Is 500cc high profile silicon placed over muscle a good idea for me? (photos)

Breast implants alone, even in the supra pectoral space, will not correct the four major problems associated with droopy breasts:1.  the areola are normally too big - you match that category2.  the areola are too low on the breast mound - this is certainly true of your breasts3.  your breasts are hanging on the chest wall - that's also true4.  you have no fullness in the upper quadrant - while the implants will give a bump of tissue in the upper portion of your breasts, they won't look attractive or natural unless you have an associated breast lift.

 Thank you for the question and pictures. Your pictures demonstrate breasts ptosis and you will benefit from breast lifting surgery. Breast augmentation surgery may also be helpful if you wish to increase breast size and/or change brush shape further. For some patients the necessity of additional scars associated with breast lifting is a “dealbreaker” ; for these patients it is better to avoid breast surgery altogether.
 On the other hand, many patients (If properly selected and who are doing the operations at the right time of their lives  psychosocially) accept the scars associated with breast augmentation/breast lifting surgery as long as they are happy with the improvement in contour, size, and symmetry. This acceptance of the scars is the essential “trade-off” associated with many of the procedures we do in the field of plastic surgery.
  Patients who are considering breast augmentation/lifting surgery should understand that this combination surgery is significantly more complex than either one of the procedures done separately. In other words, the combination breast augmentation / mastopexy surgery differs from breast augmentation surgery alone in that it carries increased risk compared to either breast augmentation or mastopexy surgery performed separately. Furthermore, the potential need for revisionary surgery is increased with breast augmentation / mastopexy surgery done at the same time.  This revisionary rate may be as high (or higher) than 20%. Patients should be aware of this higher revisionary rate;  obviously, the need for additional surgery, time off work/life  considerations,  and additional expenses  our “factors” that should be considered before undergoing the initial operation.  
 Personally, I find that the breast augmentation/lifting procedure to be one of the most challenging  of the breast operations I perform, even compared to somewhat complex revisionary breast surgery. On the one hand,  when performing breast augmentation/lifting surgery we are increasing the breast  size with breast implants;  on the other hand, we are reducing the breast “envelope” in order to achieve the breast lift. These two “forces” must be balanced as perfectly as possible in order to achieve the desired results. Removing too much skin/ breast tissue is problematic;  removing too little breast skin/tissue can also be problematic.  Remember also that patients presenting for breast lifting surgery and general have lost some skin elasticity/thickness making potential incision line healing problems and/or recurrent drooping/sagging important concerns to communicate.  The analogy I use in my practice is that  of a thinned out balloon,  being expanded with additional air; I hope that this analogy helps patients understand some of the issues at hand when performing the combination breast augmentation/lifing operation.
To achieve  a surgical result where the breast implant and breast tissue “come together” and behave like a single breast is one of my goals but can be difficult to achieve.  Essentially, we are trying to create a breast implant/breast tissue interface that feels and behaves as naturally ( as a single unit)  as possible. Generally speaking, making sure that the breast implant has some sub muscular and some sub glandular component ( dual plane)  and tailoring the overlying skin/subcutaneous tissue/breast tissue as precisely as possible over the underlying breast implant is key.
Despite these efforts, breast implants are after all a foreign body that don't necessarily stay where we wish they would;  therefore, breast implant related problems such as positioning ( too high, too low, lateral displacement etc.) can occur  and may be a reason for returning to the operating room for revisionary breast surgery.
I use a “tailor tacking” technique that allows a determination of what breast implant should be used to SAFELY produce the results the patient is looking for. This technique involves use of a temporary sizer and temporary “closure” of the overlying breast skin over the sizer. 
The use of the tailor tacking technique is very helpful.  Breast lifting involves removal of skin ( and tightening of the breast skin envelope)  while breast augmentation involves expansion of the breast skin envelope. These 2 forces are counteracting each other. Therefore, it becomes important to remove the appropriate amount of breast skin and to use the appropriate  size/profile of breast implants to balance these 2 forces appropriately and to allow for achievement of the patient's goals while minimizing risks of complications.  Again, despite these efforts, breast implant and/or tissue/skin complications may arise causing minor or significant complications.
 Generally speaking, it is difficult to achieve the “perfect” result with breast augmentation/lifting surgery, despite best efforts.  Patients should be aware of the complexity of this combination procedure, achieve REALISTIC EXPECTATIONS prior to proceeding, and understand that additional surgery ( along with the additional recovery time, stress, expenses etc) may be necessary in the short or long-term. Patients should understand that the results of the procedure will not necessarily match aesthetically the results of patients who have undergone breast augmentation surgery only.
For example, some patients who wish to maintain long-term superior pole volume/"roundness" may find that this result is not achieved after the initial breast augmentation/lifting operation.  An additional operation, possibly involving capsulorrhaphy, may be necessary to achieve the patient's longer-term goals ( with superior pole volume/roundness).  It is helpful if patients understand that this breast implant capsule used to provide the support for the breast implant is not present during the initial breast augmentation/lifting operation.  The capsule (layer of scar tissue) forms around the breast implant and may be a good source of supportive tissue during revisionary breast surgery,  Including correction of breast implant displacement/malposition problems ( such as bottoming out, symmastia,  lateral displacement etc).
 Potential risks associated with breast augmentation/lifting surgery include infection, bleeding, incision line healing problems, loss/change of nipple/areola complex sensation, and blood flow related issues  to causing skin or tissue necrosis.   Poor scarring,  pigment changes, areola/nipple asymmetry etc. are also potential problems. Again, patients may experience implant related problems such as encapsulation, leakage, displacement problems ( too high, bottoming out, lateral displacement, asymmetric positioning etc.), rippling/palpability of breast implants etc.  Patients may also be dissatisfied with breast size, shape, and/or how the  breast implants and overlying breast tissues “interface” with one another.    Occasionally, a breast implant may even have to be removed and the patient will generally be “implant free” for several months at least.  Obviously, this situation can be quite physically, emotionally, and psychosocially stressful to the patient involved.
Given the complexity  of the combination breast augmentation/lifting operation and the greater risk of revisionary breast surgery needed, there are good plastic surgeons who will insist on doing the procedures separately.
For me, if I see a patient who needs a great degree of lifting, who has lost a lot of skin elasticity, or  whose goal is a very large augmentation then I think it is best to do the procedures in 2 stages (in order to avoid serious complications). However, doing the procedure in one stage does increase the risks of complications in general and the potential need for further surgery. This increased risk must be weighed against the practical benefits of a single stage procedure (which most patients would prefer).


Conversely, if I see a patient who requires minimal to moderate lifting along with a small to moderate size augmentation (and has good skin quality), then doing the procedure one stage is much safer. Nevertheless, the potential risks  are greater with a 1 stage  procedure and the patient does have a higher  likelihood of needing revisionary surgery.
  I hope that this summary of SOME  of the issues surrounding breast augmentation/lifting surgery  is helpful to you and other women considering this procedure in the future.
