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]
Cryotherapy, using liquid nitrogen, can be used by a dermatologist to destroy the milia, “which may cause it to form a blister or a scab and then subside,” Dr. Garshick explains.
Cryosurgery is used to treat a number of diseases and disorders, most especially skin conditions like warts, moles, skin tags and solar keratoses. 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 ...
Cryomassage is a type of massage involving the application of superficial cold to body tissue, [1] typically using ice or liquid nitrogen. [2] As a cryotherapy technique, cryomassage has been used to treat physical injury, [3] skin disorders [1] such as rosacea and facial erythrosis (redness), [2] and facial nerve neuropathy.
Medical cryotherapy gun with liquid nitrogen. In medical applications, spray cans containing dimethyl ether [4] or tetrafluoroethane may also be used to freeze and destroy tissue, for removal of warts and skin tags, or other uses in cryosurgery. Liquified petroleum gas including propane and butane is sometimes used.
The use in prostate and renal cryoablation are the most common. Although sometimes applied in cryosurgery through laparoscopic or open surgical approaches, most often cryoablation is performed percutaneously (through the skin and into the target tissue containing the tumor) by a medical specialist, such as an interventional radiologist.
Liquid nitrogen (−195.8 °C) is the most commonly used destructive therapy for the treatment of AK in the United States. [72] It is a well-tolerated office procedure that does not require anesthesia. [73] Cryotherapy is particularly indicated for cases where there are fewer than 15 thin, well-demarcated lesions. [72]
"Liquid nitrogen cryosurgery with a cryogun is the coldest (-196º C), most effective, and most versatile cryosurgical technique available. Using liquid nitrogen equipment like a cryogun is much colder and therefore more effective than applying LN2 with a swab (-20º C), nitrous oxide (-75º C), and disposable cold sprays (-55º C to -70º C).
