Reading Time: <1 minuteWhat is important in mole treatment is post-treatment care, more than the removal method. No matter how cleanly the mole is removed, if the care for the scar after mole removal is insufficient or inappropriate, there is a high risk of a scar remaining after removal. Whether it is removal by excision, carbon dioxide laser, or high-frequency vaporization, a scar will always be left after mole removal. Caring for this wound in the right way is an important factor that determines whether you will be satisfied with the final result of mole removal. I have seen advertisements that say "Clean mole removal with carbon dioxide laser!!" but is it true? It is a rather exaggerated expression to say that a laser can remove it cleanly. Selectively remove pigment cells and make them disappear. This is the ultimate secret to mole removal. A flat mole with pigment deep in the dermis, called a pigmented nevi, is more difficult to completely remove than a raised mole, and the recurrence rate is higher. Removing it with a carbon dioxide laser means applying heat intensively to the mole tissue and vaporizing the mole tissue with that heat energy. The components of moles can be considered to be the same as those of living organisms, so it is roughly assumed to be composed of 60% water and 40% protein. If heat is applied to this tissue, the skin that comes into contact with the heat will naturally become burned. If this burn is in the shallow part of the dermis, granulation will not occur, epithelialization will occur quickly, and it will heal with almost no scars. The important point of care after mole removal is how quickly this epithelialization will be promoted. The latest wound healing theory recommends moist wound healing care that does not dry out the wound. Of course, disinfecting the wound is contraindicated. It is better to wash the wound every day. At our hospital, after mole removal, we apply antibiotic ointment and then apply a medical wound dressing to the wound. Leave it in this state for three days. Assuming that epithelialization will progress, after three days, the wound dressing will be removed and the wound will be washed in the shower, and the wound dressing will be applied for another three days. This initial care is very important in the process of healing the wound. Unlike the face, scars on the back and upper limbs take much longer to heal after mole removal. In particular, the lower limbs take more than three times longer to heal and for the redness to disappear compared to the face. The wound healing process differs depending on the part of the body. Specialists have a good understanding of which parts of the body heal quickly and which parts heal slowly, and can provide guidance on how to care for them. https://www.sakae-clinic.com/wound/ Mole scar care is important because it is a scar specialist.

Reading Time: <1 minuteIn principle, the anesthetic used for mole removal is lidocaine hydrochloride, or xylocaine.　https://www.kegg.jp/medicus-bin/japic_med_product?id=00000332-003is used. We use xylocaine containing epinephrine, a vasoconstrictor. Epirenamine has the effect of constricting blood vessels during treatment to suppress bleeding and extending the effective time of xylocaine. Although medical school textbooks state that use on the tip of the nose and fingertips is contraindicated, there are currently no clinical problems. (It was thought that vasoconstriction could cause skin necrosis.) A 0.5% to 2.0% concentration is often used, but for mole removal, 0.5% is a sufficient concentration and there is no problem with use. We use xylocaine in our clinic, and as the name xylocaine hydrochloride lidocaine suggests, its pH is acidic 3.3 to 5.0. When injected into the body, especially into the dermis, the drug causes pain due to the difference in pH when it diffuses. For this reason, we mix an alkaline drug called Meylon to further lower the concentration and adjust the pH to about 7.3, which is as close to the body's pH as possible, and we make our own by adjusting the pH. In actual use, the pain during injection is much less than that of conventional xylocaine injections, reducing the burden on the patient. In addition, the needle used to inject is extremely thin, from 30G to 34G, which significantly reduces the pain. When removing multiple moles, an injection is required for each mole, so pain relief care for the patient during anesthesia is always necessary. Although the amount of anesthesia required for mole removal is small and easy, careful injection can relieve pain. At our clinic, we use extremely thin needles and a homemade xylocaine anesthetic with an adjusted pH level to remove moles.
