Depending on your goals for the size of your breasts, I do think that you would be a candidate for breast enhancement via an augmentation alone.
This is not to say, however, that I think you would achieve your best outcome through this approach... This would be a compromise procedure, with a necessarily compromised outcome- no breast lift scars, but less than ideal shape. Your nipple would still be a bit low on the breast, and the volume of the implant may sit a bit lower on your body than you would prefer.
If you asked me a different question- "What would you recommend if I said I wanted the most beautiful breasts possible?" Then I would say that your best bet is to have a breast lift with your implants.
As far as the technique goes, there are of course many different techniques for lifting of the breast... But in my opinion, it is a mistake to think that the techniques are all options for all patients, and that the choice of breast lift technique should be based on the patient's preference for scar location and size...
It is important to understand that each different breast lift technique will necessarily alter the shape of the breasts is a very characteristic way, and that if an inappropriate technique (based on the starting shape of your breasts) is chosen, you will most likely not be happy with the shape of your breasts after surgery. And in my opinion, it's all about the shape...
Some of the worst outcomes I see are in women who had one breast lift technique or another because of the scar they wanted to have- despite the fact that the shape of their breasts made them poor candidates for the procedure they underwent. And this is very difficult to correct after the fact.
I definitely understand when patients say they are concerned about breast lift scars... I know what you're worried about....
I think that the key to achieving the goals for patients like yourself is to realize that if you need a breast lift to achieve the ideal shape- do the breast lift. But do EVERYTHING possible to make the scars as inconspicuous as possible. With an appropriately aggressive approach to scar management, guided by a very experienced breast surgeon, you can have the shape you want, AND inconspicuous scars.
