[Scars and scar revision].

According to Clodius the scar is the surgeon's best advertisement. However, the development and formation of a scar does not always depend solely on surgical technique. The type and site of traumatic wounds, disordered wound healing and a keloid tendency are all factors which may lead to an unsatisfactory scar, requiring later revision. The basic principles of scar correction and various operative techniques are described in the present paper: 1. Linear operation techniques: Scar excision, W-plasty, VY-plasty, Broken line technique. 2. Regional flaps: Z-plasty, rhomboid flap. 3. Free grafts. Finally the basic principles of dermabrasion are presented. In addition the problem of keloid-formation, its prophylaxis and therapy are discussed.
