Chemical etching method

Indications: Nevus with light color and light position.

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.

Electric combustion method

Indications: nevus with a diameter of 0.3-0.5 cm.

Methods: The principle of electric heating and high temperature burning was used to remove the nevus caused by burning and carbonization.

Advantages: simple operation, some beauty salons may also be able to operate.

Disadvantages: it is difficult to control the degree of burning, and it is easy to leave scars.

freezing method

Indications: Flat nevus with a diameter of 0.3-0.5 cm, including freckles.

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 injury is easy to master, it can be cured at one time, and it is not easy to cause obvious scars.

Disadvantages: large and thick moles need to be frozen several times to be cured, and special instruments must be equipped, and the doctor's skills are also very important.

Laser method

Indications: Most of them can be used, including deep and shallow nevus.

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.

method of work

Indications: large and prominent nevus with a diameter greater than 0.6 cm.

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. Generally, this method is rarely used for moles.
