The most common answer other than implants, which remain the best solution even after difficulties you may or may not have had, is fat grafting. But you cannot fill the cavity with fat and expect it to survive, so multiple sessions above or below the pocket would be necessary, and proper technique is essential to get as much fat as possible to survive.But THAT is precisely the problem! The fat that does not survive (usually 50-65%) can cause scar fibrosis, lumps, and microcalcifications, all of which can interfere with the mammographic detection of breast cancer. I and many of my ABPS-certified plastic surgeon colleagues are not recommending fat grafting for breast enlargement because of this. There are equally well-trained and ABPS-certified colleagues who do not have a problem with fat grafting to the breasts, and time will tell which set of surgeons is more prudent with the lives and well-being of their patients.Thus, in the absence of fat grafting, implants remain the best option. Brava suction devices have been used for years but work poorly and yield no more than 1/2 to 1 cup enlargement, and this often regresses with time, so most of us do not recommend this device either. Interestingly, those PS who recommend fat grafting also use the Brava device to stimulate vascularity that is said to enhance graft "take." I personally believe this is of little long-term value.BTW, this is why I tell patients that implant removal should be done only as a last resort, as the pre-augmentation appearance is almost never re-established after implants have stretched the skin and compressed breast tissue, not to mention flattening the ribcage slightly. These living tissues respond to the presence of the implants and do not "return to normal" after removal. Any ABPS-certified plastic surgeon with experience in breast implants can give you advice on options going forward, including information about the newest generation of cohesive implants, which have much fewer difficulties than older types of implants.
