Is it possible to get an areola reduction and release the constriction of the breast first and wait to get implants later on?

Augmentation isn't necessary to correct the tuberous nature of some breasts. By the way, tuberous, not tubular, is the correct term for the deformity as it describes breasts that are shaped like a tuber. In fact, it can be beneficial to do the procedure without the augmentation because the implant puts stress on the periareolar scar tending to make it not heal as finely.

I recommend a new technique called The Mini Ultimate Breast
LiftTM. Using only a
circumareola incision it is possible to reshape your breast tissue creating
upper pole fullness, elevate them higher on the chest wall and more medial to
increase your cleavage. At the same
time, the size of the areolas can be reduced.
If you are satisfied with the volume of your breasts then you do not
need implants or fat transfer but if additional volume is desired it can be
done simultaneously or later. If you gain
weight or have pregnancies, your breasts will expand and you may not need added
volume. Best Wishes,Gary Horndeski, M.D.

We perform many corrections of tuberous deformities in our practice.  The ideal treatment for you depends greatly on the degree of each deformity:  size of the areolas, how tight the breast tissue is, how constricted the base is, if there is an element of herniated glandular tissue, the texture of of your skin and breast tissue.  In some cases I perform a circumareolar mastopexy (Benelli) to reduce the areola and the herniation and reshape the breast first; then at a second stage place implants in.  Photographs are helpful: but examination by a board certified surgeon with great deal of experience with these cases is the best way to proceed.
