What is the visual difference between subfascial and subglandular over the muscles placement? (Photos)

Hello and thank you for your question.  There is not much visual difference between subfascial and subglandular implant placement.   However, there are several advantages
and disadvantages to over vs under the muscle.  Under the muscle has the
advantage of lower capsular contracture rates, less risk of rippling, and
better visualization with future mammograms.  Most patients say that under
the muscle also has a more natural look and feel.  The size, shape,
and profile of the implant is based on your desired breast
size/shape, your chest wall measurements, and soft tissue quality. 
This decision should be based on a detailed discussion with
equal input from both you and your surgeon.   Make sure you specifically look at before
and after pictures of real patients who have had this surgery performed by your
surgeon and evaluate their results.   The
most important aspect is to find a surgeon you are comfortable with. I
recommend that you seek consultation with a qualified board-certified plastic
surgeon who can evaluate you in person.
Best wishes and good luck.

Thank you for the question.  I would not expect for you to see much (if any) "visual difference" between breast implants placed in the sub fascial versus sub glandular position.There are pros and cons to the placement of breast implants in 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)  that can be seen with breast implants placed in the sub muscular position.    Best wishes.
