Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg -1 ⋅K -1 and heat of vaporization of 200 kJ⋅kg -1 makes it extremely useful in a wide range of applications ...
Cryoneurolysis differs from cryoablation in that cryoablation treatments use liquid nitrogen (boiling point of −195.8 °C) as the coolant, and therefore, fall into the range of a neurotmesis injury, or 3rd degree injury according to the Sunderland classification. Treatments of the nerve in this temperature range are irreversible.
The liquid nitrogen can also be sprayed onto the lesion using a spray canister. The spray canister may utilize a variety of nozzles for different spray patterns. [3] A cryoprobe, which is a metal applicator that has been cooled using liquid nitrogen, can also be directly applied onto lesions. [3]
Soon, the tall cryotherapy tank is filling with a cloud of super-chilled gas: evaporated liquid nitrogen, one of the coldest substances on Earth. “Okay,” the technician says. “Get in.”

Liquid nitrogen is usually used to freeze the tissues at the cellular level. The procedure is used often as it is relatively easy and quick, can be done in the doctor's office, and is deemed quite low risk. If a cancerous lesion is suspected then excision rather than cryosurgery may be deemed more appropriate. [14]
