Synmastia and Breast Implant Malposition

Aug 19, 2011 by

I had never heard of synmastia until a few years ago- it used to be called “uni boob” or “breadloafing”. Synmastia is a type of implant malposition that results in the breast implants coming together in the middle of the chest- forming a “uniboob”. Is synmastia the result of a doctor placing implants very close together in the middle of the chest to increase the cleavage? Or the result of the implants moving? Possibly a bit of each.

As detailed prior- always choose a certified doctor with ample before and after pictures and assist the doctor by providing information about the post augmentation look you desire.

Certainly much of the cause of the implant moving (malposition) is due to the implant itself as the study given to the FDA by Inamed cited malposition in 5.2% of primary breast augmentation cases that used smooth or round implants.

If the implant does not form a close bond with the tissue, it can move. Most of the time the implant will “drop” or settle; synmastia (the implants coming together) can be more common in women that are a thin or have a narrow rib cage. It can also result with a large implant as the malposition will be magnified with the larger size.

Some pictures from www.breastinfo.com:

As you can see in this picture, synmastia will almost always lead to a re-operation to remove, replace and re-position the implants and breasts…synmastia does not look natural.

You would think this picture is a case of implant malposition or the implants moving- I doubt a patient would accept this result and that the implants moved over time. This shows the implants did not form a good “capsule”, this can be the result of the type of implant used- smooth and textured implants have a much higher rate of malposition than Polyurethane foam implants.

Synmastia or implant malposition

Here is another good example of the implant malposition with the implants coming together in the middle of the chest. It appears the implant on her right side moved more than the implant on the left side based on the position and general shape.

Of course it is possible the doctor made an error in placing the implant, but with Inamed reporting to the USA FDA that 5.2% of implants suffered from malposition- this makes me think there are not 5% of surgeons making  a mistake, but the malposition issue has more to do with the type of implant surface used.

There are more good images on the www.implantinfo.com website, please make sure and have a look and read.
