Are 300cc Silicone Breast Implants Too Big for a Petite, A Cup Woman?

If you are as small as you say, those are big implants. And by my taste,. high profile implants tend to look round and fake, and seem to cause an excessive amount of skin stretch, atrophy of breast tissue, and concavity of the rib cage over time. Of course that doesn't happen to everyone, but one cannot place highly projecting implants into tissue with impunity. There is a price to pay for stretching tissue beyond where it has ever been or is meant to go.
Assuming your base width is 10 cm, then the ideal starting size for you would be about 200cc. If you were loose or empty you would add some volume, and if you were tight or full it would be less than 200cc.
These numbers are based upon peer-reviewed and published data. It is data that has produced the best published results to date in terms of outcomes. If, on the other hand, achieving a certain size is more important to you than respecting your tissues, then you can go larger than that. But understand that there can be adverse consequences to your tissues.

That size does not seem too large based only experience.  If you tried on sizers and they looked good to you, that is the most important factor.

I appreciate your questionAfter performing hundreds of breast augmentations, I have found that the size of implant best for you is dictated by your chest wall measurements.  Once we determine that we can choose the profile based on what you want or need to achieve.  If you are seeking a natural look, then the diameter of the implant should be equal to or, more ideally, smaller than the width of your breast. The breast width is a measurement of how wide your breast is at the base, which should be measured at the level of the nipple. Choosing an implant that is smaller in diameter than your breast width will avoid the "side breast" fullness that is often associated with a more artificial appearance. Implants that are wider than this can be more palpable, fall more laterally overtime and also be more palpable. After that we will then choose the implant volume based on the measurements and also looking at any asymmetries you might have. You should choose a board certified plastic surgeon that you trust to help guide you in this decision. Bringing photos as well can help us to finalize, but please understand that these are of other peoples bodies and your results will probably be different.Silicone will give you a fullness at the top (upper pole fullness). Silicone implants come pre-filled with a silicone gel and are the softest implant available. They feel more natural, which makes them a good option for women with less natural breast tissue; but they require a larger incision. It may be more difficult to realize if this type of implant has ruptured, so it is important to monitor them with annual follow-up visits. Additionally, because this implant contains a more softer silicone (less cross-linked), if this implant should rupture, it may leak but only into the scar capsule formed. However, the newer silicone in these implants may not leak even when the implant shell is ruptured. Anatomic gummy bear implants might be a good choice to give you a more natural look. These highly-sought-after, anatomic implants offer a look that more closely resembles the natural silhouette of a breast, and, therefore, are a very attractive option for individuals seeking a natural-looking, aesthetic primary breast augmentation. Additionally, these implants are an especially excellent option for patients undergoing restorative or corrective breast surgery because they provide more stability, shape, and reduced incidence of capsular contracture. Compared to other types of silicone gel implants, the silicone in the cohesive gel implant is more cross-linked; therefore, should the implant shell “rupture,” it maintains its shape and silicone does not leak. Implants, indifferent projections. The easiest way to think about it is they called me in a low medium and high projection or profile. Most of the time I use the medium profile which gives people the best in terms of natural look as well as a little bit of projection. High profile implants are for someone that wants  A little bit more of a fuller look. Low profile implants are better for someone that really wants a minimal extremely natural augmentation. Depending upon the anatomic versus round implants there are also subtle differences  in terms of the amount of projection for each profile. During your breast augmentation consultation, you should feel the different types of implants available, and try on various implant sizers in front of a mirror to help you to get an idea of how you will look following the surgery. You should also bring pictures of the look you would like to achieve, as well as a favorite top to wear when trying on implant sizers. I also use a 3D imaging system to allow you to try on a variety of shapes and sizes. I prefer this method over adding volume due to implants being under the muscle.We will also discuss the possibility of needing a lift along with an implant. This will depend on the amount of ptosis (nipple position) as it relates to your breast, inframammary crease and chest wall. Needing a lift or not will also determine where to place the scar for the incision.  In some cases if the the breast and nipple is really ptotic (low) it might be best to stage the procedure by performing a lift first and then doing an implant at a second stage. This will also allow you to have a better understanding of the true size and shape of your breast.In order to limit pain from breast augmentation and speed the recovery process I offer patients Botox into their muscles as well as a long acting numbing medication called exparel. The best way to assess and give true advice would be an in-person exam.

It’s always difficult making
decisions about breast size without performing a physical exam or seeing
pre-operative pictures. In addition, the patients underlying anatomy and
personal preference for size and shape must be considered.

 

         Even when tremendous
care is taken pre-operatively to determine breast size, the final decision
needs to be made in the operating room by the surgeon. At this point, an
assessment can be made by regarding how the patient’s breast tissue interacts
with the breast implant. Occasionally, obtaining a specific size does not allow
the surgeon to meet the patients other aesthetic goals. For this reason,
locking into a specific size isn’t always a good idea. Results are often better
when a surgeon has the ability to make adjustments in the operating room.

 

         In your case, I
think it’s important to thoroughly discuss your aesthetic goals with your
surgeon. Make sure he has the latitude to do what’s best for you in the
operating room, so he can meet your aesthetic goals. It’s important that you
have an approximate idea of the breast implant size that you are considering,
but don’t become married to an absolute number.

I am very particular about the size of implants that I use. I never exceed the base width of the breast and I also don't use high profile implants. I realize this is a conservative position to take but I cannot accept the risks of permanently damaging the breasts from too large an implant or an implant with too much profile. Thus, I think that those implants are too big for you. I would advise a much smaller mid profile gel implant that fits to your base diameter.

Thank you for all the measurements.  It sounds that your size may be in the ballpark for your frame.  We don't have photos or an exam, which can also be important.  Plastic Surgeons all have different ways of selecting implants.  Our office favors base width.  Having said that, we also try and fit the implant choice with what the patient's goal is.  Often we have patients bring in photos so that everyone has a good idea of the goal.  

300 cc may be a very reasonalbe size for your body type. Sizers wll help determine the appearance and assist in the decision making process

Dear @sweet
You ask a very good question. The answers that have been posted give you a large range of choice....that is the precise answer! Choice. The size you would like to achieve will have some trade offs associated with it. If the implant is larger than your breast envelope will adapt to easily the result may be more 'fake' looking breasts and tissue atrophy over time. My role is to guide you in the size but in the end I will try to accomodate your wishes as best that i can. A 300cc implant may be on the large side- and still may not achieve a 'C' cup- but you may 'love' the result. If that is the size that looks good in a T-shirt or a bra then that is the range we would work with and attempt to use. The most 'natural' results will be attained with a breast implant that is similar in diameter to your breasts - the vertical and horizontal dimension may be changed in some cases.

It sounds reasonable but it really depends on what you're wanting your look to be. I use high profile implants in patients that are your dimensions because they are the only way to get that size in when you're so thin. Because you were pregnant, I'm hoping that your tissues stretched some and will accomodate these implants reasonably without having stretched beyond retraction (the taffy effect).
At first, these implants will look and feel tight. That's because you put a big implant under a small breast. it's clear to me that you are small, and that you know that you are small. It also seems clear that you know that these implants are nothing to scoff at.
Remember, what makes these look fake is when your breast tissue is tiny and the implants are huge. If you make a major exagerated change, then it will be a major exagerated augmentation (that's not the case with you I'm just making clarification for other readers wanting to make major exagerated changes). We could blog about this all day but only the plastic surgeon that examines you will be able to communicate clearly because you have to get the measurements properly and feel the tissue elasticity and general breast tissue strength.
Also, who is to say what 'fake' means. The only way I communicate that to a patient is my looking at a bunch of pre and postop photos with the patient and give my opinion on if I think it looks fake or natural. That way you can see what I think looks natural or not.
I recently had someone tell me "I want them to look fake but natural".
She may as well have said that because until you look at photos, it doesn't matter what you or your plastic surgeon actually mean .. each of you could be imagining a totally different look. Rememer, a picture is worth around 7000 words (for silicone BA).

This seems to be a reasonable size for you. A lot of patients ask whether a certain size will be good for them or not. The answer actually depends on what kind of result is desired.
Chances are a 300 cc high profile implant will create some fullness over the upper part of the breasts. This tends to create a more rounded look, which is not how a natural breast looks. That is okay. Many women like to have that fullness over the upper part of their breasts.
A natural breast is always a little empty over the upper part of the breasts. This is what creates the "tear drop" shape often referred to. If you truly wanted a very natural looking result, you would probably need a smaller implant.
Again, it all depends on what you want.
Having said all of this, the 300 cc high profile implant is perfectly fine if you want fullness over the top of your breasts.
