Implants Under the Muscle or Over the Muscle After a Double Mastectomy?

I’m having a double mastectomy due to breast cancer. What are the advantages and disadvantages of placing an implant above the muscle and under the muscle? My surgeon didn’t really explain this well.

 Just like every procedure, there are advantages and this advantages to each technique. Going above the muscle gives the advantage of having less discomfort with surgery and also it eluminary’s any movement of the implant with contraction of your chest muscles... the so-called animation deformity.  The disadvantage is that it usually requires additional procedures of fat grafting to help give a more natural look to the reconstruction.
