The term cryosurgery refers to the use of cold and the decrease in temperature of a certain region of the body to treat a disease or symptom. Also known as “cold therapy”, cryosurgery covers a set of techniques used by various medical specialties, to reduce swelling, treat edema, relieve pain and inflammation, among other purposes. The process of “cooling” the fabric to be treated can be done in different ways: immersion in ice water, ice pack or bandages.

In Dermatology, cutaneous cryosurgery uses liquid nitrogen. Liquid nitrogen at -196 ° C causes skin lesions to freeze and reduces their temperature to well below zero, leading to the destruction of diseased tissue. In general, the application is done in two ways: by means of a spray that sprays a jet of liquid nitrogen directly on the lesion or by freezing tips close to the area to be treated.

Cryosurgery is an appropriate therapeutic option to treat benign, pre-malignant or malignant skin tumors, small, medium or large skin lesions, skin blemishes, wart removal, molluscum contagiosum, seborrheic keratosis, hemangioma, actinic keratosis, Bowen’s disease ( red, scaly or crusted plaque, not elevated and progressive) and basal cell carcinoma.

It is also an alternative for those who cannot do a treatment with the use of an electric scalpel, as well as for the elderly or people with panic to undergo surgery. It is also an option for treatments that use caustics, curettage, electrocoagulation and surgery.
