The myofibroblasts are absent in the first trimester in the embryonic stage where damage heals scar-free; [19] in small incisional or excision wounds less than 2 mm that also heal without scarring; [19] and in adult unwounded tissues where the fibroblast in itself is arrested; however, the myofibroblast is found in massive numbers in adult ...

Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
Granulation tissue is composed of tissue matrix supporting a variety of cell types, [3] most of which can be associated with one of the following functions: formation of extracellular matrix; operation of the immune system; vascularisation; An excess of granulation tissue (caro luxurians) is informally referred to as "proud flesh".

Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reducing the course of treatment needed (and time in the hospital), and improving the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts:
for scraping or debriding biological tissue or debris in a biopsy, excision, or cleaning procedure Come in various sizes and shapes Dermatome: To take off a top layer of skin to implant over another area; Forceps, Dissecting: Grasping/holding. Usually used in skin closure or small wounds Adson: Forceps, Tissue: Grasping/holding tissue Allis

When removal of tissue is necessary for the treatment of wounds, hydrotherapy which performs selective mechanical debridement can be used. [8] Examples of this include directed wound irrigation and therapeutic irrigation with suction. [8]
