Considering downsizing my 500cc, moderate plus, silicone implants. I am petite, 5'1, 110lbs, 34 A pre-op.

You may be able to just decrease the implant size by 150cc and do a small amount of capsule plication on the lower implant pocket to get the results you desire. There are several other options that you can do as well and please seek out a board certified plastic surgeon in your area. Good Luck!

It is certainly feasible to #downsize to smaller implants and also alter the positioning; if possible. However, decreasing is size may also require a Breast #Lift to to #tighten loose skin, better optimize the end result. Any #revision has risks of unhappy outcome or other complications. Also, the right implant for the revision is contingent on shape of body and your desired outcome.

Thank you for your question and photos. No, your implants do not look awful. I suspect they would be the "wish pics" of many patients, but if they feel too large to you and you don't like the look or feel of them you should definitely consider an implant exchange. If upper pole fullness is a concern shaped implants may be a good choice for you, but many women achieve natural looking breasts with round implants. The attached link will give you some examples of patient results with smaller implants.

Thank you for your question and posting appropriate pix. It does seem you would benefit from downsizing and pocket revision. I like switching to textured silicone gel implants to help with breast retraction. Typically recommended at least a 100cc reduction per side. 

If you are unhappy with the overall size, then you might want to downsize a bit.  The post-op recovery is often easier than after the first one.
