5’8, 145lbs, breast augmentation with mild pectus excavatum & planning to go with 255cc & 275cc, MP (Photos)

Thanks for your question and photos. It appears that your lecture is not severe and you therefore probably should be too concerned about that. The implants you are considering are relatively small which is good if your goal is a natural appearance that stays “below the radar”. Your plastic surgeon is your best resource for additional questions and concerns. Best of luck to you.

Using differently sized implants can help improve asymmetry. The difference between your two implants is only 25cc. For reference, this is less than two tablespoons of volume. This may provide a bit more balanced look to the breasts. Your surgeon may have sample implants you can try on to help you visualize your look after surgery.
