Electric combustion method
Methods: The principle of electric heating and high temperature burning was used to remove the nevus caused by burning and carbonization.
Advantages: simple operation, which can be operated by some beauty salons.
Disadvantages: it is difficult to control the degree of burning, and it is easy to leave scars. Indications: nevus with a diameter of 0.3-0.5 cm.
Laser Dot mole method
Methods: At present, laser can be used to remove superficial nevus, such as ruby laser, chromium laser or dye laser. If it is a large and deep mole, it should be removed by carbon dioxide ultra-pulse laser.
Advantages: Laser nevus removal can control the best spot size and depth, and it is not easy to leave scars and infections.
Disadvantages: if the mole is too deep, you may still have to play several times. Indications: Most of them can be used, including deep and shallow nevus.
Surgical excision
Methods: The pathological tissues around the nevus were surgically removed.
Advantages: this method can choose to partially or completely remove the diseased tissue, and different treatment methods can be carried out according to the nature of hydatidiform mole.
Disadvantages: it is difficult and takes a lot of time. This method is rarely used in general moles.
Indications: large and prominent nevus with a diameter greater than 0.6 cm.
Chemical etching method
Methods: Generally speaking, 50% triazole carbonic acid solution or alkaline reagent, such as sodium hydroxide, is suitable for nevus.
Advantages: Triazole carbonic acid solution is not easy to burn the skin and cause scars; Alkaline solution is corrosive and may take effect soon.
Disadvantages: triazole carbonic acid solution acts slowly, and the deeper mole may be 10 times; Sodium hydroxide is not easy to control the corrosion depth, and it is easy to cause deep scars.
Indications: Nevus with light color and light position.
freezing method
Methods: Cryopreservation with liquid nitrogen, high-speed freezing of pigmented nevus tissue, formation of water sores around pigmented nevus cells, and then spontaneous shedding.
Advantages: The depth of the injury is relatively easy to master, usually once, and it is not easy to cause obvious scars.
Disadvantages: large and thick moles can only be taken out after repeated freezing, and special instruments must be equipped, and the doctor's skills are also very important.
Indications: Flat nevus with a diameter of 0.3-0.5 cm, including freckles.
