Hello and thank you for your question and photo. Based on your photo, you do have very mild pectus carinatum, but this should not prevent you from having a good result after breast augmentation surgery. Your surgeon will likely recommend selecting implants which have a higher projection which will minimize the appearance of deeper cleavage. Also, a dual plane technique augmentation, which will give your final result greater lower pole fullness, can also help give you a very natural and attractive look. Schedule an in-person consultation with a board-certified facial plastic surgeon in your area for a full exam and consultation. Best of luck! Michael Eisemann M.D. Plastic Surgeon Houston, Texas
