Thank you for your question and picture.
Your picture demonstrates breast ptosis probably with some degree of constriction/tuberous anomaly.
Thank you for the question.
Sometimes for “minor tubular breasts” breast augmentation is all that is necessary to improve the appearance of the breasts significantly. Although a “double bubble effect” is a potential complication it is not necessary an outcome of the procedure ( usually is not) is.
Tuberous breasts generally have a very narrow base and usually a long skin envelope. In the most severe cases of tuberous breast, a breast lift can be done through an incision around the areola, making the breast into a more rounded shape that the patient will be happy with. In many cases however, a lift is not necessary.
You should be aware that the final result will take months to see and that you will need to be patient.
The incision is usually confined to around the nipple/areola and may require a vertical/horizontal incision as well. The procedure involves making internal incisions to release the tight breast tissues, making a larger space for an implant, rounding out the lower breast crease, and correcting enlarged and protruding areola.
Make sure that your surgeon has experience with this specific procedure and is a board certified plastic surgeon.
I hope this helps.
