Over the muscle or under for 700cc breast implants? (Photo)

Thank you for the question and picture.
In general, I think it is in your best interests (and that of most patients seeking breast augmentation surgery) to have implants placed in the “dual plane” sub muscular position.  This positioning allows for more complete coverage of the breast implants leading to generally more natural feel/look  of the implants in the long-term. This position will also decrease the potential for rippling and/or palpability  of the implants (which may increase with time, weight loss, and/or post-pregnancy changes).
The submuscular positioning  also tends to interfere with mammography less so than in the sub glandular position. The incidence of breast implant encapsulation (capsular  contraction)  is also decreased with implants placed in the sub muscular position. The main downside with sub muscular breast augmentation is the potential for animation or flexion deformity; patients will note movement of their breast implants when they flex/utilize their pectoralis major muscles.
I hope this, and the attached link, helps.

Thank you for your question. Its difficult to comment without an examination. First ensure  your surgeon is a specialist plastic surgeon and consider two opinions as using very large implants to fill out a stretched breast envelope is not always the best option and a smaller implant in combination with a lift/skin tightening procedure is safer and will be a much better option in the long term.700 cc implant is a very large implant. Visit the Australian society of plastic surgeons website to ensure your surgeon is a plastic surgeon. 

You are far better to go under the muscle in my opinion. You will have a much more natural appearance even going to such a large size of implant and that appearance will last far longer than if you go over the muscle.Be sure you talk to your surgeon about the width of the implant and what your skin and soft tissue will accommodate.Good LuckDr. JA.
