If I have mild tubular breasts & I were to receive a regular breast augmentation, would I develop double bubble deformity?

In your before photographs, your breasts were asymmetrical in volume, shape, position and lying low on the chest wall.  I would have initially recommended a breast lift.  However, the best way to eliminate double bubble is explantation and lift using The Bellesoma Method.  The implants are removed, your breast tissue is reshaped creating upper pole fullness, elevated higher on the chest wall and more medial to increase your cleavage.  Vertical scars are avoided, nipple sensation (in 95%) and the ability to breast feed are maintained, if not injured during your previous surgery.  Later, fat transfers can be performed if additional volume is desired.  Implants are not lifetime devices.  8% fail within the first year and 30% fail within six years.  Fat transfers are permanent and incorporated into the body.Best Wishes,Gary Horndeski, M.D.

Thank you for this in-depth question about tuberous (tubular) breasts.  I'm assuming the first picture you showed was, in fact, you.  Your picture is one of a classic Type II tuberous breast with constricted lower pole.  Your first surgery for augmentation of tuberous breasts show the classic misunderstanding of the uniqueness of tuberous breasts which always require a periareolar incision and release of constricted tissue.Transaxillary or inframammary incision of your type breasts routinely lead to a double bubble deformity, also known on lateral view as a Snoopy Nose deformity.  Release of the inferior constricted portion of your tuberous breast without placement of implant and/or tissue expander, in my opinion, is without merit.A secondary or redo surgery once you have a double bubble must release the constricted portion of your lower breast, to include muscle and fat, and should be from side to side.  Placement of a breast implant sizer during the surgery should tell the surgeon whether a double bubble will be evident in the post operative period.  An experienced surgeon will either place a tissue expander at this point or have the patient wear a tight bando for several weeks or more to force the implant to break down the double bubble.  Unfortunately, the problems you present are not unique.  The good news is there are many excellent Board Certified plastic surgeons experienced in the correction of tuberous breasts in Chicago.  Your job is to consult with several of them and choose the surgeon who seems right for you.

Hi, thank you for sharing your question. 
The ideal way to get
the best advice would be after an in person evaluation, however based
on your proposed scenario, I would say that a breast augmentation alone may only correct a mild tuberous breast deformity. If your situation is more advanced, you will require maneuvers to prevent a sub-optimal result an possible even a double bubble. 
Consult with a board certified plastic surgeon to review all your options. I hope this helps. Best of luck!
