Cryosurgery is a method for painless and bloodless destruction of pathological tissues using, for example, liquid nitrogen. Specialized treatment equipment allows you to obtain a temperature of approx. -195°C. The procedure is painless and usually consists of triple freezing of skin lesions, with thawing in the meantime. During treatment, the patient may experience burning sensation, and after the treatment a rapidly subsiding mild pain or itching. In this case, destruction of the pathological lesions is delayed.
Within a few days of the cryosurgical treatment, a blister or a small wound may appear, which quickly heals. Sometimes (especially in the case of changes caused by virus), the treatment must be repeated several times.
In Dermatology, most commonly treated cryosurgically skin lesions are:
hypertrophy of the sebaceous glands
selected cases of Basal Cell Carcinoma (BCC)
