Most conversations about breast augmentation begin with size. How big, how round, how natural. That is a reasonable place to start, and the size conversation gets plenty of attention elsewhere. But two decisions that happen earlier in the planning, and that are rarely discussed in glossy brochures, quietly determine more of the long-term experience than the cup size ever will. One is the incision: the place where the surgeon enters. The other is the pocket: the place where the implant ends up living.
Together, those two choices decide where the visible scar sits, how the nipples feel afterward, how sore the first week is, how the breast moves when the chest muscle flexes, how the implant looks at six months and at sixteen years, how easily a future surgeon can operate again, and how mammograms are read. Patients who understand them walk into the consultation able to ask better questions, and surgeons who explain them well tend to have patients who are less surprised later.
This guide describes each incision and each pocket, who tends to fit which, what trade-offs come with them, and how they interact with implant type, anatomy, lifestyle and future plans. It is general education written from the perspective of Ayala Plastic Surgery in San Antonio, and the right combination for any individual is decided at an in-person examination with Dr. John Ayala.
Two decisions that are made before the implant is chosen
It helps to separate the vocabulary. The incision is the cut in the skin through which everything happens. The pocket, sometimes called the plane, is the space the surgeon creates to hold the implant, and it can be above, partly below or entirely below the pectoralis major, the broad chest muscle. The two decisions are related but not identical: a surgeon can reach any of the pockets through more than one incision, although some combinations are more natural than others.
Neither decision is purely cosmetic. The incision affects how much sensation is at risk and what is physically possible during the operation. The pocket affects how the implant is covered by the patient's own tissue, which influences visibility, rippling, movement and the way the breast ages.
Implant choice, meaning the size and profile a patient settles on, interacts with both. A larger or firmer silicone implant needs a longer incision than a small saline one that is inserted empty and filled, and a thin patient with little natural breast tissue has different coverage needs from someone with ample tissue. These variables are weighed together and not one at a time.
The four doors into the breast
Surgeons describe four possible approaches, though in modern practice two of them account for the great majority of cases.
The fold: the inframammary incision
The inframammary incision sits in the crease beneath the breast, the fold where the breast meets the chest wall. It is the most widely used approach for good reasons. It gives the surgeon a direct view of the pocket, which allows precise control of its size and position. It works with every implant type and size, including large silicone gel implants that need a longer opening. It does not pass through breast tissue or the milk ducts. And if a future revision is needed, the same scar can be reopened.
The scar is typically a line of a few centimeters, usually between about four and six centimeters depending on the implant. In most patients it settles into the crease and becomes hard to see when standing, although it can be visible when lying down or lifting the arms, and it is sometimes more noticeable on a very small, high-set breast where the fold is shallow. Where the fold sits matters. If the new implant is larger than the old breast, the fold may need to be lowered or repositioned, and a skilled surgeon plans the incision accordingly so that the scar ends up in the final crease and not above or below it.
Downsides are modest. Patients with a tendency toward thick or raised scars will see that in the fold as elsewhere. Some patients simply dislike the idea of any scar on the breast mound, and that preference is a legitimate reason to consider another route.
The edge of the areola: the periareolar incision
The periareolar approach places the cut along the lower border of the areola, where the pigmented skin meets the lighter skin. Its great appeal is camouflage, because the color change disguises the scar, which often fades to a fine pale line.
It also has real limits. The areola must be large enough to accommodate the implant, so this approach suits smaller to moderate implants and is a poor match for larger silicone gel devices unless the areola is generous. It requires passing through breast tissue, which brings concerns about changes in nipple sensation and about the ability to breastfeed, since some milk ducts lie in the path. The evidence on whether it raises the chance of capsular contracture is debated, with some studies suggesting a modest increase and others finding little difference, but many surgeons take the question seriously enough to discuss it. The scar can also widen or lighten in ways that make it more visible, particularly on the areola's edge in patients with darker or lighter skin.
Patients who are considering a later areola reduction or who are planning a lift at the same time often see the periareolar route become part of a larger incision strategy, since the areola is already being worked on.
The armpit: the transaxillary incision
The transaxillary approach goes through a small incision in the armpit, tunneling to the breast pocket, often with the help of an endoscope, a small camera. Its attraction is that it leaves no scar on the breast itself, which appeals to patients who want the breast to look untouched.
The trade-offs are significant. Working through a tunnel from the armpit gives the surgeon less direct control over the shape and position of the pocket, particularly the lower portion, so precision is harder. It is difficult to combine with certain techniques, such as adjusting the fold, and it is not well suited to correcting asymmetry or to revision, which often requires a second incision on the breast anyway. Because the scar sits in a skin crease it is usually hidden when the arm is down, but it can be visible in sleeveless clothing or when the arm is raised. Surgeons who do this operation often need specific experience and equipment.
The navel: the transumbilical route
The fourth approach enters through the belly button, tunneling up to the breasts, and it is suitable only for saline implants that are filled after placement. It is uncommon because of limited control, difficulty positioning the implant precisely, and incompatibility with silicone gel. It appears in textbooks more than in most San Antonio consultation rooms, and few surgeons recommend it today.
Choosing among them: a short logic
Rather than ranking incisions as better or worse, surgeons match them to the patient. A few patterns recur.
A patient who wants a larger silicone gel implant almost always ends up with an inframammary incision, because the opening has to be long enough to place a prefilled device without damaging it. A patient with a smaller implant and a relatively large areola might be a candidate for periareolar. A patient who strongly prioritizes no breast scar and has an appropriate anatomy and implant may be offered transaxillary, with an honest discussion about the limits.
Anatomy shapes the choice too. A low or shallow fold is easier to work with from below. A tuberous or constricted breast, where the base is narrow and the tissue is tight, often requires a more extensive approach that releases the lower pole, which can be done through the fold or the areola but is more complex than a standard operation, which is the territory of tuberous breast correction. Significant sagging calls for a different conversation entirely, since an incision pattern that includes a lift may be necessary, which is how a lift with augmentation gets planned.
Future plans matter. A woman who expects to breastfeed in the coming years may prefer an approach that avoids the breast tissue. A woman with a history of thick scarring may weigh the location of the scar more heavily. And someone who anticipates that the implants will eventually be replaced should think about whether the chosen route will allow easy access later.
The pocket: three places an implant can live
With the door chosen, the second decision is where the implant sits relative to the muscle and the breast tissue. The options are best understood as layers.
Above the muscle: subglandular
In the subglandular position, the implant lies behind the breast tissue and in front of the pectoralis major. The operation is shorter and recovery is typically more comfortable, since the muscle is not disturbed. Because the implant sits closer to the front of the chest, it can give a fuller appearance in the upper pole and tends to follow the shape of the breast tissue directly. The implant does not move when the chest muscle flexes, which matters to athletes and to patients who dislike the idea of motion.
The cost of this position is coverage. The only tissue between the implant and the skin is the breast tissue and the skin itself. In a patient with a thick layer of natural tissue this is fine, but in a thin patient the edges of the implant can be visible or palpable, and rippling, the faint waves that can show on the surface of a saline or even a silicone implant, is more likely. Many studies find a higher rate of capsular contracture in this position, although the data are mixed and technique matters.
Partly under the muscle: dual plane
The dual plane approach is the most common modern pocket. The upper part of the implant sits beneath the pectoralis major, which is released along its lower attachment, and the lower part sits beneath the breast tissue. It combines advantages of the other two positions: muscle coverage at the top, where the implant edge would otherwise show and where natural tissue is thinnest, and direct contact with the breast tissue below, which allows the implant to fill the lower pole and helps shape a natural slope.
The dual plane works well across a wide range of body types and is particularly helpful for patients with mild to moderate sagging, since it allows the breast tissue to redrape over the implant. Recovery is somewhat sorer than for subglandular placement because the muscle has been lifted, and some patients feel tightness across the chest for a few weeks.
Fully under the muscle: submuscular
True submuscular placement puts the entire implant under the pectoralis, usually with additional release of the muscle's origin along the sternum. It provides the greatest coverage and is sometimes chosen for very thin patients or when maximum camouflage of the implant edge is the priority. It also tends to produce a subtler upper pole.
The compromises are more pain, a longer recovery, and a higher chance that the implant sits higher on the chest early on. When the muscle contracts, it can push the implant upward or sideways in a movement known as animation deformity, which is more noticeable in patients who exercise heavily or who use their chest muscles intensively. For these reasons, the full submuscular position is less often the first choice than it once was.
A fourth option: under the fascia
Some surgeons use a subfascial pocket, placing the implant above the muscle but beneath the thin layer of tissue that covers it, called the pectoral fascia. This adds a little extra coverage over a subglandular pocket without disturbing the muscle. The benefit is a modest one, and surgeons differ in how much they value it.
How tissue thickness decides the pocket
Surgeons often use a simple measure: how thick is the soft tissue at the upper part of the breast? A common rule of thumb is the pinch test, assessing the thickness of tissue over the upper chest. A thin layer suggests that under-the-muscle coverage will help hide the implant. A thick layer suggests that above-the-muscle placement may look natural without it.
This is a guide and not a rule. Implant size, shape and type also matter. A small silicone gel implant behind thick tissue may look natural in nearly any position, while a large saline implant in a thin patient is a recipe for visible rippling regardless of the plane. The honest approach is to treat the pocket as a function of anatomy, implant and lifestyle, and to explain the reasoning to the patient in plain terms.
Lifestyle, and the muscle that flexes
Patients who train their chests, such as weightlifters, climbers, swimmers and some yoga practitioners, often ask which pocket works best. The most important point is that muscle coverage means muscle movement. A dual plane or submuscular implant may shift slightly when the chest contracts, which can be mildly visible and sometimes uncomfortable in heavy lifting. For this reason, active patients are sometimes steered toward above-the-muscle or subfascial placement, if their tissue allows, and sometimes toward a dual plane with a carefully limited release of the muscle. The right answer is a balance between camouflage and motion, and it is one more reason to describe training habits at the consultation.
Recovery looks different depending on the choice
The pocket changes the first weeks more than the incision does.
For an above-the-muscle placement, patients commonly describe soreness and tightness that eases within several days, with many returning to desk work within about a week. For a dual plane or full submuscular placement, soreness is more pronounced, particularly in the first several days, and can feel like a deep ache or like the chest is being squeezed. Prescribed pain medication and a surgical bra help, and activity limits on lifting and arm movement last longer.
Implants placed under the muscle sit higher at first and often appear tight and somewhat unnatural for the first weeks, a phase usually described as the implants dropping and fluffing as the muscle relaxes and the tissue settles. Patients sometimes worry in this period, and the expected timeline of swelling, settling and softening is worth knowing in advance. Swelling, settling and softening follow the same broad recovery timeline as other plastic surgery, with the implant specifics layered on top.
Scars follow their own schedule. Early on they are pink and raised, and they typically mature and fade over a year or more. Silicone sheeting or gel, sun protection and avoiding tension on the incision are standard advice, and patients with a history of keloids or thick scarring should say so in advance.
What each choice means for long-term issues
Several long-term considerations are shaped by the incision and the pocket, and they are worth understanding before surgery.
Capsular contracture
The body forms a thin capsule of scar tissue around any implant, and in a minority of patients that capsule tightens and hardens, causing firmness, distortion and sometimes pain. The causes are not fully understood. Factors that surgeons consider include the pocket (above the muscle is associated with higher rates in several series), avoiding contamination during surgery, using no-touch techniques, and the choice of incision. When it occurs, it often calls for implant revision surgery.
Mammograms and imaging
Implants make mammography more complex, and placement matters. Implants under the muscle may allow somewhat better visualization of breast tissue than implants above it, although techniques exist to image either. Patients should tell the imaging facility about their implants. Silicone gel implants also come with recommendations from regulators for periodic imaging to check the implant's integrity, and the schedule is something to discuss with the surgeon.
Future surgery
Most implants are not lifetime devices, and many patients eventually have them replaced or removed. The original incision and pocket influence how straightforward that is. A fold incision can be reused. A transaxillary or periareolar scar may not give adequate access, and the pocket may need to be changed, for example from above to below the muscle to address contracture or visibility. Patients who think they may want removal one day should consider how explant surgery would be done through the original incision.
Aging
Breasts change with age, weight and pregnancy, and an implant does not stop that. Implants above the muscle are more likely to show the effects of gravity as the tissue stretches, whereas those under the muscle are supported at the top. Either can sag, rotate or sit differently over time, and many patients eventually consider a lift to refresh the shape.
Sensation and breastfeeding
Two questions arise in nearly every consultation.
Nipple sensation can change after any breast augmentation. The nerves that supply the nipple travel through the tissue, and stretching or cutting them, especially at the periareolar approach or with large implants, can lead to temporary or lasting numbness or, less often, hypersensitivity. Most patients recover most of their sensation within months, but some do not.
Breastfeeding is possible for many women after augmentation, but not guaranteed. The incision through the areola and breast tissue carries a higher risk of affecting milk ducts and nerves, while the fold and armpit routes avoid them. Women who are planning pregnancy should discuss this explicitly. The pocket matters less for breastfeeding than the incision does, although both are part of the conversation.
Choosing silicone or saline changes the incision
Implant type feeds back into the incision. Saline implants arrive empty and are filled once in place, so they can be inserted through a smaller opening, which makes the periareolar and transaxillary routes more practical. Silicone gel implants arrive prefilled and are firmer, so they need a longer opening to avoid stressing the shell, which favors the fold. Newer cohesive gel implants hold their shape, and they are usually placed through the fold as well.
The general pattern is that the smaller the incision a patient wants, the narrower the implant choices become. Patients should hear that trade-off before falling in love with a specific plan.
When augmentation is combined with other procedures
Breast augmentation is often part of a larger plan, and the incisions must fit together. In a mommy makeover, for instance, the breast work is combined with a tummy tuck and sometimes liposuction, and surgeons plan the order, the positioning and the recovery around all of it. In those cases the incision decision may be influenced by the time under anesthesia and by how many areas are being treated at once. Patients with significant sagging may need a lift pattern that changes the entire incision strategy.
Cost and what drives it
The price of augmentation is built from the surgeon's fee, the facility, anesthesia, the implants and follow-up care. The incision and pocket can affect the cost indirectly, because a longer or more complex operation, such as a revision of the pocket or a procedure combined with a lift, takes more time. Because the fee, the facility and the implants all move the total, any comparison of breast augmentation cost between practices should check what is included, not just the headline number.
Reading a plan that makes sense
A good plan for incision and pocket sounds like a sentence with reasons attached. It names the approach and the pocket and explains why they fit this chest: because the tissue is thin, because the fold is well defined, because the patient trains, because the implant needs a certain opening, because a pregnancy is planned. A plan that gives only a technique with no reasons deserves another question. Patients should also feel free to ask what the alternative would have cost them in recovery, scarring or risk, since a surgeon who has weighed the options can usually say.
It is also reasonable to ask to see photographs of scars and results at one year and later, not just a few weeks, because the incision and pocket reveal themselves over time. Early photographs show swelling more than anything else.
The decisions beneath the decision
Breast augmentation looks like a question of size and shape, but its character is set by two quieter choices. The incision decides where the scar lives and what the nerves and ducts go through. The pocket decides how the implant is covered, how it moves, how it ages and how hard it will be to change. Fold or areola or armpit, over or under or between: each has a type of patient it suits and a type it does not. A patient who understands this arrives at the consultation with a better question than how big, which is what the right shape for this particular body will cost her in scars, sensation and the years ahead.
Breast augmentation incision and pocket questions, answered
Which incision is best for breast augmentation?
There is no single best incision. The inframammary (fold) incision is the most widely used because it gives the surgeon excellent control and works with all implant types. Periareolar and armpit approaches suit selected patients who prioritize scar placement and have the right anatomy.
Where will my breast augmentation scar be?
Under the fold, it sits in the crease beneath the breast. Around the areola, it follows the lower edge of the pigmented skin. Through the armpit, it sits in a skin crease there and leaves no scar on the breast itself. Scars fade over a year or more.
Will a periareolar incision affect breastfeeding?
It can, because it passes through breast tissue where some milk ducts and nerves lie. Many women still breastfeed after augmentation, but women planning pregnancy should discuss the risk and consider an approach that avoids breast tissue.
Is it better to place implants over or under the muscle?
It depends on tissue thickness, implant type, sagging and lifestyle. Under or partly under the muscle gives better coverage in thin patients and is common today as a dual plane. Over the muscle can look natural in patients with ample tissue and avoids muscle movement and extra soreness.
What is a dual plane breast augmentation?
It is a pocket in which the upper part of the implant lies beneath the chest muscle and the lower part lies beneath the breast tissue. It combines muscle coverage at the top with direct contact with breast tissue at the bottom and suits many body types.
Does under the muscle hurt more?
Usually yes. Lifting the muscle makes recovery more uncomfortable in the first days and can leave a feeling of tightness across the chest for a few weeks. Pain medication, a surgical bra and activity limits help.
Can an implant move when I flex my chest?
Implants placed under the muscle can shift slightly when the pectoral muscle contracts, known as animation. It is more noticeable in people who lift weights, which is one reason active patients may be considered for other placements.
Do the incision and pocket affect capsular contracture?
They can. Placement above the muscle is associated with higher contracture rates in several studies, and the periareolar route has been questioned, though the evidence is mixed. Surgical technique and sterile practices matter as much as the choice itself.
Does the incision affect nipple sensation?
Any breast augmentation can change nipple sensation, and the risk is higher with a periareolar incision or very large implants. Most patients recover much of their sensation within months, but some changes can be lasting.
Can I change the incision or pocket in a later surgery?
Yes, and it is often done during revision. Surgeons may reuse the fold scar, create a new pocket or move an implant from above to below the muscle to address contracture or visibility, so the original choices influence how simple a future operation is.
