Abstract
The present paper reports the central role of fibrin (and specifically its pre-stage, fibrinogen), thrombin and coagulation factor XIII in wound healing and scar formation. The significance of these three factors has led to the development of a tissue adhesion system on a physiological basis, which can be applied in widely varying areas of surgery. The adhesive allows the exact, flat adaptation of the wound edges and thus promotes flawless scar formation. Two case reports complete the exposition.
