I had congenital symastia, when getting repair I opted for an implant as well I'm worried surgery didn't work? (Photos)

Usually a breast augmentation would not fix congenital symmastia. I don't think you should expect this result to change with time. You should talk to your Doctor about other ways to correct congenital symmastia.

Hello,Thank you for your question and photos. You appear to be very early post op. Swelling in the tissues is expected at this point and will take at least a few more weeks to subside. I recommend that you follow up in person with your surgeon to determine that you are on track and discuss any concerns.All the best 

 I am sorry to hear about your concerns after breast surgery.  Personally, I think that the use of sutures to correct congenital symmastia can be problematic, both from the standpoints of predictability of successful repair as well as from the standpoint of aesthetic outcome.  For example, I do not think that the use of sutures on native breast tissue "holds" well.
I have had the opportunity to help several patients with congenital symmastia  utilizing different techniques; I often combine liposuction surgery of the pre sternal area with breast augmentation surgery. A second stage operation (capsulorraphy) may be helpful in improving the “definition” of the medial breast border (cleavage) if necessary.  Sometimes, the use of acellular dermal matrix may also be helpful when it comes to improving the definition of the "cleavage area", decreasing visible skin tenting, and preventing breast implant movement too far towards the sternal area. Best wishes.
