Liquid nitrogen cryotherapy for warts

Warts are a relatively serious skin disease. Patients with warts will have spots and scars on their skin, and many patients will also have redness, swelling and itching on their skin, causing great pain to patients. Moreover, warts are a disease that is very prone to recurrence. Currently, the medical treatment of warts generally uses liquid nitrogen freezing method. So, how does liquid nitrogen freezing treat warts?

1. What is liquid nitrogen cryotherapy?

Liquid nitrogen cryotherapy refers to a new technology in the field of modern therapeutics. It can kill viruses through extremely rapid freezing. People with severe cold urticaria cannot use this method for treatment. Liquid nitrogen cryotherapy is a comprehensive effect of cryobiology. Normal cells will suffer irreversible damage when they are in an extremely frozen state. It works by rapidly killing the cells in the diseased area in an extremely frozen state, allowing the diseased area to recover normally. It is generally used to treat warts, corns, verrucae, neurodermatitis and skin diseases.

2. Indications

Flat warts, molluscum contagiosum, keloids, chronic eczema, neurodermatitis, corns, lichen planus, prurigo, seborrheic dermatitis, etc.

3. Contraindications

Severe cold urticaria, cryoglobulinemia, Raynaud's disease, and a small number of elderly, weak, and those who cannot tolerate cryotherapy. Patients with diabetes and lower limb blood circulation disorders often develop chronic ulcers that do not heal for a long time if they undergo cryotherapy on their calves and feet. Cryotherapy should be used with caution.

IV. Precautions

1. After cryotherapy, the wound surface should be kept clean and dry, and should not be exposed to water within one week. Apply antibiotic ointment daily to prevent infection. Allow the scab to fall off naturally; do not scratch, tear, or scrub it with your hands.

2. After treatment, local tissue pain may occur, which will disappear on its own after 1-2 days. Painkillers can be taken if necessary.

3. If local tissues become swollen, have blisters or bullae after treatment, and there is too much blister fluid, you can use a sterile syringe to draw it out or puncture it, but do not tear off the blister wall. It is more obvious in areas with loose tissue, such as around the eye sockets or with tender skin.

4. If the lesion is not healed after one treatment and needs to be repeated, wait until the scab falls off by itself before repeating the treatment.

5. Generally, after cryotherapy, there is depigmentation in the center of the lesion and pigmentation around it. Especially after receiving cryotherapy on the face, you should pay attention to shading and sun protection to avoid aggravating local pigmentation.

6. If there are blood vessels or the frozen area is too deep, some patients may experience delayed edema, exudation, blood blisters, bleeding, chronic ulcers, hypertrophic scars, non-healing of the wound surface, etc., and active symptomatic treatment should be given early. Facial treatment

Special attention should be paid.

7. Some patients may experience local neurological dysfunction, such as skin numbness and pain, which generally recover gradually within 3-6 months.
