Is it possible for implants to move from under the muscle to over?

Hello, it is possible for implants to move from under the muscle to over, but extremely unlikely. I have seen it happen, but only on one side. More than likely, the doctor may be mistaken about the placement. Or the mammogram tech is mistaken about the position. I would wait for the final mammogram reading from the Radiologist to determine what position your implants are in. Best of luck!

I would always take what a tech says with a grain of salt and technically they are not really supposed to discuss the results of a mammogram as it needs to be read by the radiologist. I think most likely what she is seeing is the lower part of the implant is under the gland which everyone who has a submuscular implant is actually not under the muscle in the lower part of the breast but under the gland. I have attached a video explaining why.

I cannot imagine nor have I ever seen an implant move to a subglandular pocket from a submuscular pocket as the breast tissue above the muscle would have to be separated from the muscle and it's not possible for an implant to do that.

Hello and thank you for your question! When implants are placed "under the muscle" the most common technique is actually a "dual plane" technique whereby a portion of the pec major muscle is "lifted up" in order to accomodate a space for the implant between the muscle and the chest wall. The implant ends up with its top portion covered by the muscle (actual percentage variable dependent on patient and technique variation) and in the bottom portion it is actually not covered by muscle but only by the breast tissues. Over time, changes in age, hormones, tissue quality and gravity in general will result in the breast tissues sagging. It is possible for the implant to descend downwards as well. It is speculation, but your implant may only be minimally covered or now not at all covered in its top portion by the muscle depending on the degree of these changes and this is why imaging may show "no muscle" in front of the implant. The question of "moving/flipping" from under to above the muscle is not very likely as the the breast tissue connections to the muscle below it would need to be surgically separated to create a true pocket/space for an implant.
