Anatomical or Round - Which Has Better, More Natural Movement?

Hello! I am a very petite 32AA and I want to achieve a C cup. Because of my fragile frame, many surgeons have suggested me to get silicon tear drop / anatomical implants because i dont want the stuck on look. Do anatomical implants move like real breasts when you lie down or which kind of implant is the most "real" thing you can get?

Breast Implants - Anatomic?

How Anatomic are
Anatomic Breast

There are many choices that the prospective breast implant patient has to make. Aside from who will be the surgeon, the patient has to think about what size implant she wants, what style, location (above or below the muscle), and which incision. The following discussion explores one of the most basic decisions concerning the implant style: Round or Anatomic?

Not so with the anatomic or "teardrop" implant. This implant was originally intended for use in breast reconstruction patients (i.e., after a mastectomy). The natural breast, of course, is not round. Instead, it is conical or teardrop-shaped, with a gentle slope at the top and more of the breast in the lower half. The teardrop implant, therefore, most closely mimics that shape and is ideal for total breast replacement. Unlike the round implant, the anatomic implant has only one correct orientation and must be lined up exactly right; if it is rotated even a few degrees it will not look right.

What about the typical cosmetic breast enlargement patient? While there are different opinions and preferences on this matter, two recent studies have shed some interesting light. At first glance, the anatomic implant makes the most sense and, indeed, it is the first choice of many surgeons. However, aside from the fact that it only comes in a textured form (and for many reasons, many patients and surgeons prefer a smooth implant - which is a topic for another time), on closer examination it may not prove to the the best choice. First of all, most patients who have even a little breast tissue already have more of it in the lower half of the breast (i.e., a little sagging). Adding more volume to that part of the breast actually compounds the "problem" rather than compensating for it. So a round implant, that has relatively more of its volume in its upper half (than an anatomic implant) actually does a better job of putting more where you need it more, assuming you'd like more of a balance.

What about that round, ball-like look that everyone hates? Well, first of all, you normally get that when you have too big of an implant for the space in question; i.e., when a woman has chosen an implant that's a little too big for her chest. It's hard not to "go for it" when you're choosing an implant size, but it may be well worth being a little conservative in this regard. After all, it's much easier to make yourself look a little larger for selected occasions than it is to make yourself look a little smaller. One woman who felt she had gone a little too big later told me that she looked great in evening wear and lingerie, but for just hanging around the house in sweats, it was a bit much. Secondly, not everyone hates that look; some people actually like it (assuming it's not too extreme).

There's more. The above discussion is based on the implants shape when they're sitting on a table. What happens in a real-live woman? This question was addressed in two recent studies* and the impressive results confirm what many surgeons have believed for a while. In a patient, a round implant often behaves more anatomically than an anatomic implant! A number of women with implants were examined radiographically (i.e., using x-rays) in both the standing and lying positions. They found that when women are standing, the implants are similar. The anatomic implant assumes an anatomic (teardrop) shape. This is not surprising, but what is surprising is that so does the round implant! When a woman is standing, gravity works on the implant to pull a little more of it down and, from the standpoint of x-rays both implants are relatively teardrop-shaped and therefore anatomic.

So what happens when a woman lies down? Well, the anatomic implant remains "anatomic;" i.e., it maintains its teardrop shape. The problem is, you don't always want that when you lie down. Natural breasts fall to the side when a woman lies down, so, ironically, the anatomic implant is less anatomic when a woman is lying down. And what about the round implant? Because it has less of a framework than the anatomic implant (which is what keep it anatomic), the round implant can, once again, respond to the forces of gravity and more closely mimic the natural breast. They found, quite remarkably, that the round implant falls to the side much more than the anatomic.

[In fairness, is should be pointed out that, with time, some women have had "dishing out" of their round implants (i.e., the become wider and flatter with time) to a greater extent than the anatomic implants do. Anatomic implants, however, because they're textured and have more of a framework, remain stiffer than many round implants, particularly smooth ones.

In sum, therefore, when you use the term "anatomic" you may need to be prepared to define it carefully. Do you mean anatomic on a flat surface like a table, or in a woman? In view of the above, one could definitely argue that the round implant is actually more anatomic than the anatomic implant!

I hope that this helps, and good luck,

I recommend Round Implants for Cosmetic Breast Augmentation

Anatomical (also called teardrop) shaped implants tend to be made firmer (this helps them maintain their shape), so they might not feel as natural as round implants which tend to be made softer. 

I therefore always use round implants for breast augmentation, even in petite, small breasted women. In such cases, the most important thing, for me, is to put the top half of the implant under the pec muscle to avoid the implant showing through and looking fake.

Having said that, I do sometimes use anatomicals for reconstruction after a mastectomy and I think this is where they are really good.

In any case round implants take on a teardrop shape when in the body - next time you get the chance, hold one by its top, let it hang down, and have a look!

The other big advantage is that if a round implant moves inside the breast, the  shape of the breast does not change. In fact, a round implant can flip back to front and still not be a problem often! This is not the case with teardrop implants. If these rotate there will be an unnatural fullness in one part of the breast depending on how the implant has turned.

Teardrop implants cost a lot more than round. This is therefore one of those situations where the more expensive option is not the better one.

So, there you have it, as far as I am concerned, round implants all the way!

Anatomical v/s round implants

In order to prevent an anatomical implant  from rotating,the surface is textured

Textured surfaces are thicker,do not move as naturally as smooth surfaced implants,require larger incisions to insert,and have a higher rate of seroma formation.

Even with the textured surface ,rotation can occur resulting in an abnormal appearance

My  patients that have had their textured implants replaced with smooth implants have immediatly noticed the more natural feel of the smooth implants

Anatomical vs. round implant

Anatomical implants are sometimes preferred in women with small breasts as they provide more projection for less volume and have less visible fullness in the upper part of the breasts. Round implants on the other hand, I feel, provide a more natural 'unoperated' look, provided you do not opt for a very large implant.

Anatomical or Round - Which Has Better, More Natural Movement?

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Thank you for the question. These days there are a variety of breast implants available; the variety of breast implant available raise a lot of questions from women considering breast augmentation surgery. Personally, I think that for most patients considering breast augmentation surgery, careful selection of plastic surgeon and careful communication of goals, far outweigh the specific type of breast implant utilized (when it comes to the success of the breast augmentation procedure).

Anatomical breast implants were designed to better simulate the natural breast shape; the problem with these implants is that if they shift or rotate, the entire breast will change shape as well. This change in breast shape may require further surgery to correct. Round implants, under the hand, can shift or rotate without changing the shape of the breasts. Overall, I find that beautiful outcomes can be achieved with the use of round saline or silicone gel breast implants for the vast majority of patients.

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 with 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 words such as “very natural” or "C or D 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 concerns) helps. Best wishes for an outcome that you will be very pleased with.


"anatomical" implants is a misnomer

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

it is not proper to call any implant anatomic - just as the "normal" breasts of different women vary greatly, so do their desired results -  there is no such thing as an anatomic implant.  the most important thing to convey to your breast implant surgeon is your desired result - he or she should be able to advise you whether that result is possible given your pre-existing anatomy.

Anatomical or round implants

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

It is not a hard and fast rule, but anatomical implants can give a more natural look in patients with small breasts like yourself.  This is because they have less fullness in the upper pole, which is what creates the so-called 'operated on' look.  The shape of the implant does not affect the way they feel and they may not move as much as a natural breast.

Round implants can achieve natural look

If you want more of a teardrop shape to your breast and have little of your own breast tissue, teardrop implants may be better. However, I have achieved great results with round as well and usually prefer it to teardrop. Ask your surgeon for their opinion

    There is not one superior implant for your shape and size.  Generally thin women who opt for larger implants no matter the type can look unnatural.   When an appropriate impant whether anatomic or round is selected for your frame they can both look and feel somewhat natural when placed in the submuscular plane.  I recommend your viewing many photos of women who have both types of implants so you can then select the look you prefer. Consult with an experienced surgeon whom you trust and can better guide you.

Anatomic verus Round Implants

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

As others have stated, I am not a fan of anatomic implants either, especially for primary breast augmentation.  Anatomic implants may have a place for reconstructive breast surgery.  However, in my opinion traditional round smooth silicon submuscular implants give the best results.  


Good Luck.
