With advances in the knowledge of wound healing, as well as the development of better materials and techniques, many options have become available in the treatment of patients with unsightly scars. Nevertheless, no technique has been devised to allow total and permanent removal or effacement of scars. Patients should be counseled to understand that the goal of scar revision is to replace one scar for another to improve the appearance and the acceptability of the scar.
The wound healing process is divided into three stages. In the inflammatory phase, the release of inflammatory mediators results in migration of fibroblasts into the wound. During the proliferative phase, an extracellular matrix is formed that is comprised of proteoglycans, fibronectin, hyaluronic acid, and collagen secreted by fibroblasts. Angiogenesis and re-epithelialization of the wound also occur during the proliferative phase. Collagen and the extracellular matrix mature in the remodeling phase, and the wound contracts. Wound strength reaches 20% of its pre-injury strength at three weeks. The ultimate tensile strength of the wound is 70–80% of that of the uninjured skin.
