Please explain what a Dermal Matrix is and what is it made of?
Acellular dermal matrices (ADMs) are materials used in reconstructive as well as aesthetic surgeries. They are made up of either human cadaver dermis or animal dermis (most often the pig). The dermis is the deep layer of skin. These sheets of dermis have been processed so all of the cellular components have been removed. It is often used in breast reconstruction to provide an internal sling for the tissue expander or implant. The patient's body does not mount a significant inflammatory reaction against these implanted tissues because there are no cells within them to be deemed as "foreign." These ADMs act as a trellis or scaffold for the new breast construct. There are risks with these materials, however. They include infection, scarring, fluid build up, and rippling. When an ADM is used, a drain is necessary to remove any fluid that may occur in the pocket. Your plastic surgeon will be the one to remove that drain, usually about 1-3 weeks after the procedure. ADMs are an excellent adjunct in breast reconstruction and have helped plastic surgeons achieve more lasting results. They are also used in revisionary surgery.Hope this helps. Good luck!
