Would switching from 450cc Moderate Plus to 675cc High Profile improve cleavage? (Photo)

Unfortunately breast implant shape and profile are very misunderstood by doctors and patients alike.  There are two main reasons that your breasts are spread apart and lack the cleavage that you desire:#1 You have what surgeons call a "dual-plane" technique which places the superior part of the implant under the pectoralis major muscle.  This ensures that the breast does not approach midline and it continually pushes the implant farther away and lower.  This is why the inferior pole of your breast is so stretched out particularly on the left.#2  The profile of your implants is already too high!  The thing most dont realize is that profile really describes the relationship between the width of the implant base and how far it sticks out.  Thus higher profile implants and MORE NARROW and lower profile implants are wider.  The higher the profile the lesser the ability for the implant to occupy the full breast "footprint" and the lower the ability to give you clevage.The main reason that this is not apparent to most plastic surgeons it that most use submuscular/dual-plane techniques and thus have already given up the ability to fill the more midline "clevage area" and thus need to select higher profile narrower implants.For these reasons I never use high profile implants but I also use a very different technique that allows me to sculpt a custom shaped breast for each patient that occupies the full ideal footprint and shape of a breast on the individual patient's body.  The technique is called "Cold-Subfascial Breast Augmentation" and is not under the muscle but importantly is VERY different from over the muscle.  It is different because it preserves a strong structural tissue called fascia that drapes and shapes the implant like a bra inside the breast.  With this technique I also prefer to use anatomically shaped form stable "gummy bear" implants.  The result is a breast that has a very soft start near midline and disappears up toward the clavicle in a very natural shape.I would recommend revising your scars at the same time and redraping your inferior pole.  I hope this helps!All the best,Rian A.

Yes it would, but I recommend redoing your lift as well for better cleavage, scars, and symmetry.Ary Krau MD FACS
