anyone have implants put in over your pectoral muscle.?

Mac, 

I do not have an implant. I had DIEP reconstruction. 

However I did research this and learned a great deal on this site as well. When a woman has breast augmentation, there is opportunity for a choice of above or below the pectoral. When a woman has breast reconstruction, she is usually reconstructing with NO breast tissue left, therefore there is not a choice and below the muscle is necessary. 

It sounds as if you have a unique situation with the fat grafting, but it sounds as though the implant would still need to be placed under the muscle. 

The reason implants are put under the muscle in reconstruction is multi fold: protection of the implant, support of the implant (to reduce risks of migration) and coverage to reduce any rippling, oh, and reduce risk of capsular contracture which is riskier in over muscle implants, even for augmentation patients. I have seen a couple women on here get them over the muscle, but have not seen their long term results. I have also seem some examples on the internet but to be honest, I was not impressed with their appearance.

I never had TEs as I went direct to implant with Alloderm, so cannot compare to what TEs may feel like (I have also never had radiation, so can't speak to that either), but what I can say is that I am very active - I also kayak, run, swim (a bit), hike, scuba dive, weight train, and so on and I honestly have no issues with my implants. I don't know if it was luck, my PS's skill, the surgery procedure I had, that I was in great shape and health before, but my implants are very comfortable and do not cause me any issues with my activity. I was aware they could, and there was a risk, but they just haven't. They are firmer than my natural breasts were, but still soft and do feel like part of me...to point I really don't think about them much, they are there just like my arms are, or whatever. It does not feel like anything is "stuffed under pec" though of course that is where they are.

That being said not everyone has that experience, and I don't think you should get an implant if you are not comfortable with the idea, and I also know that with rads implants are generally contradicted as the risk of failure is higher...though this risk is reduced it seems with fat grafting and/or lat flaps, etc. It sounds like you may have other issues, like fibrosis, that may add to complications for you. I am not sure an implant over muscle would be a solution or not for you, as there are still those risks above (and I am not sure how they are reduced by BRAVA fat grafting).

TEs are also a bit notorious for being uncomfortable as their purpose is to stretch the tissues. They have hard backs and harder shells than implants, and this can create pressure points, etc.
