Can any one please explain benefits/disadvantages to this internal bra method?

Internal bra is not needed for primary augmentation.  Stitches placed in the muscle and fat will not hold and therefore not effective.  In revisions, internal sutures can be placed  because there is capsule to sew to.  If a breast augmentation is done well, an internal bra is not needed to get good long term results.

Thank you for your question. Please speak with your surgeon for rationale as he/she knows your case best. Regards, 

Hello, An internal bra combines suture plication of the capsule with absorbable mesh or biological sheeting, to more reliably reposition the implants into their proper position. 

Internal sutures to reshape the pocket for an implant is called a capsulorrhaphy, and it is only as strong as the scar capsule. It doesn't matter what type of stitches are used if the capsule is too thin or weak. An internal bra is the addition of a layer of support, most often with Galaflex mesh or an ADM such as Strattice.

Dear mayo90,
you are right, internal bra sutures are used in order to keep the implants in place and prevent their migration out of pocket. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

so you must clarify what this internal bra does and what sutures are used.  Regardless, for straightforward augmentations, no internal bra of any sort is needed.  If you are having a mastopexy, deep sutures are placed routinely but does that constitute an 'internal bra' as your surgeon espouses?  So find out what suture is used and you can confirm on-line or here whether you are being told the whole truth and nothing but the truth vs some marketing strategy to make one stand out from the rest.

Internal Bra Suture
Surgical Technique is used to Customize the Implant Pocket to the Specific
Diameter of the Implant Chosen for a Natural Breast Shape with Projection and
Cleavage
I create an
underwire bra conformation with sutures along the natural lateral breast fold
and the inframammary fold.  Imagine a tailor creating a Dolce and
Gabbana-type corset design along the outer breast and long the normal under
fold of the breast.  This will hold the chosen implant on the top of the
chest and the implant will fit in the pocket like a hand in a kid glove.
 I also use it to create definite cleavage that will be maintained over
time as the lateral sutures of the internal bra will prevent outward movement
of the implant, as this lateral implant drift will widen or truly
eliminate "cleavage".  I use this technique on all of my
breast implant redo's (revisions of patients referred to me with
contractures, asymmetries, rupture, and other problems that require re-operation), which are
a large part of my breast implant practice. I also use this technique on first time breast
augmentations when the skin brassiere is stretched and not ideal. Like my
professor said, "anyone can do the easy ones." I love the challenge
of breast augmentation and the internal bra is a staple of natural and
long-lasting breast implant surgery.

Thank you for the good question. Semantics can be confusing; for example, the "internal bra" terminology has been used differently by different surgeons.  In our practice, the "internal bra" refers to maneuvers utilized ( generally during revisionary breast augmentation surgery) to better support the breast implants in appropriate position.  These maneuvers may include adjustment of the breast capsules (capsulorraphy)  and/or the use of acellular matrix or  biosynthetic mesh.  The "internal bra" can be especially helpful when patients are experiencing breast implant displacement problems (such as bottoming out or lateral displacement).   
My best advice: select your plastic surgeon carefully. This will be a much more informed decision compared to exactly what type of "material" is used (if any) during the revision breast operation. Make sure that he/she has significant experience achieving the types of outcomes you will be pleased with. Then, communicate your concerns and goals carefully, as well. Working together you will come up with a good plan to achieve your goals.  
 
 I hope this helps. Best wishes.

Best to post some photos.The capsule that is created when an implant is placed can be too soft, too big, too tight, not open enough etc etc. This leads to support and shape changes. For too big capsules correction would be to suture the capsule (capsulorraphy), a neopectoral pocket (ie - create new submuscular pocket), site change - over to under or under to over, use of mesh like Galaflex or acellular dermal matrix (ADM - like Strattice or Alloderm) or a combination of above. For malpostions some docs like to just use sutures for support. I am a huge fan of mesh and ADM in revisionary breast surgery. I have never heard of sutures that dissolve over 10 years
