Radio wave removal is considered the most effective and safe method of dealing with moles. After it there are no scars, scars or burns that affect the aesthetics of the skin. With the help of radio waves, it is allowed to remove only benign growths with a clear contour and structure.
In which cases it is necessary to remove moles, according to what principle does radiosurgical equipment work and how should skin be treated after the procedure?
What you need to know about nevi
Birthmark - pigment formation on human skin. It can occur anywhere on the body and is formed by exposure to ultraviolet rays, hormonal levels, or genetic predisposition. At birth, the baby’s skin is clear of pigmented lesions, they appear later and may appear / disappear throughout life. Yes, a nevus can disappear on its own. This is possible after a severe sunburn. The disappearance of a mole is also a precursor of a rare disease of vitiligo.
At the heart of each nevus contains cells, melanocytes. They stimulate the production of melanin - a high molecular weight pigment. Melanin is widely distributed in both plant and animal tissues. Moreover, the pigment is found even in the simplest organism. It is melanin that determines the color of skin, hair, human eyes, as well as the color of feathers, scales, cuticles of insects, fish and animals. The pigment not only affects the color, but also performs a protective function, absorbing ultraviolet radiation.
How is a nevus formed? First a small flat spot appears on the skin. Over time, it changes color, takes shape, and may increase in size. The location of the mole depends on the concentration and localization of melanocytes. If they are in the epidermis (upper skin layer), the nevus will be flat, if in the dermis (deep skin layer) it will rise above the surface.
Convex moles - one of the options for the norm. They should not be afraid or immediately removed if a nevus does not bring discomfort. The main thing is that education should have the same color, size and rounded shape throughout the entire life cycle.
Types of skin formations
All benign skin lesions are conditionally divided by color, size, shape and surface texture. The generally accepted classification includes only two types of moles - congenital and acquired. Congenital nevi are divided by size into: small (1.5 centimeters in diameter), medium (no more than 10 centimeters), large (more than 10 centimeters), gigantic.
Giant formations cover the entire anatomical region (for example, the face). Small moles are safe and extremely rarely reborn into malignant tumors. Owners of giant moles should be alert, because in 50% of cases they degenerate into melanoma. To protect yourself - regularly conduct a self-examination and consult a dermatologist. Acquired moles begin to form in childhood. It is at this time that the restructuring and development of the whole organism takes place.
Melanocyte cells rise from the deep layers of the skin to its surface - the epidermis, where they accumulate and provoke the growth of moles. The location, size and number of nevi is determined by genetic factors, way of life, the external environment. Acquired moles are classified by localization:
- epidermal (accumulation of pigment cells in the upper layers of the skin);
- intradermal (accumulations of melanocytes in the deeper layers of the skin or dermis);
- borderline (accumulation of melanocytes on the border of the upper and lower layers of the skin).
Features of radio wave surgery
Radio wave surgery is the safest and most effective method for removing benign skin lesions. It removes both flat moles and voluminous, protruding above the skin surface. After exposure, there are no thermal burns or scars on the body. Moreover, the intervention does not involve stitching, which facilitates care and recovery. The device itself is represented by a radio wave knife and the main unit through which you can adjust the parameters and control the operation of the knife.
What is the principle of radio wave technology? The knife receives a radio signal that causes evaporation of fluid from the surrounding tissue. It is due to evaporation that the epidermis layer is excised.
High-frequency waves are quickly absorbed by the intracellular fluid, which reduces the risk of damage to healthy cells. The frequency of the waves most often is 3.8-4 MHz. It is in this range that tissue damage is reduced to a minimum.
Radio wave surgery offers a unique non-contact incision method. A surgical instrument is not inserted under the patient’s skin, but the tissue is still affected and changes its structure. Excision is possible due to heat. It stands out at the time of penetration of high-frequency waves in the fabric. At the same time, the accumulation and burst of intracellular energy occurs, which heats and actually evaporates the affected cells.
During evaporation, the patient does not experience the agonizing contraction of muscles or the stimulation of nerve endings, which causes severe pain. However, doctors inject painkillers to make the procedure as comfortable as possible.
Radio wave surgery is contraindicated in malignant degeneration of nevus into melanoma, presence of a pacemaker and activation of inflammatory processes in the body.
Advantages of the method
The advantages of radio wave surgery include:
- making cuts of any depth and configuration not only on the skin, but also on the mucous membranes;
- removal of a nevus in one session;
- lack of purulent discharge, bleeding and suturing;
- sterilizing effect that minimizes infectious complications;
- shortened therapeutic and rehabilitation period;
- no scars, scars or thermal burns, which allows you to maintain the aesthetic appearance of the skin.
Preparation and conduct of the operation
Before any intervention, the patient must be diagnosed by a dermatologist or a dermato-oncologist. The specialist will conduct an external examination of the skin, make a diagnosis and select the most optimal method of removal.
If you suspect a malignant process, radiowave intervention will have to be abandoned - melanomas are excised only surgically.
Immediately before the intervention, an anesthetic is administered to the patient. This may be intravenous injection or applying a special cream on the surface of the skin. After some time, the doctor starts to work.
The radio wave knife is heated with an electric charge, brought to the mole and cut off with one clear movement. The process itself, taking into account pain relief, takes about 20 minutes. The excised nevus is sent for laboratory diagnostics, and the patient can return to the usual routine of life.
How to care for skin after
After radio wave surgery, no scars or scars remain, but temporary postoperative edema is formed. In most cases, it is insignificant and passes on its own after a few hours or days. The intensity of the edema depends on the health of the patient. For example, rehabilitation with an internal inflammatory process may take much longer.
If you feel excessive fatigue, pain, discomfort, or you are worried about your skin condition, immediately contact a dermatologist.
In general, the care of the affected area is very simple. The first 3-8 days (depending on the size and specificity of the mole) are forbidden to wet the wound. This does not negate general body hygiene and gentle cleansing around the postoperative site. From the pool and bath for some time also have to be abandoned.
Choose loose clothing made from natural fabrics that will cover the wound, but not injure it. Use medications, gels and ointments prescribed by a dermatologist for skin care according to the recipe and discard self-treatment so as not to impair the process.
After 7-14 days, you should make an appointment with a dermatologist. The doctor will evaluate the condition of the skin, the presence / absence of complications and the need for further therapy.
Radio wave removal of birthmarks - standard medical and cosmetological procedure. Great for removing nevi on the face or other sensitive areas of the body. After radio wave interference, there are no stitches, scars or visible marks. The only caveat - immediately after the procedure, swelling is formed, but it quickly disappears without additional effort. Before removing a mole, you should consult a dermatologist to evaluate its general condition and rule out contraindications. Use the benefits of modern medicine and be healthy.
