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.

An increasingly common aid to both pre-operative wound maintenance and post-operative graft healing is the use of negative pressure wound therapy (NPWT). This system works by placing a section of foam cut to size over the wound, then laying a perforated tube onto the foam. The arrangement is then secured with bandages.
Full-thickness (FT) injuries cause dermal wound healing, which is characterized by maturation (contraction and increased tensile strength), proliferation (collagen synthesis leading to wound closure), and inflammation . FT wounds heal by excision and grafting, contracture, or epithelial ingrowths from the margins. [2]
A week after the injury, the edges of the wound are pulled together by contraction. Contraction is an important part of the healing process when damage has been extensive, and involves shrinking in size of underlying contractile connective tissue, which brings the wound margins toward one another.

Shave excision is the most frequently used method for mole removal. Anesthesia is first administered to the area around the mole. With the use of a sharp razor, multiple horizontal cuts are then made to remove the mole. This is followed by electrosurgical feathering, where a small dermal loop electrode is used to gently shape the edges of the ...
Healing of a wound begins with clot formation to stop bleeding and to reduce infection by bacteria, viruses and fungi. Clotting is followed by neutrophil invasion three to 24 hours after the wound has been incurred, with mitoses beginning in epithelial cells after 24 to 48 hours. [citation needed]
The wound usually appears red and can be accompanied by drainage. Clinicians delay re-opening the wound unless it is necessary due to the potential of other complications. If the surgical wound worsens, or if a rupture of the digestive system is suspected the decision may be to investigate the source of the drainage or infection. [2] [3]
