Thank you for the question and pictures.
You should be commended on your way of thinking: you will be happier with your breasts if you achieve the “end shape and fullness factor" with the scarring an important ( but secondary) concern. I also think that you would benefit from the use of breast implants; otherwise you will likely be disappointed from the “fullness factor” standpoint.
I think the type of mastopexy you would benefit from is a vertical mastopexy with an incision around the areola and vertically. Exactly the procedure that is performed depends on your goals in regards to size, shape, superior pole volume etc. There is no good way to do this with “little or no scarring”. Based on experience, I would suggest that your 1st concern should be obtaining the best results possible (scarring concerns should be secondary). Most patients undergoing this procedure will accept scarring as long as their overall goals in regards to size, shape, contour and symmetry are met.
It will be very important to communicate your overall goals with your surgeon. In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural” or “C cup” or "fake looking" or "top heavy" means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate.
If you decide to use implants ( for example to achieve more superior breast pole volume)
I use intraoperative sizers and place the patient in the upright position to evaluate breast size. Use of these sizers also allow me to select the breast implant profile (low, moderate, moderate plus, high-profile) that would most likely achieve the patient's goals. The patient's goal pictures are hanging on the wall, and allow for direct comparison.
I have found that this system is very helpful in improving the chances of achieving the patient's goals as consistently as possible .
By the way, the most common regret after this operation, is “I wish I was bigger”.
I hope this helps.
