What biologic (e.g. porcine xenografts) or alternative dressings have you found helpful for second-intention wound healing?

Over the last 6 years, I have utilized a number of allograft/xenograft options for select wounds where linear/flap closure is not ideal and an FTSG/STSG/Burow's Graft is not preferred.

They range from Animal derived Collagens, Placental, and Amniotic products, and Cadaver skin grafts (i.e. Theraskin).

Derm surgeons/Mohs surgeons may frequently be approached by representatives promoting often costly products, and many of the products are definitely valuable with a proven history of improving second intention healing/depth of scars.

For the past several months, I have been utilizing Puracol Plus Collagen sheets, and have found them very useful as well as affordable. The cost impact on patients is negligible in regard to product cost.

I am using the Oasis Ultra Tri-layer matrix by Smith&Nephew - prefer the previous EZ derm porcine xenograft but this still seems to work for large, deep wounds (particularly on the scalp).
