Should I go for a dual plane or submuscular revision? (Photo)

As long as you are not an active bodybuilder, or a routine weight lifter particularly with your chest, assuming you are otherwise happy with your implants in the subglandular position physiologically, then I would keep your new implants prepectoral, use Galaflex to support the pocket, downsize your implants, and do a full mastopexy leaving you with an anchor scar. This would accomplish skin tightening, areola reduction, as well as improved implant positioning with a better cleavage and closer midline. The important thing to note is that downsizing is absolutely possible, but you would have to undergo a full mastopexy. I don’t think it’s a mistake to change the pocket to a dual plane position, but I actually see no need for a more invasive procedure particularly since you have otherwise been happy with prepectoral implants.

Dear kamilast91,
I almost always place implants submuscular. It lowers the rate of capsular contracture significantly. In addition, it looks much more natural because the muscle provides covering over the implant so its not as round on the top. I've also noticed the implants drop less over time when they are protected under the muscle.

You have little tissue, so I would suggest placing the implants behind the muscle for better upper breast fullness and coverage. I do agree with going smaller. The vertical lift might do well for you and is less likely to stretch your areolae.
