Cauterization of warts with liquid nitrogen. Features of the procedure and care after

After the human papillomavirus enters the body, any manifestations of this disease can make themselves felt only after a long period of time. Warts are neoplasms that occur on the skin and mucous membranes, precisely because of the effects of HPV on the body.

At the moment, there are a number of procedures for the rapid removal of such growths, their medical treatment, and you can also use folk remedies, which we will not talk about today to get rid of them. One of the most popular methods of getting rid of such neoplasms is the removal of a wart with liquid nitrogen and now we will understand all the intricacies of such an operation.

The essence of the method

The so-called cryodestruction of warts is the process of destruction of growth cells, through the influence on the neoplasm of extremely low temperatures. The main element used to carry out such operations is nitrogen. Everyone knows that it goes into a liquid state at a temperature of minus 196 degrees, and if it is higher, then nitrogen becomes gaseous. When a specialist treats a wart with such a cold substance, all the water in its cells quickly freezes, expands, and as a result, the cell simply dies. Freezing can be painful, so anesthesia is injected into patients.Freezing warts with liquid nitrogen

After the wart is completely frozen and removed, a scar remains on the body. The period of restoration of the skin itself is from several weeks to a month or more, it all depends on the number and size of the removed formation. The site of the operation requires care, until the moment of complete healing. Since cauterization of a wart with liquid nitrogen solves only the problem of the visual manifestation of the human papillomavirus, then in parallel with the operation itself, doctors often prescribe also medication.

The benefits of cryodestruction

I will introduce the fact that this is one of the most modern methods of removing warts, moreover, of various types, experts distinguish a considerable number of advantages that look like this:

  • The duration of the operation is only a few minutes, subject to the presence of small neoplasms;
  • The effectiveness of the treatment of warts in this way is about 90%;
  • No special preliminary preparation of patients is required;
  • After operations, the scars, although they remain, are not pronounced;
  • There is no possibility of bleeding;
  • Fairly reasonable price for the procedure.

Disadvantages of the method

All methods for removing warts have their drawbacks, and here is what distinguishes cryodestruction in this case:

  • It is not easy enough to control the depth of exposure to the affected area. Sometimes the roots of the wart remain intact, and in individual cases, the freeze turns out to be too deep and the tissue repair is delayed for a long time;
  • Pain after surgery. This is especially true when plantar warts are removed;
  • Careful care of the wound after surgery is required;
  • After removal of the wart, its additional examination is impossible.

Despite these disadvantages, this method is used quite often and is considered very effective.

Removing Warts With Nitrogen: How It Works

For this procedure, an elementary set of tools is used. A special stick made of wood, wound with cotton wool on the tip, is used. Doctors also use a cryoapplicator, although today in different clinics, you can find different devices that can be used to perform the operation. The process itself is performed as follows:

  • The patient is given an analgesic directly to the site of the operation, after which a pause of 10 minutes is taken so that the remedy works;
  • A small stick with a cotton swab is used as the main device, but some clinics use a cryoprobe, which emits nitrogen directly from the reservoir to the neoplasm;
  • Liquid nitrogen is stored in a special cylinder, and a constant temperature is maintained there to keep it in this form. A swab with a cotton swab is dipped in liquid and applied abruptly to the growth. By the way, the cotton swab used should be slightly larger than the wart;
  • The stick with nitrogen is kept on the growth for about 30 seconds, since it evaporates quickly enough. Depending on the size of the formation, the number of times a cotton swab is applied to it can vary greatly, and the strength of pressing the growth itself also varies;

Plantar Wart Removal Process

  • Almost immediately, the wart turns pale, but after a while its color completely changes to white. When the so-called “fluff” forms on the surface of the growth, which appears due to the influence of low temperature on the formation, the operation ends and the wart is considered removed. Further, the skin color at the place of removal will change, this area will begin to swell and gradually recover;
  • In the presence of neoplasms that have deeply penetrated the skin, and plantar warts are such, a doctor may prescribe several procedures that are carried out at regular intervals. Extremely neglected cases when a relapse of the disease occurs can be treated for 5-6 months, but this rarely happens.


After the procedure, a blister always appears on the site of the wart, which may be red. This puffiness resolves independently and any effect on it is unacceptable.

Postoperative period

After the burning of the warts with liquid nitrogen ends, the site of the operation turns red and begins to swell. In some cases, a blister appears in patients after a couple of hours, and some find it only the next day – this is the normal state of the affected area, it should swell in the lion's share of cases. There will be liquid inside it, it has a bloody color, and all this does not look very nice, however, you should not try to open it or pierce it.

The resorption of the blister will last about a week, and only after that a dry crust will appear on that spot, which will peel off. It, of course, also cannot be peeled off, the period of complete restoration of the skin will last about another 2 weeks, and then, at the place of the operation, there will still be a pink skin that needs to be taken care of.

How to care for a wound

Since the freezing of warts leads to the fact that the patient receives quite serious damage to the skin, care must be taken to the site of the operation carefully. After the blister appears, it must be protected from damage, punctures and any mechanical stresses in general. Even ordinary touches can negatively affect it, up to the formation of pus inside it and serious inflammatory processes.Protecting the remote growth with a bandage

Twice a day it is treated with a potassium permanganate solution, although salicylic alcohol (2%) can be used, and such procedures are performed exactly until it disappears and a crust appears. It is at the time of restoration of the skin that you should be very sensitive to personal hygiene, since in addition to infections that are easy to bring into the damaged area of ​​the skin, you can achieve a relapse of the disease. We highlight the main points that will need to be observed in the postoperative period:

  • Do not use plasters to protect the blister, because of this, it can burst or be damaged;
  • As a protective coating, you can use a bandage or gauze bandage, fixing it with a band-aid, but do not press it down hard;
  • The blister can be wetted, but only on condition that it is not damaged during showering;
  • With tangible pains emanating from the blister, you can take pain medication;
  • A wound formed after surgery should be treated only with the means prescribed by the doctor. Self-medication in this case is unacceptable;
  • It is necessary to systematically lubricate the damaged area with antiseptics.

If you notice any non-standard changes on the skin that the doctor did not talk about, then you should definitely contact him. Patients can be referred to a skin dispensary for re-examination and treatment. But it is worth noting that complications in patients arise in a very small percentage of cases.

Possible consequences

Cryo-freezing, as such, is a disastrous enough process for the skin. That is why patients can observe the effects of nitrogen on the body. Of the main unpleasant moments encountered after operations, experts distinguish:

  • If you immediately remove a large number of warts, regardless of whether it was a leg, arm, or any other part of the body, then the skin after the disappearance of the blister will flake strongly for a week, and sometimes more;
  • Often after healing, a black scar, or simply dark, may appear on the body, which changes color only a month after the operation;
  • If the patient does not properly care for the place of operation, then inflammation, suppuration, swelling are possible, in the first days of its appearance, the swelling can burst, heal for a very long time and cause pain. This blood blister needs to be protected the most tremulously;
  • In some cases, with very large accumulations of warts, or the presence of one with very deep roots, relapse of the disease is possible, but this already depends on how experienced the doctor is with the patient.

Operation cost

Of course, pricing will directly depend on the region of the operation, the clinic itself and the quantity, as well as the size, growths themselves. If we take into account the clinics of the capital, then the service for removing warts with liquid nitrogen will cost from 400 rubles and up to 1500 rubles, sometimes more. The price also affects the equipment used, the part of the body on which the neoplasm appeared and the depth of the skin lesion. In regions, prices may differ dramatically.

To whom such a procedure is contraindicated

Despite the fact that cryo freezing at first glance may seem like an excellent solution for absolutely all categories of patients, in fact it is not. There are a number of contraindications that will not make it possible for some patients to get rid of warts. Of the main groups of patients who do not fit the method of removing the growth of nitrogen, it is worth highlighting:

  • Such therapy is not suitable for pregnant women, and in some cases for adolescents;
  • During diseases such as the common cold and flu, removing warts with nitrogen burning is also not possible;
  • People with pressure problems (in this case, diathermocoagulation where current is used) may be suitable;
  • There are patients who have a personal nitrogen intolerance;
  • People with a variety of nervous disorders, including epilepsy;
  • In inflammatory processes in the area of ​​wart removal.

The process of removing warts with nitrogen is quite simple, but still you need to be aware that not all organisms can easily transfer this effect to the tissues. Depending on the state of health, the stage of development of the growth, as well as a number of other factors, doctors will make conclusions about whether this method is suitable in a particular case, or you should pay attention to other options, such as a laser or a radio wave knife to remove neoplasms.

Alternative options from the pharmacy

Of course, it is strongly discouraged to independently engage in the treatment of such neoplasms, however, for some, a pharmacy is the best, and even more affordable option. Of the alternative drugs that are similar in their actions to the cryodestruction method, only Cryopharm and Wartner Cryo can be distinguished, since they are the most popular today. With their help, you can burn out the growth, and such a home-made method for removing warts is quite common, but without consulting a doctor it is better not to do this.

There are frequent cases when mistakes are made at home, due to which patients are then forced to undergo even more complex and expensive treatment. Despite the fact that instructions are attached to each of the drugs, many are in a hurry to use the drug, allowing for a bunch of oversights. Cryo removal, if not cool, should be done by professionals, not amateurs.Cryopharma from warts

Reviews on the cryodestruction procedure

Many patients note that this method of removing warts is effective, but still quite painful, and the recovery is long and requires a lot of attention to oneself. Cauterization of growths with nitrogen occurs in various clinics and conditions, so you can find the following reviews from those who went through this procedure:


“I had a wart on my foot. Since the foot began to bring a lot of inconvenience due to perceptible pain, I went to the hospital to remove it. At the beginning of the operation, the pain did not show much, but over time it became stronger. By morning, as after a burn, a bubble had formed on the leg, the doctor explained how and how to treat it. On about the 4th day, he burst, and only a week and a half later a crust appeared on that spot. At the moment, 1.5 months after the operation, a trail of light color remained on the site of the former wart. ”


“I got a few small warts that did not cause much discomfort, but still spoiled my appearance. I consulted with a doctor and I was prescribed a procedure for removing warts with nitrogen. Since the growths were small, they were removed at a time. Each of them was treated for less than 10 seconds, as a result, they turned red, dried out and eventually disappeared. The pain was not strong, but most likely due to their small size, now there are subtle spots in that place. "


“There were several warts, large enough, on the arm. I deleted them in a good clinic, but, nevertheless, the pain was. The operation was quick enough, after a few hours a bubble began to form in that place, but the doctor immediately warned about this. To treat the wounds, I was prescribed a solution, and medications were prescribed as additional therapy. I was pleased with the treatment, the traces after the operation are almost imperceptible. ”


After the warts began to appear, do not postpone the trip to the doctor in a long box. The solution to the problem is quite simple, because cryotherapy is a reliable way to remove growths. After the operation, you just need to monitor the place of its conduct, lubricate the wound, prevent its damage and then there will be no trace of warts.
