ABSTRACT
Filling substances for dermal atrophic changes and tissue augmentation consist of
various compounds: autologous fat, bovine and human collagen, hyaluronic acid
from avian or bacterial sources, and various synthetic substances, such as Gortex,
silicone, and plastic beads. Each of these compounds has advantages and disad-
vantages. We have found that excised varicose veins on the legs and other
unwanted veins (such as dorsal hand veins) are easy to procure and long lasting
if not permanent.
