Switching from submuscular to subglandular? (photos)

From your photos, it appears that the double bubble crease needs extensive release and probably consider  repositioning of the implant to the submammary plane from the sub pectoral plane. This has been helpful in my practice when such discrepancy is a problem.

Yes one of your options is to switch from submuscular to subglandular position of the implants. Any good breast surgeon certified by American Board of Plastic Surgeons should be able to do that. I have done this on a couple of instances for the same reason and it solves the problem.  I would recommend you have form stable silicone implants for this.  You don't have a lot of soft tissue coverage and a saline implant will probably show ripples.
