Wounds may be classified according to their depth and whether underlying tissues are damaged. Partial-thickness wounds do not intrude through the dermis and can heal by regeneration; full-thickness wounds involve both the epidermis and dermis, and sometimes underlying tissues as well. They generally heal by scar formation. Wound classification by morphology is shown below:
|Type||Tissue Characteristics||Etiology||Prognosis for Healing|
|Partial thickness||Involves entire epidermis and portions of dermis.||Friction, pressure, small cuts, minor burns.||Heal within 10-18 days, epidermal element germinates and migrates up to the epithelial layer. Heals without significant scarring or functional impairment.|
|Deep partial thickness||Involves entire epidermis and almost entire dermis.||Friction, cuts, significant burns.||Healing within 20-35 days.|
|Full thickness||Involves epidermis and dermis; may extend into subcutaneous tissue. Sweat glands and hair follicles are destroyed.||Severe deep cuts, surgical incisions, most chronic wounds, and third-degree burns.||Heals by granulation, formation of new blood vessels, new biomaterial deposition, and new cells over many weeks. Scarring usually results.|
|Underlying tissue damage||Considered more extensive than full- thickness wounds. Involves subcutaneous tissue, muscle, fascia, bone, and other organs.||Surgery of organs, electrical burns and certain thermal burns, such as molten metal or severe scalding, massive traumatic injury, and untreated chronic damage.||May require debridement or removal of all necrotic tissue to expose viable bleeding tissue. Systemic antibiotic therapy and grafts/flap skin replacement.|
