Wound healing is the process by which skin or other body tissue repairs itself after trauma. In undamaged skin, the epidermis (surface layer) and dermis (deeper layer) form a protective barrier against the external environment. When the barrier is broken, an orchestrated cascade of biochemical events is set into motion to repair the damage. This process is divided into predictable phases: blood clotting (hemostasis), inflammation, tissue growth (proliferation) and tissue remodeling (maturation). Blood clotting may be considered to be part of the inflammation stage instead of a separate stage. Proliferation (growth of new tissue): In this phase of wound healing, angiogenesis, collagen deposition, granulation tissue formation, epithelialization, and wound contraction occur. In angiogenesis, vascular endothelial cells form new blood vessels. In fibroplasia and granulation tissue formation, fibroblasts grow and form a new, provisional extracellular matrix (ECM) by excreting collagen and fibronectin. Concurrently, re-epithelialization of the epidermis occurs, in which epithelial cells proliferate and 'crawl' atop the wound bed, providing cover for the new tissue. In wound contraction, myofibroblasts decrease the size of the wound by gripping the wound edges and contracting using a mechanism that resembles that in smooth muscle cells. When the cells' roles are close to complete, unneeded cells undergo apoptosis. Source: Wikipedia

MA This medical video contains graphic images that may not be suitable for all viewers. Viewer discretion is advised. This video demonstrates the home care of the medium size open surgical wound. The purpose is for education of the lay public to better care for an open surgical wound in the home environment. This video demonstrates how to treat granulation tissue that appears during the healing process after incision and drainage of torso abscesses. Questions that patients frequently ask about this treatment are answered.
Granulation tissue is new connective tissue and tiny blood vessels that form on the surfaces of a wound during the healing process. Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. This video is targeted to blind users.

I thought as its taking so long to heal i will video my recovery so people can see just how long an open wound takes to heal... 19 days post surgery.

When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response. Lesson by Sarthak Sinha, animation by Karrot Animation.
