Why is happening to my left breast? (photos)

Your surgeon elected to lower your fold and when this is done the old fold often can be seen and if the implant settle further then  you get the result you have now. One can go back in and release some of the old fold and repair the current fold to a higher fold with sutures usually but occasionally  a supporting tissue matrix is needed which ads about 2500$. Let us know what you and your doctor decide to do please.

Dear  KG2302,it is hard to tell for sure without an examination. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD

Such blunting of the lower fold can occur when an attempt is made to lower the fold and make it even with the other side. If the fold was lowered and then secured with suture it could eventually round out, however, after 4 months I would’ve already expected this to have happened. At this point, it would be best to discuss with your surgeon and see what the options are. A fold revision on that side could be considered. 

Dear KG2302, what you have is called a double bubble deformity.  This was caused by your surgeon's attempt to lower your inframammary crease which was necessary to round up your breasts. Originally the distance between the lower edge of your areola and your crease was very small (which is called a constricted or tight lower pole) It worked very well on the right side but not on the left.  Fortunately this is correctable and your surgeon should be given the opportunity to do this for you at a special price or no price at all (that's between you and him/her) If you loose confidence on your surgeon then you should get more opinions before you commit to correction.

Hello and thank you for your questions and photos.  Unfortunately you seem to have just had a very poor technical procedure performed with the poor result that goes along with it.  I'm sorry to say that you will likely need a revisionary procedure from a surgeon that has experience with difficult revisionary breast surgery.  A new fold can be recreated but it is a much more difficult procedure than the initial surgery.  I would recommend that you seek a consultation with a different plastic surgeon in your area who is board certified and experience with breast revision surgery.Best wishes!Daniel Brown, MD, FACSBoard Certified, American Board of Plastic SurgeryMember, American Society of Aesthetic Plastic SurgeonsMember, American Society of  Plastic SurgeonsCastle Connolly Top DocReal Self Top 500
