Reducing breast implant size. 36DD to 36C. Possible?

Of course this is possible. It may require some skin tightening and a pocket adjustment to accommodate the smaller implant, but it certainly is possible.  Consider switching to a silicone implant since they have a lower specific gravity and weigh less per cc.  Good luck!

At
size 36 each 200 cc’s of implant corresponds to 1 cup size change. To go from a DD to a C would require 400 cc
removal. If you remove that much volume,
it is likely that your breasts will droop.
I recommend a new technique called Implant Exchange with Mini Ultimate
Breast LiftTM. Using only a
circumareola incision it is possible to reshape your breast tissue creating
upper pole fullness, elevate them higher on the chest wall and more medial to
increase your cleavage. At the same
time, your implants can be exchanged for smaller ones. Aligning the areola, breast tissue and
implant over the bony prominence of the chest wall maximizes anterior
projection with a minimal size implant.
Small round textured silicone gel implants placed retro-pectoral since
they look and feel more natural, are more stable, less likely to ripple or have
complications needing revision. Implant
profile is irrelevant in the retro-pectoral position since the muscle
compresses it. This technique avoids the
ugly vertical scars of the traditional technique, maintains nipple sensation
and the ability to breast feed. Best Wishes,Gary Horndeski, M.D.

Your saline implants can be removed.  Your breast size will reduce but no one can say that you will go from a DD to a C cup.  The hope is that your breast size will reduce to give you proportion to your chest, waist and hips. Earl Stephenson, Jr, MD, DDS, FACS

You can always have your implants exchanged for smaller ones, and you may be able to get to a C cup.  However, you may also need a breast lift, if downsizing leaves you with excess skin. 

Thank you for the question.To best help you, a physical
examination or picture evaluation is required in order to determine
which procedure and technique will be best for your case.Dr. Campos
