Thank you for your question.Your question is a very common one, as many women are interested in obtaining a certain degree of cleavage with a breast augmentation procedure. The primary reason as to why a patient would have a gap between their breasts post-operatively would be because they had a reasonable amount of space between their breasts pre-operatively. When performing a breast augmentation, we create the breast pocket and place our implants using the patients nipple as the center point. Using this anatomical guideline, patients who have wider set breasts will retain this wider set quality even after the implants are placed. It is not wise or advised for surgeons to use any other anatomical landmark when creating the breast pocket and placing implants as doing so would create an artificial and anatomically poor result (too lateralized or too medial nipples).For patients with wide set breasts, it is possible that a lower profile implant (one that is wider with less projection) may be indicated. If you have already chosen a board certified plastic surgeon, I would encourage you to discuss your concerns, your anatomy, and what you can realistically expect from a breast augmentation with your surgeon directly. If you have not chosen a board certified plastic surgeon, please consider scheduling a consultation to discuss the options available to you and your candidacy for the procedure. In my office, I offer complementary 3D imaging using the vectra system to help patients get a better idea as to how various implants would look on them. This is something that I believe you might find helpful. I hope that you find this helpful and I wish you all of the best!
