Synmastia is a medical term that describes what happens when breast implants are placed too close together and actually touch.
It can also refer to a natural condition unrelated to surgery, when natural breast tissue touches in the midline or sternum of the chest, resulting in what may appear to be just 1 breast.
Synmastia is aesthetically not normal.
For example, women with very large natural breasts, typically, will not touch in the midline.
Without the support of a bra, your breasts should normally fall slightly down and separate in the middle.
Most women will be able to see and feel their sternum and the bony chest plate.
This is normal, even with breast augmentation, because your breasts should also do this after surgery.
With or without breast implants, your breasts will typically touch only with a cleavage inducing bra or underwire bra.
Without any support your breasts have about 1 inch or 2.
5 centimeters of space between them.
Some women with natural breast tissue have a larger distance between the right and left breasts.
Choosing breast implants with the proper profile is the key characteristic to ensure that you have the appropriate amount of space between your right and left breasts.
The width of your breast implant should match the width of your breast tissue.
To achieve the best long-term result, your Plastic Surgeon needs to measure you before surgery and help you decide on the appropriate width implant.
Plastic Surgeons can avoid synmastia during surgery by creating the perfect breast pocket for the implant.
If you create a pocket that is too wide, the implants will touch in the middle.
Although rare, it can happen.
