Can my Existing Implant Behind the Muscle Be Left in with a Mastectomy?

First of all I'm sorry for you certain anxiety waiting for your results. Without knowing the specifics of you breast size and implant size I can't comment with confidence. Oridinarilly in this situation, the implant would be removed at the time of mastectomy along with the scar tissue (capsule) around the implant. The tricky part here is that the muscle is very thin and attenuated. As a result it is hard to use for the reconstruction. In most cases, I put in an expander at the time of mastectomy and replace it later with an implant. The advantage here is that I can put in the exact amount of fluid necessary to get the volume I need and the patient can have input as to their desired shape. I wish you the best!

While there are a number of individual factors to consider, it is generally not a good idea to have radiation therapy with breast implants so the mastectomy is often the best option. Often the mastectomy can be done with a skin-sparing technique, and the reconstruction done at the same time. The new implant would need to be larger to compensate for the breast tissue that was removed, and the use of Alloderm to support the implant is also routine, since the muscle only covers the upper portion of the implant.

In many instances the implant can remain in place for a lumpectomy.  If your require a mastectomy then you should see a plastic surgeon regrading your ability to have immediate single stage reconstruction using permanent silicone gel implants and alloderm or a two stage reconstruction using tissue expanders and alloderm.  If you decide you no longer want implants than consultation with a reconstructive surgeon regarding various flp options including the DIEP, TMP, and PAP flaps is helpful.  IN addition I also perform immediate breast reconstruction with fat graft alone.  This technique is newer and requires a conversation about the use of BRAVA after the initial reconstruction.
