Upcoming retraction surgery - should I be concerned about it failing? (photos)

Acelluar dermal matrix is human collagen from cadaveric skin. The cells have been removed and the tissue is irradiated to sterilize it. The problem is that the collagen is not your collagen. Over the course of a couple of months, your body will remove this material. It is replaced by your body with scar tissue. This is the basis for the contraction that occurs after surgery. The material is very convenient. It comes out of a package for no extra surgical time is needed for harvesting the material. In contrast, hard palate, the material I use as a lower eyelid spacer must be harvested. An acrylic stent must be fabricated by your dentist prior to surgery for the roof of the mouth. This is used to cover the harvest area after the graft is taken. However, this extra effort is worthwhile because the hard palate graft taken from the roof of the mouth does not disappear. It survives in it new location and provides help for a lifetime. I would also suggest that you would benefit from an orbital rim implant.
