Breast augmentation is often described as if it were a single procedure. It isn’t. It’s a set of decisions — about the implant itself, where it sits, how it’s placed, and what kind of scar it leaves — each of which shapes the outcome in ways patients don’t always realize until later.

The last decade has quietly changed the field. New implants, refined pocket techniques, and less invasive anesthesia options have expanded what’s possible for the right patient. Some of those changes are marketed heavily; others aren’t discussed enough. This article walks through the actual decisions you and your surgeon will make together, and what each one really means.

Why there’s no such thing as a standard breast augmentation

Every breast is different. Every chest wall is different. Every patient’s goals, activity level, and body type are different. A woman who runs and lifts weights four times a week has different considerations than a woman who wants a subtle change after breastfeeding. A narrow chest with thin overlying tissue calls for different choices than a broader frame with more natural breast volume to work with.

Cookie-cutter augmentation — where the same implant and the same technique are offered to almost everyone — is one of the main reasons patients end up unhappy, or in a revision operating room a few years later. The techniques described below aren’t a menu you order from. They’re variables in a decision that has to fit the person in front of the surgeon.

What follows is meant as a translation, not a recommendation. The right choice for you is the one that emerges from an honest examination and a conversation about what you’re trying to accomplish.

Silicone vs. saline — the real trade-offs

Both silicone and saline implants are FDA-approved and have long safety records. The choice between them is mostly about feel, incision options, and how a rupture — if it ever happens — would be detected.

Silicone gel implants feel much more like natural breast tissue. The modern cohesive gels hold their shape well and don’t behave like the older-generation implants that made silicone controversial decades ago. Most patients today choose silicone, and in thinner patients — where any implant edge might otherwise be visible or palpable — silicone is often the better answer.

Saline implants are filled with sterile salt water after they’re inserted, which means they can be placed through a smaller incision. If a saline implant ruptures, the result is obvious: the breast deflates within a day or two, and the fluid is safely absorbed by the body. Silicone ruptures, by contrast, can be silent — the gel stays where it is, and you may not know without imaging.

Because of that, the FDA recommends periodic MRI or high-resolution ultrasound screening for silicone implants to check for silent rupture. The current guidance is the first screening around five to six years after surgery, then every two to three years after that. Saline patients don’t need this surveillance.

Cost differs modestly — silicone implants themselves are more expensive than saline, which shows up in the overall surgical estimate. For most patients, the feel of silicone is worth the difference. For a smaller subset, the simplicity of saline and the ease of monitoring make it the better fit.

Placement options: subglandular, subfascial, dual plane

Where the implant sits relative to the chest muscle is one of the most consequential choices in an augmentation — and one of the least discussed with patients in plain language.

There are essentially three placement options in modern practice. Subglandular means the implant sits under the breast tissue but above the pectoralis major muscle. Subfascial is a refinement of subglandular — the implant sits under the thin layer of fascia that covers the muscle, which adds a bit of soft-tissue coverage without disturbing the muscle itself. Dual plane partially releases the lower edge of the pectoralis muscle, so the muscle covers the upper portion of the implant while the lower portion sits directly under breast tissue.

In my practice, most cosmetic augmentations are subglandular or subfascial. These placements preserve full chest muscle function, which matters more than patients often realize until after surgery. They also eliminate the phenomenon called implant animation — the visible distortion of the breast that happens when the chest muscle contracts over an implant placed underneath it. If you’ve ever seen someone flex their chest and watched their breasts move sideways or flatten out, that’s animation. It’s not subtle, and for active patients it can be a real quality-of-life issue.

Implant animation is one of the most underappreciated downsides of muscle-based placement. Patients often don’t realize what they’ve signed up for until they’re back in the gym.

Dual plane remains a valid choice for some patients — particularly those with very thin soft tissue over the upper pole of the breast, where the additional muscle coverage helps disguise the upper edge of the implant. It’s a compromise: some of the animation issue in exchange for softer transitions at the top.

Full submuscular placement — where the implant is completely under the pectoralis — is largely reserved for breast reconstruction, not cosmetic augmentation. It creates the most muscle disruption and the most pronounced animation, and offers little that a well-executed subglandular or dual plane approach can’t achieve for the cosmetic patient.

The Preserve technique — what it changes

Preserve is a subglandular technique developed with two priorities in mind: longevity of the result, and natural movement. Rather than dissecting a generic pocket for the implant, the surgeon creates a carefully sized space that protects the native breast tissue, preserves the nerves that supply sensation to the nipple and areola, and supports a more natural drape as the implant settles over time.

What patients tend to notice is that the breast moves the way a breast should. It shifts when they lie down. It softens with gravity. It doesn’t sit on the chest like a fixed dome. Because there’s no muscle interference, there’s no animation. Because the tissue planes are respected, nipple sensation is more reliably preserved than in techniques that require more aggressive dissection.

Preserve also pairs particularly well with the axillary (armpit) incision approach, which we’ll discuss next. The combination allows for an augmentation with no scar on the breast itself — something that matters more to some patients than others, but is genuinely difficult to achieve with other techniques.

It’s not the right answer for every patient. Very thin patients or those with significant breast asymmetry may need a different approach. But for the patients who are candidates, Preserve has meaningfully changed what an augmentation looks and feels like a year or five years down the road.

Incision choices: IMF, axillary, and periareolar

There are three commonly used incisions for breast augmentation, each with its own logic.

Inframammary (IMF) is the incision made in the crease under the breast. It’s the most common approach in the United States and remains a versatile, reliable choice. The scar sits in a natural fold and is generally hidden by the breast itself when standing. It gives the surgeon excellent direct access to the pocket, which is useful for larger implants, silicone gel implants, and revision surgery.

Axillary incisions are placed in the armpit, using the natural creases of the underarm to conceal the scar. This approach has become increasingly popular with the Preserve technique because it leaves the breast itself completely unmarked. There’s no scar in the crease, none around the areola, none anywhere on the breast. For patients who care about scarring — particularly younger patients or those who’ve had visible scars heal poorly elsewhere — this can be the deciding factor.

Periareolar incisions are placed around the lower edge of the areola, taking advantage of the color transition to camouflage the scar. It’s available in select cases, particularly when the areola is large enough to accommodate the incision. It offers direct access to the pocket similar to IMF, but carries a slightly higher risk of changes to nipple sensation and, in some studies, a higher rate of capsular contracture. It’s less commonly chosen today than in prior decades.

The right incision depends on your anatomy, the implant you’re choosing, the placement plan, and how much you care about where any scarring ends up. There’s no universally best answer — only the best answer for your case.

Anesthesia: general or sedation-only

Breast augmentation has traditionally been performed under general anesthesia. The patient is fully asleep, intubated, and monitored by an anesthesiologist throughout. It’s a safe, well-established approach that remains the default for most surgeons.

For patients who are candidates for the Preserve technique, there’s a newer option: sedation-only augmentation. The patient is deeply sedated but breathing on her own, without intubation. The surgeon still performs the full operation with the same precision, but the anesthesia burden on the body is significantly lower. Recovery from the anesthesia itself is faster, nausea is less common, and the grogginess that lingers for a day or two after general anesthesia is largely avoided.

Not every patient is a candidate. It depends on medical history, airway assessment, implant choice, and the surgical plan. But for those who qualify, the difference in the first 24 to 48 hours after surgery is real — and it’s one of the reasons some patients now come in specifically asking whether Preserve and sedation are options for them.

The important thing to understand is that neither is a shortcut. The surgery itself takes the same amount of time and requires the same care. What changes is the physiological cost of getting through it.

Implant longevity and the revision conversation

Modern breast implants are durable, but they aren’t permanent. The FDA no longer requires a specific replacement interval, and implants don’t have a shelf life the way milk does. But the honest expectation is this: most patients who have an augmentation in their twenties or thirties should plan for the possibility of at least one revision or exchange over their lifetime.

That revision might be for a specific reason — a rupture that requires replacement, capsular contracture (scar tissue that tightens around the implant and firms up the breast), or a shape change that no longer fits the patient’s goals. It might also be elective — a size change after childbirth or weight loss, a switch from saline to silicone, or a lift added to address natural sagging that occurs with age regardless of whether implants are present.

A surgeon who tells you implants are “lifetime devices” is misinforming you. That framing was more common in the marketing of the 1990s and 2000s and has largely fallen out of favor for a reason: it doesn’t match what patients actually experience. Being upfront about the likelihood of eventual maintenance isn’t discouraging — it’s the honest baseline for making a good long-term decision.

Ask your surgeon what their revision rate is, how they handle exchange surgery, and what the estimated cost would be if a revision were needed down the line. A well-run practice will have thought about this and won’t be surprised by the question.

What “natural” really means

Almost every patient who comes in for a consultation says some version of the same thing: they want the result to look natural. The word means slightly different things to different people, but the underlying idea is consistent — they don’t want it to look done.

Natural is not, at its core, a function of which implant brand you choose or which technique gets used. It’s a function of proportion. A modest augmentation on the right frame, with the right placement, will look natural almost by default. A very large implant on a small frame will look obviously augmented no matter how sophisticated the technique, no matter how expensive the implant, no matter how skilled the surgeon.

Natural is proportion. The best techniques in the world can’t make a mismatch between implant and frame disappear.

This is where the consultation matters more than any single technical decision. A surgeon who spends time measuring your chest, discussing what implant sizes actually fit your anatomy, and gently steering you away from sizes that will look out of place is doing the most important part of the job. The technique, the placement, the incision — all of it comes after that first, harder conversation.

If you understand that going in, everything else in this article becomes easier to navigate. The technical decisions are important, but they’re in service of a bigger one: choosing a result that looks like it belongs on your body.
