Placement of breast implants - Breast augmentation - Breast implants - Forums & Discussion 

There is no difference. Where the choice of surgeons implant to be placed depends on the thickness of tissue that covers the skin imlant and quality and degree of ptosis.

It depends on preoperative tissues evaluation

Implants placed under the muscle have a somewhat smaller degree of capsular contracture, but postoperative pain is also greater, and patients present what is called a "dynamic breast", as it moves along with movements of the arms. The only absolute reason to place them under the muscle is in very thin patients that would show the border of the implant if it is placed directly under the gland, because they lack of sufficient tissue to camouflage the presence of the implant. It is also recommended in patients operated for capsular contracture in a subglandular position, to reduce the risk of recurrence.

Over the muscle technique implies implant  placement  over the muscle in the sub-glandular position, completely in contact with the breast tissue.    The  result   of   implants  over  the  muscle  provides  a round  augmented  look  in  many  patients,    but  only a few  women prefer the round and somewhat  less  natural look.   In the "over" approach the implants are inside  the breast.    Advantages are ease of the surgery, which can be accomplished by almost any surgeon,  avoidance  of  mastopexy  in  mild  ptosis  (although it usually makes the ptosis worse later),   less post-op discomfort, since only skin and fat are cut.     This approach allows insertion of oversize  implants,  which is again  what  some  women  want. Disadvantages   are  marked  interference   with  mammograms , clear  visibility and feel of  implant edges,  visible and palpable rippling of  the  skin over the  implants,   especially  with  any  textured  implants, higher  rate  of  capsule contracture,    high  rate  of  later implant downward migration or "bottoming-out",  and difficulty correcting later post problems when they occur.    For the above reasons we  do not  recommend   implants   over   the   muscle   anymore.
Under the muscle-implants are placed  under  the pectoral muscle via an inframammary crease incision, under the muscle fascia at  the lower pole of the implant to allow it to enter  the space  under  the  muscle.   With  this  approach the implants are  mostly behind  the breast tissue under the muscle layer.   This approach has the advantages of  mostly separating  the implants from the gland thus facilitating  unobstructed  mammography,  a  more  natural  look with  a  soft  transition from the flat  of the upper chest  wall  to  the round shape of  the implant,  much  less visibility and feel  of the implant  edges,  usually  no  rippling , and  low risk  of  capsule contracture.Disadvantages include a bit more discomfort early post-op,  technique a bit  more difficult than  over  the  muscle,  and  the loss of the lower  pole  support fascia which can be prevented by strategic suture placement to recreate the submammary crease thereby diminishing this risk. This technique being more favourable on the long run, we preffer this technique to the over the muscle implant placement.

Better coverage under the muscle with less upor pole visible edges.

If implant is inserted behind the pectoral muscle, the muscle is cut, and if it is inserted behind the breast, a pocket is created behind the breast for insertion of implant.
