Is 400cc too big for my petite body? I'm 5'1"

hello thank you for your question and provided information as well;..based in your question its difficulted evaluate your case if the question dont have a picture, its recommended to get a consultation in personal with a plastic surgeon.

Hi AleSummer,Just be sure you use narrow based implants, because you are so petite.  A 400 is getting up there for you.  See below.  Here are a few tips for you because this is perhaps the hardest decision for a patient to make, as well as the surgeon.  Also see the video attached to my answer.  We spend up to two hours for our BA consults to be sure there is careful communication. We do a full exam in front of a full-length mirror taking six exact measurements.    We put your photos on a large computer screen for imaging, and go over your “ideal-size” photos. We then save this information to your password protected “web account.”

     First and foremost the implant should fit the dimensions of your breast and tissue cover.  Balancing the implant to your over-all body shape and tissue cover is essential.    The main thing is to have the diameter of the implant fit the diameter of your breast "foot-print".  Higher profile implants tend to have a smaller diameter.  Higher is really a marketing term, but often translates into the same volume implant with a narrower base.  Saline implants actually tend to decrease in diameter as they are inflated!  The average size chosen over our last 7,000 breast implants was “350cc”.  BUT, 90% of our patients tell us they wish they were bigger a year after BA.  (We will see you every year for routine checks at no charge.) It’s like your mind incorporates the "new you" into your own self-image over a period of time. Cup size estimates can be misleading, but I generally advise patients that they will experience an increase of approximately one cup size per 200 cc.  You can try on implants in the office by placing them into a special bra.  The implant is also flattened somewhat when under the muscle, so it is a good idea to bump it up a bit. Approximately 1-ounce (25cc) is added to the final volume to account for flattening of the implant in the partial sub-muscular pocket.  Once you decide on a size you like, then add on 25cc, because in real life the implant will be flattened slightly by your tissues.  Multiple measurements need to be taken to fit an implant to your exact anatomy.  Have your surgeon's office show you the charts of the implant dimensions for the various profiles of silicone and saline from the manufacturer.  Then you and your surgeon can piece together the puzzle by matching your measurements, with your wishes, versus your tissue cover and the available implants to arrive at a surgical plan.  Keep in mind larger implants tend to have more problems over the years.  Since silicone implants wrinkle less than saline implants, they might be your best bet.

     You can also approximate this at home by measuring out an equivalent amount of rice placed into a cutoff foot of old panty-hose, and put this in your bra.  Wear this around the house for a while, and see what you think.  Implant size must square with assessments of tissue cover, breast diameter, and chest wall width.  Multiple measurements of your chest wall are taken (seven in total).  Implant size selection has been an issue of much discussion.

     Therefore, I use a wide variety of methods, but the implant size is always established preoperatively.  Also, patients are advised to bring reference photos demonstrating their ideal size and shape.  A photo album of patient pictures is maintained to assist them.  These photos ultimately help in determining where the implants will be placed, since they can be shifted inside (to provide more cleavage), to the outside, up or superiorly, and down or inferiorly during surgery.  In determining the final size selection, I always place the highest priority on the preoperative measurements and potential tissue cover.  Finally, your verbal requests are factored into the analysis.

     We use the quick-recovery approach, so click on the web reference link below to have this explained and you can see the list of Quick-Recovery (Flash-Recovery or Rapid-Recovery) Breast Augmentation articles from peer-reviewed surgery journals.  It is a surgical procedure that uses special instruments and techniques to minimize tissue damage and avoid touching the ribs. It causes far less trauma to surrounding tissue than traditional approaches, and it dramatically reduces pain and recovery time. In published studies of BA patients, 95-percent of women interviewed after the procedure returned to normal daily activities within 24-hours. Quick-recovery BA is not a “gimmick.”  These specialized techniques, which actually speed recovery and get you back to your daily routine, kids and work, are published in our plastic surgery journals.  Because these PS journals are “peer-reviewed” and edited, they are the gold-standard in our field as being valid science. Therefore, these are sound techniques, not marketing hype. 

     Be sure to see only a board certified plastic surgeon (by ABPS - The American Board of Plastic Surgery) who is a member of ASAPS (The American Society for Aesthetic Plastic Surgery) and or a member of ASPS (The American Society of Plastic Surgeons).  Also, ask if the PS has an established, high volume breast augmentation practice, performing several hundred breast augmentations each year.  Be sure the PS has been in practice for a while, about 20-years might be a good gauge.  Does the PS offer all three incisions?  Discuss the implant type (gel or saline), shaped "gummy bear" or non-shaped, smooth or textured, implant pocket (over or under the muscle) and the "quick-recovery approach."  Ask to see their before and after photos if you didn’t see any on their website.  If they are experienced, they should have several 100 breast implant patients for you to view.  I would also recommend that your doctor offer you the chance to talk to past patients who would be happy to discuss their experience with you.  You need to feel comfortable, so make sure the environment is safe as in an accredited surgery center.  Also, ask a prospective surgeon if he or she has ever published journal articles in professional peer-reviewed journals, which they can provide you.      

All the best, “Dr. Joe”

 

 

Patients often think in terms of cup size when considering augmentation. Unfortunately, devices are sized in terms of milliliters (cc) of volume. This can lead to some confusion when sizing. Additionally, it is important to remember that cup size itself is not standardized with variations from one manufacturer to another. Unfortunately, as many women can attest their cup size in an industry leader such as VS is not necessarily transferable to another brand.
Another point which is often under appreciated is that of anatomy and starting point. Any implant will add volume to the volume which is already present. The implant is additive. A particular volume will not necessarily confer the same cup size to different patients (often times it will not even confer the same cup size to different breasts in the same individual...remember they are "sisters" not "twins"). 
A general rule of thumb is that 125cc can represent somewhere between 1/2 to a full cup size increase. Smaller volume differentials (25-50cc) are typically less consequential representing a volume change of less than a shot glass. However, I have found these numbers, at least anecdotally, to be of little help. Patients often present with notions/goals which do not correlate with these sorts of sterile volumetric assessments.
When sizing patients, there are a number of useful tools including:
-3D imaging (has the added benefit of offering a volumetric analysis of the pre-operative breast)
-Breast sizers (rice bags)
-Goal photos
I also recommend that patients commit to a particular look rather than a cup size. Once a patient settles on a look that pleases them the overall cup size increase becomes less relevant.The key to obtaining a natural result is to stay within the parameters defined by your BWD. This will ensure that you avoid the dreaded "fake" look. 
With regards to your specific question, "too big" is a relative question. The best advice is to respect your BWD. What may seem "too big" to one may not to another. It is important to remember small girls rarely have large breasts. Oversizing can lead to a mismatch of frame which is often a hallmark of augmentation and the opposite of "natural" 
As always, discuss your concerns with a board certified plastic surgeon (ABPS).
