I think the implant over the muscle sounds a lot less complicated, way back when I had mine done, it wasn't an option.
Coping with your appearance is a complex issue. I don't like anything about my retreads, but I could forgive them if I could only ignore them. Yes, the result is disappointing but that is, quite literally, not what keeps me awake at night.
Ask to be admitted to the Choosing Reconstruction private group and you may be able to find some photos of a similar approach. Please ask your surgeon if they have some images of their work as well. Mxx
