Laser Dot mole: Pigment tissue is crushed and decomposed by the huge energy of laser in an instant, and is swallowed by macrophages and excreted, thus achieving the purpose of removing pigment.
High-frequency electrocautery to remove moles: using the principle of electric heating and high-temperature cautery to remove moles caused by burning and carbonization.
2. The advantages and disadvantages are different.
Laser Dot mole:
Advantages: Laser nevus removal can control the best spot size and depth, and it is not easy to leave scars and infections.
Disadvantages: no shortcomings, accepted by most people, popular.
High-frequency electrocautery to remove moles;
Advantages: simple operation.
Disadvantages: it is difficult to control the degree of burning, leaving scars easily and unacceptable.
Extended data:
Other methods:
First, surgical resection
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.
Second, chemical corrosion.
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.
Third, the 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. Dermatology is not used for the treatment of moles because it is not easy to control the depth and often causes injuries.
Indications: Flat nevus with a diameter of 0.3-0.5 cm, including freckles.
