Do I have enough breast tissue for subglandular implants? (Photo)

The most common breast implant operation in the world is a sub glandular augmentation. While I perform mostly sub muscular augmentations there are cases such as your request where I am happy to perform sub glandular augmentations. The long term results may not be as good due to the increased rate of capsule formation and the decreased imaging ability for mammograms are well known. As long as you are informed of the risks and benefits of each operation then the choice is yours. Use of specific implants such as a high profile will allow for a 400cc size with out picking an implant that is too wide for your frame. Good Luck!

Thank you for the question and pictures. Yes, I think that you do have a significant amount of breast/soft tissue coverage;  the use of sub glandular breast implants is an option.
 Having said that, there are pros and cons to the placement of breast implants and the “sub muscular” position versus the "sub glandular position”.    I will try to outline some of the differences here;  you may find the attached link helpful as well.
I think it is in the best interests of most patients seeking breast augmentation surgery to have implants placed in the “dual plane” or 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 breast implants in the sub glandular position. The incidence of breast implant encapsulation (capsular  contraction)  is also decreased with implants placed in the sub muscular position.
On the other hand,  sub glandular breast implant positioning does not have the potential downside of “animation deformity” ( movement/ distortion of the breast implants  seen with flexion of the  pectoralis major muscle)  they can be seen with breast implants placed in the sub muscular position.  
Best wishes with your decision-making and for an oucome that you will be very pleased with. Make sure that you consider the longer-term outcome ( for example changes in body/breast with time/age) as you make your decisions.
