What is the burn degree classification that involves the epidermis and subcutaneous tissue?

The classification of burns is based on the layers of skin affected. A third-degree burn is characterized by the involvement of the epidermis and the entire dermis, extending into the subcutaneous tissue. This type of burn typically presents as a white, charred, or leathery appearance due to the destruction of nerve endings within the skin, which often results in a loss of sensation in the affected area.

In contrast, first-degree burns affect only the outer layer of skin (epidermis) and are characterized by redness and pain without blistering. Second-degree burns impact the epidermis and part of the dermis, resulting in blistering and swelling. Fourth-degree burns extend beyond the subcutaneous tissue, potentially affecting underlying structures such as muscles, tendons, and bones, and are much more severe than third-degree burns. Thus, the classification of a third-degree burn as involving both the epidermis and subcutaneous tissue is accurate and essential for understanding the severity and treatment required for such injuries.
