Since you are a full year out from your implant exchange, what you see now is your settled result, so it makes sense to address it rather than wait longer. The two issues you describe often go together and usually have a mechanical explanation. Extra tissue on the sides typically means either residual skin and fat that was not fully addressed at the outer edge of the previous surgery, or breast tissue that has been pushed outward. The flat look at the outer bottom of the breast usually means the implant is not filling that part of the pocket — either because the pocket is tight there, because the mesh is supporting the implant in a way that restricts the lower-outer curve, or because the implant is sitting slightly more toward the middle than the natural breast border.The encouraging news is that both problems are correctable, and often with less surgery than your previous operations. Depending on the examination, the excess on the sides can be treated with liposuction alone if it is mostly fatty, or with a small skin excision if there is a true fold of loose tissue. The flat outer-lower area can be improved by adjusting the pocket so the implant fills that zone properly, by softening the tight area near the mesh support, or by adding a small amount of fat grafting to round out the curve. Which combination is right depends on what is actually causing the flatness — implant position, pocket shape, or thin tissue — and that can only be determined by examining you, especially since mesh was used in your last surgery and any revision needs to respect that support.The most suitable next step would be an in-person consultation with a board-certified plastic surgeon experienced in post–weight loss body contouring. During a physical examination, your skin quality, the areas of looseness on your abdomen and beneath your breasts, and your breast shape can all be properly assessed, and a clear plan can be mapped out — what to combine, what to stage, and what result you can realistically expect at your current, healthy weight.
