Diagnosis of symmastia?

I had a breast augmentation about six months ago. I am 5’6” /115 lbs and got 350 cc implants. Two weeks after breast augmentation, I noticed that the skin between my breast is slightly raised and I can push it down to my sternum. The surgeon told me it was just swelling from surgery; that it will be normal after three to six months. But now the same condition still exist. I am worried that I have symmastia? I sent my photo to my surgeon and was told that is not symmastia. It’s cleavage.

It sounds like you may have a small degree of symmastia, although, without pictures or an examination, it is hard to say exactly what might be going on.

The best thing to do is to have a consultation or two with board-certified plastic surgeons who have extensive experience with symmastia repair.

You should know that most surgeons do not have this experience even if they say they do. It may mean sending pictures via email or traveling outside of your immediate area, but it is generally worth the effort.

I hope this helps.

You have a petite frame and full sized implants. You may not have true symmastia, but an artifact of your body habitus and the implants. There may be some bow string phenomenon of your skin across the natural sternal tissue that usually is fixed across the sternal bone. The tethers across the sternal bone can be anteriorly displaced by the projection of the implants in their pocket. If this bothers you the intervention is to place acellular dermal matrix in the medial side of each implant pocket. It acts like a permanent brassiere to keep your implants a little further apart than your anatomic sternum and implant relationship that now exists. If it stays stable in appearance over time, you do not need to act. If it bothers you, then it will probably need to be discussed with your surgeon. I would be happy to be of assistance to you if you are not getting your concerns addressed.

Symmastia is an actual opening where a space between the two breasts and the implant can move from one side to the other.

Symmastia refers to a loss of the medial definition of the breast mound. This is occasionally seen in subglandular augmentation when the midline is overly dissected.

Regarding your specific question, you may have had some inadvertent violation of the medial border but it is not a true symmastia unless the medial border is lost. Depending on the degree of augmentation, there will always be some stretch.

As always, discuss your concerns with a board certified plastic surgeon (ABPS).

I had breast augmentation 6 weeks ago and they seem to have settled but i'm unsure. I'm feel like they are too small. I have tried on bras and I measure into a 32DD as well as 34 C sister size (I was a 32a prior). How long will it take for my breast to drop and fluff? I also have a gap in between which makes it difficult to achieve cleavage.

I had a breast augmentation on April 8th. I feel like they are shaped funny and not as big as I wanted. I went submuscular. Prior to the surgery, I was a 38 B and now I have 560 cc silicone gel Inspira implants. I was hoping to be a DD. Should I have gone bigger? Will my breast take a more natural shape? When is a good time to get a new bra, and will I be a DD once my breasts have settled and healing is complete?

I have friends who've gotten 500cc's and their breasts are quite big. After trying the 650cc sizers, they seemed to compliment my body more. Is there a big difference between the two sizes? Is 650 too large?

I just had surgery yesterday and I got 355cc's. They look so small in my surgical bra and wrap. I'm worried that they won't be big enough. Do you know what size I might be once the implants settle? I'm hoping small D.

I thought I was getting 400cc high profile silicone but my PS said they'll be 400cc moderate plus. I wanted a natural but big look, a D cup, and a small gap. Maybe that's why he chose those? Is there much difference in projection?

My breast augmentation is next Saturday and I am hesitating between 225 and 250cc submuscular silicone! I am a 32A/tiny B and fill up a 32B bra at Victoria's Secret. I am looking to be a full B/small C. I'm 5"6 and weigh around 100lbs. I am so scared I'm going to look disproportional and fake, but am also scared this is going to make me go too small. My goal is to look natural and proportional, while at the same time have a nice rack. Which implant do you think will give me the desired look?

I'm a little lost on the XL implants matter, that I personally like. Are they really unsafe? What are the reasons for that? It seems most PS don't recommend/perform them. Is it by lack of experience/expertise? Idealism? Are those PS who perform these procedures just "warriors" responding to a well present market? I would be curious to hear some honest answers, leaving the politically/socially correct behind. Thanks in advance.

I am 5"4 and 145lbs. I am currently a 34C and would like to be a Dcup. My PS recommend a lift. I informed him i wanted implants but still want a natural look. PS recommended 485cc smooth moderate plus silicone obove the mucle. Possible mini lift during surgery depending on how the implant looks during surgery. It just sounds like a lot of CCs. It doesn't feel right and now I'm freaking out.

I'm currently a large C-cup. My doctor said with 600cc I will end up around a DD. I'm fine with that but 600cc seems really big. Can my frame really handle that big of an implant and not look like Dolly Parton? I'm 5ft 8 in tall, 160lbs, size 10, wide shoulders.

I know there is a vast amount of factors that go into breast augmentation, lifts, and implant manufacturer costs alongside anesthesia, facility, meds, and other costs. But in your experience what is a ball park cost range you typically see for breast augmentation, and breast augmentation + lift. It'd be very helpful if you share a range like 9-10k or 6-7k, etc. Thanks!
