tolerate the second session while conscious.
