Third-degree burns destroy entire skin thickness including epidermis and dermis reaching subcutaneous tissue requiring extensive treatment. Appearance varies from white and waxy to charred black with leathery texture lacking sensation due to nerve destruction. These severe burns cannot heal independently requiring surgical debridement and skin grafting. Causes include prolonged flame exposure, immersion scalds, chemical burns, and electrical injuries. Immediate complications include fluid loss, infection risk, and systemic inflammatory response. Treatment requires specialized burn units with surgical expertise and intensive care capabilities. Multiple surgeries remove dead tissue and apply grafts from donor sites creating additional wounds. Healing takes months with extensive scarring, contractures, and functional limitations. Physical therapy prevents joint restrictions while occupational therapy addresses daily activities. Psychological trauma from disfigurement and painful treatment requires ongoing support. Infection remains the leading cause of death given loss of skin’s protective barrier. Hypertrophic scarring and keloids create both functional and aesthetic problems. Amputation may be necessary for circumferential burns compromising circulation. Legal damages reflect catastrophic impacts including lifetime medical needs and profound suffering. Understanding third-degree burn severity justifies maximum compensation for these life-altering injuries.
