Transaxillary Breast Augmentation: The Scarless Korean Approach

What Is Transaxillary Breast Augmentation?

Transaxillary breast augmentation is a breast enlargement technique in which the surgeon places the breast implant through a small incision hidden in the armpit (axilla) rather than on the breast itself. Because the entry point sits in a natural fold of the underarm, the breast skin is left untouched, and the visible reminder of surgery is kept well away from the chest.

The word “transaxillary” simply means “through the armpit.” In practice, the surgeon makes a short incision in the underarm, then guides the implant upward into a pocket created behind the breast tissue or the chest muscle. The implant travels from the armpit to its final position, so the breast surface never carries a cut.

For many patients, that single detail is the whole appeal. A scar on the breast, even a faint one, can be a constant reminder of surgery and a worry in swimwear or intimate settings. Moving the entry point to the armpit addresses that concern directly, which is why scar-conscious patients often ask about this route by name. The technique is widely associated with Korean cosmetic surgery, where endoscopic methods have been refined over many years.

Why “Transaxillary” Means Through the Armpit

The axilla is the medical term for the armpit. A transaxillary approach uses this area as the doorway to the breast, taking advantage of the loose, naturally creased skin there. The incision is typically about 3 to 4 cm long and sits within a natural armpit fold. Placing the entry point in this discreet location is the defining feature that separates the transaxillary route from incisions made on or near the breast.

How It Differs From Conventional Breast Augmentation

In many conventional procedures, the incision is made directly on the breast, either in the crease beneath it or around the lower edge of the areola. The transaxillary method moves that incision off the breast entirely. This is a technique MINE Plastic Surgery has refined over years of endoscopic practice, pairing the armpit approach with camera-assisted precision. For readers weighing every option, our complete guide to breast augmentation methods compares implants and fat transfer in more depth.

How the Endoscopic (Scarless) Technique Works

The transaxillary approach is often marketed as “scarless” because no scar is left on the breast itself, although a small, well-hidden scar still forms in the armpit. What makes the modern version reliable is the endoscope: a slim camera that lets the surgeon see deep inside the body while working far from the small armpit incision. The endoscope magnifies the surgical field, allowing the implant pocket to be shaped under direct view through a single armpit incision.

Endoscopic Visualization & the Dual-Plane Pocket

Working far from the incision once meant operating partly by feel. Endoscopic visualization changes that, projecting a magnified, lit view of the tissue onto a monitor so the surgeon can dissect precisely. MINE performs this as part of its HD endoscopic breast augmentation protocol.

Many cases use a dual-plane technique, in which the implant sits partly under the pectoralis (chest) muscle and partly under the breast gland. In plain terms, the upper portion of the implant is cushioned by muscle for a softer, more natural slope, while the lower portion follows the gland to fill the breast shape. The endoscope makes it easier to release and position these layers accurately.

This layered placement is one reason endoscopic visualization is so useful. Releasing the muscle correctly and shaping the pocket symmetrically are detailed steps, and doing them through a distant armpit incision is far more controlled when the surgeon can watch each move on a high-definition monitor rather than relying on touch alone.

The “Dry Pocket”, Fascia & Nerve Preservation

A “dry pocket” refers to meticulous cauterization of small blood vessels as the pocket is created, which aims to reduce bleeding during and after surgery. By keeping the pocket as bloodless as possible, the technique aims to lower the risk of hematoma (a collection of blood), though no method can eliminate that risk entirely.

During dissection, the surgeon also works to preserve the fascia (the connective tissue layer) and the sensory nerves around the pocket. Protecting these nerves is linked to maintaining nipple sensation after surgery, which is a meaningful concern for many patients. Because the endoscope shows these delicate structures clearly on screen, the surgeon can work around them with greater care than a blind approach would allow.

None of this removes risk altogether, and the language here matters: a careful technique aims to lower the chance of bleeding or sensory change, but it cannot promise to prevent them. Honest expectations are part of good surgical care, and the risks section below sets them out in full.

3D Scanning for Pre-Surgical Planning

Before the operation, a 3D breast scanner can be used to measure the chest, model breast shape, and plan implant sizing and symmetry. This pre-surgical mapping helps the surgical team and the patient align on a realistic, proportionate outcome before the procedure begins, rather than deciding sizing on the day of surgery.

Transaxillary vs Inframammary vs Peri-areolar Incisions

There is no single “right” incision for every patient. The three most common routes place the scar in different locations, and each carries its own trade-offs. The table below summarizes how they compare so you can see the differences at a glance.

Comparison Table: Incision Site, Visible Scar & Suitable Candidates

Incision approach	Where the scar is	Scar visibility on breast	Typical considerations
Transaxillary (armpit)	In a natural fold of the armpit	None on the breast	Suited to patients who want no scar on the breast; endoscopy helps with precise pocket creation.
Inframammary (breast crease)	In the fold under the breast	Hidden in the under-breast crease	Widely used; gives the surgeon direct access to the pocket.
Peri-areolar (nipple edge)	Along the lower border of the areola	At the areola edge, can blend with the color change	May carry a potential impact on nipple sensation and breastfeeding; discussed case by case.

Trade-offs of Each Approach

Each approach has trade-offs. The transaxillary route keeps the breast free of any scar but reaches the pocket from a distance, which is why endoscopic visualization matters. The inframammary route offers direct access but places a scar on the breast crease. The peri-areolar route hides the scar at the areola border but sits closer to milk ducts and nerves.

It also helps to think beyond the scar itself. Surgeons weigh how easily each route allows accurate pocket creation, how it may affect future imaging or revision, and how it suits a patient’s body type. No single approach wins on every measure, which is exactly why the decision is made together rather than chosen from a list online.

The right choice depends on your anatomy, your priorities, and the goals you discuss in consultation. If you are also comparing implant-based options with natural-tissue methods, our overview of fat transfer vs implants can help frame that decision.

Scarring After Transaxillary Breast Augmentation: Why the Armpit Incision Stays Hidden

Let us be clear: there is a scar. The transaxillary technique does not erase scarring; it relocates it. The scar forms in a natural crease of the armpit rather than on the breast, and the breast surface carries no incision because the implant is introduced via the armpit. Over the following months its appearance usually fades, but like any surgical scar it never disappears entirely.

Where the Scar Actually Forms

The incision is placed within an existing armpit fold so that, as the area heals, the line tends to settle into the crease and become less noticeable. Surgeons often close the deeper layers with dissolvable sutures, which support the wound from the inside and help keep the visible armpit scar fine.

Scar Care & Realistic Expectations

Good scar care is straightforward but important: keep the area clean, avoid sun exposure and tension on the healing skin, and follow your surgeon’s specific guidance on movement and dressings. How a scar matures varies from person to person, depending on skin type and individual healing, so two patients can have different results from the same technique.

It is worth repeating that “scarless” is a nickname for this method, not a literal promise. It describes the absence of a scar on the breast, not the absence of any scar at all.

Recovery Timeline After Transaxillary Breast Augmentation

Recovery after transaxillary breast augmentation follows a general arc, though the exact pace differs for each patient. Most patients return to light daily activities within about one week, while strenuous exercise is usually avoided for 4 to 6 weeks. The timeline below offers a typical guide, not a guarantee, and your surgeon’s clearance always takes priority. Factors such as age, activity level, and how your body heals can shift these windows in either direction.

First Week: Swelling & Arm Movement

In the first few days, some soreness in the arm and shoulder is expected, precisely because the implant traveled through the armpit. Overhead arm motion is usually limited at first, and swelling around the chest and underarm is normal. Many patients resume light desk work after about a week, though this varies.

Weeks 2–6: Returning to Routine

Over the next several weeks, most people gradually return to everyday activities. Heavy lifting and dedicated chest or arm exercise are typically held off until your surgeon clears you, since the implant pocket and the armpit tissues are still settling during this window.

Months 1–3+: Settling & Final Shape

Swelling continues to subside over the following months, and the implants gradually settle into a more natural position, a process patients often hear described as “drop and fluff.” The final shape generally emerges over several months. For a deeper look at the whole healing arc, see our breast augmentation recovery guide.

Who Is It For? Candidacy and Risks

The transaxillary approach tends to suit patients who specifically want no scar on the breast, have suitable chest and armpit anatomy, hold realistic expectations, and are in good general health and non-smoking. Final suitability, however, is always decided during an in-person consultation, where your surgeon can assess your tissue and goals directly.

Good Candidates for the Transaxillary Approach

Scar-conscious patients are often drawn to this method because nothing on the breast itself signals that surgery took place. That said, candidacy is not one-size-fits-all: skin elasticity, chest width, existing breast tissue, and the implant plan all factor in. International guidance from bodies such as ISAPS underscores that surgical planning should be individualized and led by a qualified, board-certified surgeon.

Lifestyle matters as well. Smoking can impair healing, and a history of certain breast conditions may shape which incision and implant plan are appropriate. A thorough consultation, ideally with imaging, gives the surgeon the information needed to recommend, or advise against, the transaxillary route for your individual case.

Risks & Possible Complications (Must Read)

As with any breast implant surgery, transaxillary breast augmentation carries real risks that every patient should understand before deciding. Possible complications include:

• Bleeding or hematoma (a collection of blood in the pocket)
• Infection
• Capsular contracture (hardening of scar tissue around the implant)
• Implant malposition or rotation (the implant shifting from its intended position)
• Changes in nipple or skin sensation
• The possibility of revision surgery

It is also important to know that breast implants are not lifetime devices and may need to be replaced or removed over time. In addition, because the transaxillary route reaches the pocket from the armpit, some future revisions can be more complex than with an incision on the breast itself. The FDA breast implants information page is a useful authority on device safety, including capsular contracture and the fact that implants may not last a lifetime. For a focused read on complications, see our article on breast augmentation side effects.

Cost is not listed here because it depends on individual factors such as implant type and the specifics of your surgical plan. The most accurate way to understand pricing and suitability is a personalized consultation rather than a fixed online figure.
