Role of Nail Filer Assisted Dermabrasion in Scald Burns
Abstract: Deep second-degree and full-thickness burns tend to heal slowly and often result in scarring. To encourage proper healing, deep dermal burns need to be treated early with tangential excision and skin grafting. While superficial burns, which affect only the epidermis and upper dermal layers, can often be managed with wound irrigation, debridement, and basic wound care, deeper burns that extend into the lower dermal layers and beyond typically require more …
