The way to remove moles usually depends on the type, size and location of moles. Generally speaking, more than 3 mm must be removed.
1. If it is suspected to be malignant, it should be removed, and biopsy should be done, so the laser may not be clean. Compound nevus and dermal nevus are too deep and protruding. If they want to be cleared, they should be cleared. Larger nevus should be sutured after excision, and even skin grafting (transferring a piece of skin from other places) and skin flap transfer (taking the meat next to it) are needed.
2. Laser laser is a treatment method that converts electric energy into light, which is suitable for small and shallow moles, such as flat-seam moles.
3. High-frequency electrocautery destroys cells with heat energy.
4. Liquid nitrogen freezing is destroyed at the low temperature of-196 degrees Celsius, but it is rarely used.
5. The disadvantage of chemical cauterization is that it is difficult to control the depth and range of cauterization. When burned, there will be concave holes, some of which are deep, so the medical profession does not use this method, but some beauty salons and night market stalls in Dot mole like to use it.
Ou said that almost all moles can be removed, but if they are not handled properly, most will leave obvious scars. It is difficult to remove moles on eyelids and nose; Eyelids are difficult to sew, nasal nevus is difficult to repair, and skin grafting or skin flap transfer is needed; It is easier to do nevus removal surgery with decree lines because there are many surrounding tissues.
Precautions before and after operation
Do not use any maintenance or cosmetics before removing moles and laser surgery. These operations require anesthesia, laser surface anesthesia and injection anesthesia, both of which require informed consent. After laser surgery, we should do a good job of sun protection, and apply antibiotic ointment or artificial skin according to the doctor's advice before the wound scabs off to ensure the best effect. Apply beauty patch 3 ~ 6 months after stitches are removed.
Who should I ask for help?
Ou pointed out that nevus resection, laser, plastic surgery and dermatology can be done, and some patients go directly to plastic surgery.
Beirong Li Dingda suggested that for moles with malignant suspicion, you should see a dermatologist first, and you can judge them with the naked eye according to clinical data. If it can't be judged by the naked eye, a biopsy should be performed and interpreted by a dermatologist to determine whether it is malignant.
Dermatologists in big hospitals can do skin biopsy and interpret the results themselves. It is no problem to use laser to remove moles for cosmetic purposes. But large-scale excision, even skin grafting, or facial beauty and function are more suitable for reference plastic surgery. However, every hospital has it.
Ordinary people should pay attention to observe whether the moles on their bodies have changed. If they feel suspicious, they should see a doctor as soon as possible. Dr. Li said that people with moles can take photos of moles every once in a while, or take the photos to the hospital for doctors to see.
