Which burn depth is most likely to require grafting for proper healing?

• A. Superficial burn.
• B. Full-thickness burn.
• C. Partial-thickness burn.
• D. Subdermal burn.

Answer: (B)

Burn depth dictates whether healing can occur on its own or needs surgical closure. A full-thickness burn destroys both the epidermis and the dermis, including the skin’s regenerative structures like hair follicles and sweat glands. With those regenerative components gone, there are no viable cells to re-epithelialize the wound, so spontaneous healing is not possible. The damaged skin also loses its barrier function, making infection risk and fluid loss a major concern. To restore the skin’s barrier and function, a graft is needed—transplanting healthy skin to the wound site provides a new epidermal-dermal surface that can heal properly and restore form and function. That’s why full-thickness burns are the ones most likely to require grafting for proper healing. Superficial burns heal readily from remaining epidermal cells, and deep partial-thickness burns may heal or still improve with time, sometimes avoiding grafts if they re-epithelialize; subdermal burns are extremely deep and typically require surgical intervention as well, but the deepest category is the most consistently grafted for reliable closure.
