Thanks for posting the photo. i can see you have had a left mastectomy and implant reconstruction and it looks like there was a symmetrising procedure on the right (wise-pattern reduction mammoplasty). It is a difficult problem to deal with and requires a very high level of expertise. I am not in any way criticising your original surgeon as it is often not clear what the outcome will be until much later on.
If you were my patient, and very much depending on your hopes and desires, I would be looking at leaving the right side alone and revising the left side. I think the lower breast crease (infra-mammary fold) needs to be reconstructed so that it is higher and matches the right side. At the same time I would replace the implant for one that is more closely matched with the right side volume. Finally, at the same surgery, I would undertake a lipofilling procedure to give more upper-pole fullness, a more natural shape and look. I would expect a good result from this but would also caution that further lipofilling procedures may be required in the future to get as near-to perfect a result as possible. I hope this helps. Best wishes, Chris.
