Nitrogen is a cryogenic agent used to treat various benign and malignant skin lesions.
In cryotherapy, mechanism of action could be classified into three stages: 1. heat transfer, 2. cell injury and 3. inflammation. Boiling point of liquid nitrogen is -196°C, which is the responsible for creating the initial stage which is heat transfer. The second stage is cell injury which is induced during thawing conditions of the cells. The last step in the cryotherapy is the inflammation stage which is characterized by edema and erythema. Inflammation occurs as a result of cellular death and it helps in local cell destruction.
Liquid nitrogen is used mainly as a cryogenic agent for the treatment of various benign and malignant skin lesions.
