One breast is bigger than the other. (photo)

Sorry to learn of your distress and situation. While a mistake such as you describe can theoretically occur, it would be highly unusual. At one day post-op asymmetry is difficult to judge since early post-operative swelling is often asymmetric. However, if the intention was to indeed to use two different implants to correct asymmetry and a true mistake was made, it would be best to revise your surgery as quickly as possible to make the correction. This is something you should discuss with your plastic surgeon as soon as possible. As far as you knowing exactly which implant you have in which breast, it is your absolute right to have this information. You are entitled to access to your medical record, pure and simple. There can and should be no secrets withheld from you.  A word of advice to you. If this error indeed occurred, your plastic surgeon will presumably feel terrible about it, and perhaps defensive, worried that you will be upset and potentially litigious. My advice to you both is to be open and transparent about everything and to try to resolve this as quickly as possible to achieve the result you are hoping for. Best of luck to you.

It is difficult to make an accurate assessment the day after surgery. Normal swelling can distort the appearance and is not generally indicative of your long-term result.  Regarding what implant was placed on each side, the only one who can answer that is your surgeon. Discuss your concerns with him or her. Best wishes to you!

Thanks for the question. At this point of your post op the swelling is normal. In my practice, after performing a BA I recommend to my patients to limit the movement of the arms for two weeks. After that, you can move your arms taking care and always with common sense. In this regard, it's not advisable to carry heavy weights to prevent the implant out of position, and allow the formation of the physiological capsule around the implant, also to avoid pain and breast swelling. Kind regards

Thank you for sharing your question and photograph.  Unfortunately at this early stage of healing there could be a number of factors affecting your current results, namely swelling.  Though I appreciate your size discrepancy in your photograph, only your surgeon can tell you which implant went into which breast.  Voice your concerns to your surgeon.  

it should state which size went in which breast and it should also be on your breast implant card which will be given to you by your surgeon. 

Thank you for your questions and photos.
It is impossible to evaluate any symmetry at this early stage .
You should be having regular post operative follow up appointments with your board certified plastic surgeon that performed the surgery.
There are mutiple factors in early post operative stage that affect appearance-
Muscle spasm, pre operative asssymetry, hematoma, normal swelling...

Best of luck to you.

Based on your photo, your right breast is significantly larger.  This may be due to swelling, which typically resolves with time.  However, I would recommend that you be evaluated by your surgeon to determine if this is due to another issue, such as a hematoma, that would need to be addressed more urgently.  Best of luck!

You need to speak with your surgeon to determine what the issue may be, only he would have the correct answer.
