Brief Summary

Best method in management of facial burn scar

Detailed Description

The stages of wound healing:proceed in an organized way and follow four processes: hemostasis, inflammation, proliferation and maturation. Although the stages of wound healing are linear, wounds can progress backward or forward depending on internal and external patient conditions. The four stages of wound healing are:Hemostasis Phase Hemostasis is the process of the wound being closed by clotting. Hemostasis starts when blood leaks out of the body. Inflammatory Phase Inflammation is the second stage of wound healing and begins right after the injury when the injured blood vessels leak transudate (made of water, salt, and protein) causing localized swelling. Proliferative Phase The proliferative phase of wound healing is when the wound is rebuilt with new tissue made up of collagen and extracellular matrix. Maturation Phase Also called the remodeling stage of wound healing, the maturation phase is when collagen is remodeled from type III to type I and the wound fully closes.

Fat Injection In Facial burn scar:The effects of the lipofilling can be seen starting from 3 weeks after the procedure, in terms of better scar color, pliability, thickness, relief, itching, pain, scar vascularization and pigmentation. Indeed, autologous fat grafting makes the skin softer, more flexible and extensible; besides, the color seems similar to the surrounding unharmed skin.

Platelet Rich Plasma In Facial burn scar: Impaired wound-healing and a long treatment course in severe burns as well as secondary complications originating from uncovered wounds motivate research to accelerate the wound-healing process and speed up re-epithelialization in burn patients.

Arm && Interventions

Group	Intervention	Description
platelet rich plasma injection in post burn facial scar	fat injection in post burn facial scar	prp in subgroup allocation 1:1 Obtain WB by venipuncture in acid citrate dextrose (ACD) tubes Do not chill the blood at any time before or during platelet separation. Centrifuge the blood using a 'soft' spin. Transfer the supernatant plasma containing platelets into another sterile tube (without anticoagulant). Centrifuge tube at a higher speed (a hard spin) to obtain a platelet concentrate. The lower 1/3rd is PRP and upper 2/3rd is platelet-poor plasma (PPP). At the bottom of the tube, platelet pellets are formed. Remove PPP and suspend the platelet pellets in a minimum quantity of plasma (2-4 mL) by gently shaking the tube.

fat injection in post burn facial scar	fat injection in post burn facial scar	After aspiration of the fatty tissue, it is important that nonviable components of the aspirate, such as oil, blood, and local anesthetics are removed and, at the same time, the quality, integrity, and viability of the adipocytes and the inherent mesenchymal stem cells in the aspirate be maintained. Processing techniques are sedimentation , filtering and washing There is no consensus as to the optimal method of fat graft preparation.
