This question has obviously stimulated lots of discussion, given the number of my colleagues answering. The majority favor NOT lowering creases, usually because this "violation" has the potential for creating less aesthetic results in some patients. Basically, I agree, although every patient's anatomy is different, as are their goals regarding final breast size and what breast volume and skin elasticity they "bring to the party!"
Thanks for including photographs; they are quite helpful, but a physical examination is quite important in your specific case. It appears as if you have more skin laxity on one side, though this may simply be artifact because of your arm being elevated on the opposite side. Your present IMCs (inframammary creases) do not appear to be tightly adherent, and may well be amenable to being stretched by the (larger) implants you desire. Both standing and supine examination will help your chosen plastic surgeon decide what is possible, what is best, and what options exist to position your implants to yield the best aesthetic results.
In select cases, and you might just be one of them, lowering of the creases by the appropriate amount may in fact yield a better cosmetic result! There is always a (small) risk of "double bubble" when this is done, and not every case where this is more likely can be determined beforehand. I discuss this possibility with patients whose anatomy predispose them to this outcome, and we obviously do our best to avoid this whenever possible.
But simply saying "I never lower creases" is too simplistic, and an error in some patients where crease lowering is not only possible, but optimal! Better-looking results can be achieved by judicious choice to do this when needed, and yes, there may be an occasional double bubble outcome to correct.
However, I believe it is better to have to correct an occasional less-than-ideal outcome than to avoid doing the proper (better) surgical approach in those patients where the majority may have a superior outcome by doing so. Having the experience and wisdom to choose properly which patients this applies to is the key (not to mention having the humility to recognize that we will occasionally fail and have to make the necessary corrections).
The difference between great surgeons who try for superior outcomes (and occasionally fail) and everyday good surgeons who "always" choose the safe and formula approach is finding those who have the fewest re-dos. BTW, even those who choose the "standard and usual" still have failures and re-dos!
Just food for thought. See more than one ABPS-certified plastic surgeon and get a number of opinions. One will certainly resonate with you, and a consensus may even emerge as well!
