Burn injury of second degree deep dermal and full thickness delays in healing and heals by scarring. Deep dermal burns need early treatment by tangential excision and skin grafting to promote healing. While wound irrigation, debridement, and local wound care may be sufficient for managing superficial burns (involving the epidermis and superficial dermal layer), deep burns (involving the deep dermal layer and other structures deeper to it) require tangential excision and skin grafting. If performed early it is associated with better outcomes in terms of reduced infection risk and hastened wound healing.
