I appreciate your question.

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.  Other than that, you should choose the implant based on volume, not on the dimensions of the implant. You should choose a board certified plastic surgeon that you trust to help guide you in this decision.  

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 liquid silicone (less cross-linked), if this implant should rupture, it will leak only into the scar capsule formed around the implant but may cause some discomfort or implant distortion.

Anatomic gummy bear implants might be a good choice to give you volume.

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.

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.

The best way to assess and give true advice would be an in-person exam.

Please see a board-certified plastic surgeon that specializes in aesthetic and restorative breast surgery.

Best of luck!

Choosing breast implants

Thank you for your question. Breast implant selection is an important process and requires good communication between you and your surgeon. Typically, breast measurements are initially obtained to provide an initial guide to implants appropriate for your chest. It's then advised that you try different sizers in a normal bra with a tight t-shirt to get an idea of what your breasts would look like. It's important to focus on the look that you want and not overly focus on a specific cup size or implant size. Be sure to consult with an experienced board certified plastic surgeon. Good luck!

Proportion in Breast Augmentation

"Proportion" is a very subjective term, especially when breast size is the concern.  The key for you will be to determine what looks proportional to you.  Your plastic surgeon will help you make this determination with a variety of techniques.  3D breast imaging can be very helpful in helping you select the look you  desire.  Sizing bras with/without a t-shirt can also aid in visualizing the result you are looking for. Focusing on the look you want is much more helpful than looking at different shapes and volumes of implants.

If you're thin with a small waist and thin torso, what size and shape implant do you get if you want to be in proportion?

The best cosmetic result in any particular breast augmentation patient depends on a variety of factors, including: your individual anatomy, realistic expectations, a thorough discussion with the plastic surgeon about the options, and an understanding of the pros and cons of any particular implant choice. Proper sizing is not just about the number of cc’s. or what style implant. The thickness of your tissue, breast dimensions which include the width, height, and projection, as well as chest wall width all need to be considered when choosing an implant. Trying on implant “sizers” of various shapes and volumes while wearing a tight t-shirt, bra, or bathing sit at a preoperative visit will help you and your surgeon choose the optimal implant.

Keep in mind that following the advice from a surgeon on this or any other website who proposes to tell you exactly what to do without examining you, physically feeling the tissue, assessing your desired outcome, taking a full medical history, and discussing the pros and cons of each operative procedure would not be in your best interest. I would suggest that your plastic surgeon be certified by the American Board of Plastic Surgery and ideally a member of the American Society for Aesthetic Plastic Surgery (ASAPS) that you trust and are comfortable with. You should discuss your concerns with that surgeon in person.

Breast augmentation

Thank you for your question.

I would recommend that you schedule a consultation with a board certified plastic surgeon so they can perform a physical examination and take measurements so they can recommend the best implant type/sizes for your body. There are 3D simulators that can show you what you would look like with different types of implants and different sizes, this can be helpful when trying to decide what size would achieve your cosmetic goals. At my office, I use high profile Sientra implants to create a round full result that looks natural, giving you the result that you want. Additionally, i use Crisalix which is a virtual reality device that will allow you to view different sizes of implants and pick which best suits your desires.  As the only board certified plastic surgeon in Pittsburgh offering this virtual reality imaging system, we have a 100% satisfaction rate.  Crisalix is truly a unique experience for our patients as they can view themselves using virtual reality goggles and can instantly visualize their own breasts changing in size and shape with all of the various brands, sizes and shapes of breast implants.  Thus, our patients leave the consultation feeling confident with the size of the implant they chose. 
Best of luck in your endeavors!

If you're thin with a small waist and thin torso, what size and shape implant do you get if you want to be in proportion?

One of the most important factors to consider when choosing an implant is your breast width. Therefore, a petite woman has fewer options. That is why I prefer a high profile implant. It allows for more volume and projection without getting too wide for your breast. Good luck!

Thin with a small waist and thin torso, what size and shape implant do you get if you want to be in proportion?

Thank you for the question. Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, and computer imaging) will be critical. 

Having said that, for most patients with a petite frame and anatomic starting point, I recommend the use of round silicone breast implants placed in the sub muscular (dual plane) position.   You will find many similar/representative examples on the attached link.

Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:

1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.

2. Have a full discussion and communication regarding your desired goals we have time for a you their stuff's's homewith your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 

In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of know words such as “natural” or "B or C cup” etc means different things to different people and therefore prove unhelpful.

Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.

3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.

I hope this (and the attached link, dedicated to breast augmentation surgery for petite patients) helps. Best wishes for an outcome that you will be very pleased with. 

Implant size

The best way to pick implant size is based on your breast and chest width and not the volume. As the implants get bigger, they get wider. When the width of the implant fits the width of your chest, it will look nice and fit your frame. If the implants are too small, you will have a gap between them and they may look too far apart. If they are too wide, they will make you look top heavy as they may be too wide and stick well out past the sides of your chest. There are ways to get a bigger or smaller look.This can be done by picking a different implant profile. The higher the profile, the narrower the base width of the implant. If someone has a very narrow chest and wants to be big, they should consider a higher profile implant. If someone has a broad chest and they do not want to be too big but want to avoid the gap and still have cleavage without projection, they should consider a lower profile implant such as a moderate. There are options in between these such as the moderate plus. I prefer the underarm approach so there is no scar on your breast. The new silicone is the only way to go as far a rippling as the new silicone ripples much less than saline, especially in the larger implants. I personally prefer the smooth round implants under the muscle placed through the under arm to give you the most natural look and feel. This also leaves no scar on your breast.
