Breast reduction 2 years post-op. Too much was removed, what can I do to fix it?

Go on some consultations to be examined in person. Most likely you would end up being advised to consider breast augmentation with implants to restore projection and volume. Some patients who have had prior reduction may need a revision of the lifting at the time of implant placement to get a perkier, fuller look. Fat transfer may be another option, depending on how much volume you want to add. Surgical simulation software and sizing kits used in the office help the patient understand potential options and possible outcomes with different sizes of augmentation.

but if your fold has been obliterated, a reverse tummy tuck would help re-establish a fold and a better look.  An exam is required and I hope you can resolve this to your satisfaction.  For more volume, you will either need fat grafting or implants and that is something you would discuss with your surgeon.
