Difference between Alloderm and Strattice?

Alloderm is human skin and hence is defined as an allograft.  Xenografts are grafts from non humans such as the pig (porcine).  Strattice is a porcine graft and hence is a xenograft.  Both work in the human because of the processing by the company which removes antigens that cause rejection.  Both are well accepted in human surgery and have many millions of uses in man.  The choice in using them is related often to the surgeons preference.  Alloderm is softer and easier to sew through.  Strattice is typically thicker and tougher and sometimes preferable because of the thickness and strength it provides.  

Your surgeon has the capability to perform the bottom out support procedure with several acellular dermal matrix products (ADMs). You can have a procedure that respects your wishes and allows a successful procedure.
The Strattice is porcine or pig skin acellular dermal matrix. It has no antigenicity, and has been shown to have almost no immune response. Strattice is substantially cheaper and has somewhat higher tensile strength. But in a bottom out surgery, the thick or extra thick Alloderm pieces can provide the appropriate reinforcement of your stretched out fold.  
I know the technical profiles of a host of other dermal matrix products, but none that have the science and process specifics of Alloderm. Alloderm safety profile is the most studied. All other products compare themselves to Alloderm in one way or another.

many surgeons use adm for a variety of problems including the one you are having.  non-porcine adms are available and if this is your preference, it should not alter your final result.  

The main difference between these two products as you have already noted is in the origin: porcine vs. human cadaveric. They are both produced by the same manufacturers and work in a similar fashion. The primary reason Strattic has become the go-to product for revisionary cosmetic procedures is that of cost. Strattice is less costly than Alloderm. In the comsetic setting, where insurance is not involved and the patient bears the brunt of cost, Strattice is the more economical choice.Ultimately, both are safe and effective options for the treatment of "bottoming out." If the idea of using a product of porcine origin is of concern there are a number of other ADM options available from other manufacturers which may offer some cost savings over Alloderm. Alternatively, you could choose to pay for the additional cost of Alloderm.As always, discuss your concerns with a board certified plastic surgeon.

Both Strattice and Alloderm are great products. The strattice is a little more firm but sometimes that is desirable in trying to maintain the position of the implant and revise a pocket. I use it in the cosmetic setting for what you are describing b/c of its strength and b/c it is less expensive. In the process of treating the pig skin all protein is removed so that your body doesn't "reject" it. Basically it is a sterile scaffolding or matrix that your body infiltrates with your own blood vessels and building blocks. That said, if your more comfortable with Alloderm then I would use that. Best of Luck!

Alloderm is derived from human cadaver skin, it has been processed to be acellular and therefore the recipient immune system doesn't reject it. The only problem I have seen with it when, it is used for cosmetic breast implant surgery, is the thickness of the alloderm is variable and doesn't seem to give much support.
Strattice is derived from pig skin and is also processed to be acellular and the immune system doesn't reject it. The advantage is the thickness of the tissue is consistent and, like alloderm, the body's blood vessels and collagen will grow into the tissue. Therefore reinforcing the support of the breast implant. This will diminish the risk of "bottoming out" and diminishes capsule contracture risks.
The Acellular status of the implant doesn't have the human nor porcine proteins. Therefore you, basically don't have a rejection risk with either tissues.

Hi! Thank you for the question. Strattice and Alloderm are both produced by the same company. One difference between them is in their origin: porcine vs. human. Strattice is derived from pigs but just as Alloderm, after processing it becomes acellular and your body doesn't reject it. They can both be use to correct bottoming out but Sttratice is significantly cheaper. Therefore it has become the go to product for some cosmetic procedures that require revisions.  I hope this helps and best of luck!

Even though these products may seem similar on the surface, they behave differently in real life.Specifically, alloderm tends to stretch with time.  Strattice does not.  When using the product to help 'hold' an internal suture repair to correct bottoming out, it may not be the ideal scenario to use a product that will stretch over time.

Strattice may be derived from pigs, but after processing there is no living tissue remaining. It becomes a collagen matrix and your body does not identify it as foreign material. The reason it is preferred in your situation is that it doesn't stretch so your bottoming-out is less likely to come back. 
My grandmother required heart valve replacements and for religious reasons, was reluctant to have pig valves inserted in her heart. However, it was the best thing for her medically at the time so she did it. I don't know what your reasons are for preferring Alloderm, but sometimes there are good reasons other than cost for medical decision making.

Thanks for an excellent question.
Both Alloderm and Strattice are soft tissue support devices or meshes. 
Alloderm is derived human dermis and is more elastic.  It is therefore suitable for areas where more stretch is desired -- such as the breasts and tissue expanders.  It is believed to reduce the incidence of capsular contracture.
Strattice is derived from porcine skin and is engineered to have less "give" than Alloderm.  Strattice is preferred for repairing hernias.  It has gained more traction in breast surgery due to it's lower cost and the fact that it is sterile (Alloderm is not sterile).  Because it is priced lower than Alloderm, many surgeons recommend Strattice over Alloderm for cosmetic procedures.
I hope this answer helps and I would recommend a thorough discussion with a Board Certified Plastic Surgeon for further explanations on ADMs.
