Breast
Reversing the Rules: When (and When Not) to Believe the Warnings About Breast Asymmetry
Dr. Smith distinguishes breast volume differences from nipple, fold, and chest-wall differences, explaining why each can require a different surgical plan.
In this episode.
Episode summary
The episode examines the warning that implants can make breast asymmetry more noticeable. Dr. Smith distinguishes positional differences—such as nipple height, breast-fold height, or chest-wall shape—from a difference in volume alone.
His volume example starts with breasts of 200 and 220 cubic centimeters. Adding 250 cubic centimeters to each produces 450 and 470. The absolute difference remains 20 cubic centimeters, while the difference relative to the smaller breast falls from 10% to about 4.4%. The example illustrates proportional change; it does not promise that every patient will perceive the result as symmetric.
Three patterns guide the discussion: deflation after breastfeeding, congenital or tuberous anatomy, and chest-wall asymmetry. Dr. Smith explains how examination and Vectra 3D imaging inform choices among identical implants, different implant dimensions, a lift, fold adjustment, or fat grafting. The recording repeatedly returns to diagnosing the type of asymmetry before choosing an implant.
Questions this episode answers
Can identical implants reduce a volume difference?
They can reduce the proportional difference in the example discussed, while leaving the absolute difference unchanged. The recording distinguishes that mathematical effect from a promise of perfect symmetry.
Why does nipple or fold position need separate attention?
Adding equal volume does not move a lower nipple or correct a mismatch in breast-fold height. The episode explains why positional differences can require a different part of the surgical plan.
How does tuberous anatomy change the discussion?
Dr. Smith describes constriction, base-width differences, and fold position as structural issues that cannot be assessed as a simple volume difference alone.
What is the role of 3D imaging?
The recording describes measuring volume differences and comparing simulated implant plans so that the likely proportional correction and remaining differences can be discussed before surgery.
Original show notes
Manhattan plastic surgeon Dr. Darren Smith explores the "volume exception" in breast asymmetry, explaining why traditional surgical warnings are often correct—but can also be completely backward depending on your anatomy. He walks through the three primary patterns of asymmetry to show how math and 3D imaging dictate the perfect surgical plan.
What you’ll hear in this episode:
The Half-Truth of Textbooks: Why the common warning that implants always magnify asymmetry is true for position but false for volume.
The Volume Exception: How the "arithmetic of proportions" can shrink a visible 10% volume difference down to a negligible 4.4% using identical implants.
When the Warning Holds True: Why implants actually make positional issues, like uneven nipple heights or creases, more visible to the eye.
The Post-Nursing Pattern: Why deflation after breastfeeding is the textbook case for using identical implants to restore symmetry.
The Tuberous Deformity Trap: Why congenital asymmetry requires a specialized tissue release rather than a simple volume fix to avoid worsening the appearance.
Chest Wall Dynamics: How rib cage flares or a sunken sternum create "recessed" breasts that require different implant profiles to correct.
Landmarks vs. Ratios: Why the human brain focuses on nipple position even after the volumetric math has been solved.
Visualizing the Math: How 3D imaging at the consultation stage sets realistic expectations by simulating identical versus different-sized implants.

[00:00] Almost every plastic surgeon will tell you the same thing. If your breasts are uneven, a breast augmentation is going to make it worse. That's what I was taught. That's what's in the textbooks. And for most kinds of asymmetry, it's true. But there's one kind of asymmetry where that teaching is completely backwards. Where the same implant in each breast actually makes you more symmetric, not less. And nobody explains this to patients before surgery. So today I want to show you the math. Walk you through the three types of asymmetry I see in my Manhattan practice. And tell you exactly how I decide whether someone needs identical implants, different implants, or implants plus a lift.
[00:51] I'm board certified New York City plastic surgeon Dr. Darren Smith. And this is plastic surgery before and after. Your source for the real deal about plastic surgery procedures, news about trends in aesthetic medicine, and candid sessions with industry insiders. We hope you enjoy today's episode. Before we get into that, I also wanted to encourage everyone to check out our new podcast, Plastics and Peptides, which we are doing in conjunction with our super co-host, Dr. Amanda Kahn. She is a top longevity medicine specialist, and it's a really cool show. A great place to learn about all things longevity and the intersection of longevity with aesthetic medicine and plastic surgery.
[01:31] Make sure you check that out. The link is in the show notes for this episode. And now, let's get into today's episode. Here's the standard warning you'll hear at most consultations. Implants magnify asymmetry. You'll hear it from me too, because most of the time it's correct. If your nipples sit at slightly different heights, an implant doesn't move the nipple. So that one centimeter difference you had before surgery, it's still a one centimeter difference after. But now it's sitting on a bigger, more visible breast. The eye picks it up more, not less. Same thing with the inframammary fold. That's the crease where the breast meets the chest.
[02:11] If one fold sits higher than the other, the implant amplifies that mismatch. Same with rib cage asymmetry. Same with a chest wall that flares on one side. So for positional asymmetry, nipple height, fold height, chest wall, the warning is real. Implants make it worse. But volume, volume is the exception. And this is where the math flips. Let me show you why. Say one breast has 200 cubic centimeters of native tissue, and the other has 220 cubic centimeters. That's a 20 cubic centimeter difference. In percentage terms, the right breast is 10% bigger than the left. On an A or B cup, you can see that. Patients notice it.
[02:56] They know which bra cup fills out more. They dress around it. Now watch what happens when we add the same implant to each side. Left breast is now 450 cubic centimeters. Right breast is now 470 cubic centimeters. The absolute difference is still 20 cubic centimeters. That didn't change. And it can't, because we added the same volume to each side. But the percentage difference dropped from 10% to 4.4%. That's not a surgical trick. That's arithmetic. The numerator stayed the same. 20 cubic centimeters. The denominator got bigger. The ratio shrunk. A 20 cubic centimeter difference against a 200 cubic centimeter breast is something you can see across a room.
[03:44] A 20 cubic centimeter difference against a 470 cubic centimeter breast, covered by skin and soft tissue and clothing, most people will never notice it. Not the patient's partner. Not the patient most of the time. Once the swelling resolves. This is the part of the conversation that never makes it into the standard patient-facing literature. Implants magnify asymmetry gets repeated as a blanket statement. When what's actually true is, implants magnify positional asymmetry and proportionally shrink volumetric asymmetry. Two opposite effects collapsed into one warning. So why does this math only work for volume? Why doesn't it work for nipple height or fold height? Because volume is additive in a way position isn't.
[04:31] When I add volume to a breast, I'm growing the denominator. The ratio changes. When I add volume to a breast with a nipple that sits one centimeter lower than the other side, the nipple is still one centimeter lower. The implant didn't move it. If anything, it's more visible now because everything around it got bigger while that one centimeter offset stayed fixed. So positional asymmetry needs a positional fix. That usually means a lift on one side or an internal adjustment to the fold. Or, if the anatomy calls for it, implants of two different sizes. In my practice, almost every asymmetric breast patient falls into one of three patterns.
[05:13] And which pattern you're in determines the plan, not the size of the difference alone. The first pattern is post-nursing deflation. A patient finishes breastfeeding and one breast just involutes more than the other. Ends up smaller, softer, more deflated. The nipples are usually in the same place. The folds are usually in the same place. The only real difference is volume. This is the textbook case for the volume exception. Identical implants on each side. Proportional correction. You don't need a lift unless the skin envelope is significantly loose. And if there's a small residual difference the patient wants tightened up further, fat grafting can act as a fine-tuning adjunct.
[05:56] This is, honestly, one of the most satisfying cases to do. The math works in the patient's favor, the surgery is straightforward, and the result looks the way the pre-op plan predicted. The second pattern is congenital. Asymmetry that was there from puberty. The most important version of this is tuberous breast deformity, which has a specific anatomy. A constricted lower pole, a narrow base width, and often a herniated areola, where the tissue pushes forward into the nipple. This is not a volume exception case. If I place identical implants behind a tuberous breast on one side and a normal breast on the other, I'm going to make the asymmetry worse, not better.
[06:40] The tuberous side needs the constricting tissue released. The fold often needs to be lowered, and the implant dimensions on that side usually need to be different from the other side. If anyone tells you that you have tuberous anatomy and the plan is identical implants, get a second opinion. That's not the right operation. The third pattern is chest wall asymmetry. The breast volumes might actually be similar, but the chest wall underneath isn't. One side of the rib cage projects forward more than the other, or there's a pectus excavatum where the sternum sinks in. Or a rib flare on one side. When the chest wall is asymmetric, the breasts sit at different depths in space, even if they're the same size.
[07:26] One side looks more forward, one side looks more recessed. And the volume math doesn't help here, because the problem isn't volume. For these patients, I'll often use implants with different projections on each side. Not different volumes necessarily, but different profiles to compensate for what's happening behind the breast. Sometimes that's combined with fat grafting to camouflage the chest wall contour itself. Now, I want to tell you something that most surgeons won't say on camera. Going from a 10% difference to a 4.4% difference is a mathematical win. It is not always a perceptual win. If you've spent years focused on the fact that your right breast is bigger than your left, you know exactly which one it is.
[08:12] You've dressed around it, you've adjusted your bra for it, your brain has a landmark. After surgery, the percentage difference is smaller. The absolute difference, those 20 cubic centimeters, is still there. And some patients, especially patients who've been hyper-aware of their asymmetry for a long time, will still track that absolute difference. They'll still know which breast is the bigger one. Because the brain doesn't do ratios, it does landmarks. This is why the pre-op conversation matters as much as the measurements. If you walk into surgery expecting perfect symmetry and you get proportional correction, the math won. But your experience of the result might not. I'd rather a patient walk in understanding exactly what the surgery can and can't do than walk out surprised.
[09:04] That's the whole reason I use 3D imaging at consultation. So the numbers become visible before we're in the operating room. So here's how the decision actually gets made in my practice, in order. First, I look at nipple position, fold height, and chest wall symmetry. These are the asymmetries that augmentation will amplify, so they drive the plan. If these are off, we're probably talking about a lift on one side, or a fold adjustment, or asymmetric implants. Second, I measure volume. Physical measurement plus Vectra 3D imaging, which gives me an objective volumetric scan of the chest. If the volume difference is modest, roughly under 15 to 20 percent, and the nipples and folds are symmetric, the volume exception does most of the work.
[09:53] Identical implants shrink the proportional difference and we're done. Third, I pick the implant. Identical, when the asymmetry is volume only and modest. Asymmetric implants when the volume difference is larger. Implants plus a lift when nipple position is the dominant issue. The sequence matters. If you pick the implant first, and then try to correct the asymmetry around it, you've already limited your options. If you diagnose the asymmetry first, and fit the implant to the plan, the result is cleaner. And the 3D imaging piece is worth mentioning because it lets patients see the exception. We'll scan your chest, the software quantifies the volume difference, and then we can simulate identical implants versus a 25 cubic centimeters or 50 cubic centimeters differential side by side.
[10:45] The math stops being abstract. You can see the proportional correction. You can also see the small absolute difference that will persist. Expectations get set in the room, not in the recovery suite. One last thing. If you've already had a breast augmentation with identical implants, and your asymmetry looks worse than it did before, that almost always means the original asymmetry was positional, not volumetric. The implants amplified a nipple position or fold height mismatch that identical volume couldn't fix. The revision plan depends on which component got missed. Sometimes it's downsizing or upsizing one implant. Sometimes it's an internal fold adjustment. Sometimes it's a unilateral lift. The diagnosis comes first.
[11:33] Same sequence, just in reverse. So does breast augmentation make asymmetry worse? For nipple position, fold height, chest wall, yes, usually. For pure volume, no. The math runs the other way, and for a lot of patients, that's the entire answer. If you're someone who's been told your whole life that implants would just make things more uneven, and what you actually have is a volume difference with symmetric nipples and folds, that standard advice might not apply to you. It's worth getting measured before you accept it. If you want to talk through your specific anatomy, my practice is at the Ritz Tower on East 57th Street in Manhattan.
