DARIAS DOMINGUEZ, Cristy; ROQUE ENRIQUEZ, Anabel; TORRES CARRASCAL, Carlos Andrés    OLIVA PEREZ, Yosiel. Therapeutic effects of cryotherapy with liquid nitrogen in lesions by photo damage in dermatologic consultation. []. , 43, 4, pp. 1069-1078.   31--2021. ISSN 1684-1824.

Cryotherapy is the whole of procedures that use cold in medical therapy. It uses various systems and results in a decrease in skin temperature, leading to a local destruction of tissue in an effective and controlled way. The objective of this work is to make an update to expose the essential aspects on the ways of use, indications, complications and contraindications. There are several cryotherapy application methods that include spray or spray freezing techniques and applicators, the cryoprobe method, and the thermocoupler use. It is indicated in several entities, and among the most frequent are seborrheic and actinic keratosis, solar lentigo, basal cell and squamous cell carcinomas in situ. The most observed complications are vesical blisters, hyperpigmentation and hypopigmentation, and the most common complications are: cold intolerance, tumors with non-delimited borders or very dark pigmentation, located near the margins of the eyes, on eyelids, mucous membranes, nasal wings, and on the ear canal. The mastery of the signs and application methods are essential to choose the appropriate behavior against the disease: side effects and complications are avoided that way.
