Do I have symmastia? Is it difficult to repair? (photos)

Thank you for this challenging question.  I am sorry you are going to need a revision of your breast augmentation.  Symmastia is a condition where the soft tissue of the breast bridge over the sternum, therefore by definition, you have symmastia.  Interestingly, when you flex your muscles, you are able to separate your breasts, but unfortunately they go back to a symmastia position once your muscles are in a relaxed position. 

There are several procedures that will assist your surgeon in bringing your two breasts to a more natural, less connected positiion on your chest, but all procedures for correction of symmastia are moderately difficult, but I would not categorize them as extremely difficult.  Therefore, if you pick a Board Certified plastic surgeon with experience in correcting malpositioned implants, your chances of success are reasonably high.  The use of a thongbra post operatively would definitely be an advantage for keeping the medial aspect of both breast pockets closed. 

Yes, it appears that you have symmastia.  It is moderately difficult to correct, but it can be done when your PIP implants are replaced.  A Thong bra would definitely help to support the repair.  Good luck!
