Should I Pay for Breast Augmentation Redo?

Every surgeon's policy varies and although you may be upset with the result, the surgeon may feel that they got the best possible result given the circumstances.
There may be many logical reasons for why your breasts remain uneven.
Going in to correct your problem is an opportunity to improve on the outcome but it also is an opportunity to make it worse. Every operation has a new risk of infection, scarring, etc. How badly does it bother you? Only you know. Given your desire to re-operate, I can surmise that it remains a significant concern but you need to be willing to undertake the risk of this new surgery. I am assuming that because the surgeon is charging you, they do not feel that it is worth the risk. In my opinion, I would have to agree that a 30cc difference is relatively minor and not advise a patient to seek correction.

When you enter into the informed consent for a procedure and sign the consent it IS a contract between you and your surgeon. I am sure there is something in writing stating revisional procdures will entail additional costs to you. There is most likely wording about the lack of warranty and the possibility of the need for additional procedures. These clauses in the consent would make it legal and ethical for your surgeon to ask for a fee. I personally would not chrge a fee in this situation, but there still would be facility and anesthesia fees. This is well known to my patients prior to surgery!
Correction of asymmetry is challenging and a "homerun" may not be hit on the first attempt.An implant change in this situation is not uncommon. I suggest you discuss this issue with your surgeon to see if he would waive or reduce his fee. Keep in mind, if the consent you signed has what I listed above, he legally does NOT have to. Good Luck!

One thing we all have to keep in mind is that surgery is an Art and a Science. It is impossible to predict with 100% certainty how a surgery will turn out. With that said, if something was done differently that what you discussed preoperatively then you may have cause for concern. From you question you say that one side had 300 cc and the other 380 cc. If you and your doctor estimated a 100 cc difference, then there would only be a 20 cc difference now. Studies have shown that the eye cannot perceive a 30 cc difference between breasts, so you are within the margin of error. If you provide before and after pictures, then we may be able to give you better advice. As for the money, in most cases if there is a true technical error by the surgeon, then they should waive their surgical fee for any correction. You would still be responsible for any operating room or anesthesia fees. If you only paid $5000 for your initial surgery (I am assuming this does not include the price of the implants) you got a very good deal to start with. Third, why are you having saline implants placed? If you are going back for surgery, then you may want to consider having them switched to silicone. Good luck.
