Will push up bras cause symmastia?

Hello,The best person to advise you on this is your operating Plastic Surgeon who knows your specific situation the best. If your Implants are an appropriate size for your chest and assuming careful surgical technique, you should be able to wear whatever bras you like but each Plastic Surgeon has their own preferred recommendations for bras.Take care

Thank you for your question.  At 18 months you should be fine without worry about displacing the implants with a push up bra.   I caution patients against wearing a push up bra in the early post operative period for fear of preventing the implants from dropping, and being too high up.  Your pectorals muscles prevent the implants from moving together and creating synmastia assuming they were released appropriately.  This far out, you are fine to use a push up bra.  All the best, 

Thank you for the question.  At this point, 18 months post breast augmentation surgery, you do not have to worry. Breast implants have "reach their final position";  displacement concerns (such as symmastia) with a bra  is not a concern.   Enjoy the outcome of the procedure performed.
