[The development of plastic surgery: retrospective view of 80 years of "Der Chirurg" (The Surgeon)]

The often groundbreaking developments of new methods in Plastic Surgery have been published in the journal "Der Chirurg" (The Surgeon) ever since its foundation in 1928, when it was established as a journal dealing with all aspects of surgery and containing many innovations and developments. Historically this is also reflected in the establishment of Plastic Surgery initially as a subspecialty and later on as a specialty within the German Society for Surgery. The interdisciplinary character of modern reconstructive and oncological concepts, not only with other specialties but also within various surgical specialties, raises further challenges and leads to new developments in reconstruction, which will definitely induce an increasing amount of knowledge to the advantage of our patients. Scientific and clinical advances over the last 80 years give rise to the hope that similar success will be attained for reconstruction of traumatic and oncological defects and malformations or disfigurations in the future. Consolidated findings from regenerative medicine and tissue engineering will enrich the daily practice of surgical reconstruction.

[Pathogenesis of chronic wounds]

Chronic, nonhealing wounds and their therapy are not only a medical problem but a severe economic one as well. Such wounds have a great effect on quality of life. Basic research has enhanced our understanding of the stimulation and inhibition of wound healing and provides the basis for introducing new and innovative treatment methods. This paper reviews the most relevant in- and extrinsic factors that disturb physiologic wound healing to result in chronic nonhealing wounds. In addition, molecular intervention modalities targeting various aspects of wound repair are demonstrated.

The difficulties in facial reconstruction derive from the unique character of the face and the availability of local matching tissues. Facial reconstructive surgery must aim at a functionally and aesthetically rehabilitated patient. The performance of facial plastic surgery requires an understanding and the application of many important principles. The aim of this paper is to review the critical factors to be considered in the management of surgical wounds by second-intention healing, primary closure, skin grafting, and repair with local or distant free flaps. The key concepts useful in flap choice and implementation are discussed. In addition, an overview of new developments in tissue engineering and gene therapy as they relate to facial plastic surgery is provided.
