Hi there-I think it would be very difficult to answer your question without knowing more (including some things that could only be determined on examination, like the quality of your skin and your tissues), so please understand that for the best information your should visit an excellent surgeon with a lot of breast experience for a full consultation.Based on what you write and the photos you posted only, I would be very concerned that even if you were able to achieve your goal for appearance as a result of breast augmentation only, it would be a very short lived satisfaction indeed. Here's why- you say that your decline in breast volume and shape were the result of weight loss and aging... let's begin by understanding that the reason weight loss and aging cause these changes in most women is because of their effect on the elasticity of the tissues. As people gain weight, tissue elasticity is taxed and lost (how much is lost and how much weight gain is necessary for this to happen will depend on skin and tissue qualities of the individual, which are both inherited and lifestyle dependent) and while we are getting closer to being able to camouflage this, lost elasticity is generally lost forever. This means that trying to create the appearance of a firm, perky, youthful breast through augmentation alone is more than likely to actually cause you unhappiness once the lost tissue and skin elasticity, gravity, and the weight of the implant take effect on your appearance. I think the better question- the one you should be asking- is... "If I am going to need a mastopexy (breast lift) in order to achieve my goal, how can I maximize the chances of getting what I want and not regretting this course of action?"More than most other procedures, the outcome and your satisfaction with mastopexy will depend on who you choose to do it for you. Again, without seeing you in person I think it would be a bit irresponsible to try to be more definitive in my answer to your question, but my impression is that you will need a breast lift to achieve the outcome you describe. Accepting this now will help you avoid a second operation, additional anguish as you come to realize this after your first, and considerable added expense, but it makes it more important that you choose your surgeon carefully.
