Augustus V. Waller and plastic surgery.

Augustus V. Waller's name is associated eponymously with the regressive changes in transected nerves. This article intends to present the many other aspects of Waller's scientific ventures. Apart from pioneering intravital microscopy, Waller made significant contributions to the understanding of the process of tissue inflammation. In addition to his observations of the degenerative changes in severed nerve fibers, he developed a concept of trophic dependence that is relevant for the management of the regeneration of peripheral nerves in plastic surgery.
