Transaxillary dual-plane breast augmentation is breast augmentation in which the implant is placed through a short incision in the armpit into a dual-plane pocket, with the upper part of the implant beneath the chest muscle and the lower part beneath the breast gland.
Over twenty-five years I have used every incision and weighed every implant pocket, and when patients ask which combination I prefer, my answer is clear: the underarm route with a dual-plane pocket. It is not the easiest approach. Building that pocket through a small incision at the far side of the chest demands specialized instruments and an anatomical map that takes years to develop. But for a woman who wants a natural result with no scar on the breast, it is the combination I have made my standard.
This article covers how a dual-plane pocket is built through the armpit and why I combine the two. For candidacy, implant sizing, recovery, costs and my full case series, see my page on breast augmentation in Dubai.
What are the key takeaways about transaxillary dual-plane breast augmentation?
The combination gives an unmarked breast and the soft upper slope of a dual-plane pocket, but the lower muscle release, the step that shapes the result most, has to be judged from the far side of the chest.
- The dual-plane pocket places the implant beneath the muscle at the top and beneath the gland at the bottom.
- Built through the armpit, the pocket is entered at the outer border of the pectoral muscle, the natural doorway into the plane beneath it.
- The lower muscle release, the step that shapes the result most, is made from the far side of the chest and graded to each breast.
- Instruments I designed, a protected sleeve and long-reach dissectors, keep the incision to 2.5 to 4 cm and the implant untouched by skin on its way in.
- Muscle cover is linked to lower capsular contracture, but some movement with muscle contraction is common whenever the muscle is involved, which is why the release is graded.
- Because the muscle is released, strenuous upper-body activity waits four to six weeks.
Why do I combine the armpit route with a dual-plane pocket?
I combine them because each gives what the other cannot: the armpit route leaves the breast unmarked and the gland untouched, and the dual plane gives the muscle cover above and the natural lower breast below that make the result look like the patient’s own.
I began with the incision beneath the breast, because it is the easiest way to see the pocket being built. I moved to the underarm when I realized that what my patients cared about most, an unmarked breast, an intact gland and a nipple that still feels, were exactly the things the breast incisions could not promise. More than 950 transaxillary augmentations later, it is my standard for well-shaped breasts that need volume, and the dual plane is the pocket I use in every augmentation I perform.
The two also fit together anatomically: the tunnel from the armpit arrives at the outer border of the pectoralis major, which is exactly where the plane beneath the muscle begins. How the armpit route itself is performed, and where its limits lie, is the subject of my article on the hidden underarm incision; how the dual plane works in general, and what each level of release does to the shape, is set out in my article on the dual plane. When a breast also needs a lift, a constricted lower breast must be released, or a major revision needs direct vision, I use the fold instead, and I say so at consultation.
How is a dual-plane pocket built through the armpit?
The dual-plane pocket is built from the outer border of the pectoral muscle: the plane beneath the muscle is opened, extended up and inward, and then the muscle’s lower attachments are divided along the fold so the gland covers the lower part of the implant. Every boundary is set from the far end of a narrow corridor.
| Step | What is done | What makes it harder from the armpit | How I manage it |
|---|---|---|---|
| Entry beneath the muscle | The plane beneath the pectoralis major is entered at its outer border | The entry point is at the end of a tunnel rather than under the incision | The muscle edge is identified by touch before the plane is opened |
| Upper and inner pocket | The pocket is extended up and toward the breastbone beneath the muscle | The inner boundary is far from the incision | The muscle’s attachments to the breastbone are preserved, so the implants cannot drift toward each other |
| Lower muscle release | The muscle’s lower attachments are divided along the fold so the gland covers the lower implant | This is the step furthest from the incision, and it is done without direct view | The fold is marked standing beforehand, the release is taken to that mark, and both sides are compared as I go |
| Outer boundary | The outer edge of the pocket is set | Over-dissection toward the armpit is easy from this route | The outer boundary is kept conservative, because an implant that drifts outward is hard to bring back |
| Pocket preparation | Bleeding is controlled and the pocket irrigated | The far corners of the pocket are a long reach away | Dissectors I designed for the route reach the whole pocket from the armpit |
| Implant insertion | The implant passes into the pocket | The implant must pass skin and axillary tissue on its way | A protected sleeve carries it in without contact |
| Final check | Position, symmetry and drape are confirmed | The pocket was never seen directly | The patient is brought to a seated position on the operating table before closure |
How to read this table: Read each row from left to right: the step, what it involves, why the armpit makes it harder, and what I do about it. The third row is the one that most changes the result, and the reason this combination takes longer to master than the same pocket built from the fold.
How is the lower muscle release judged without seeing it directly?
The lower release is judged by touch, against a fold marked with the patient standing before surgery, and by comparing the two sides continuously; it is then confirmed with the patient sitting up before closure. Some surgeons use an endoscope for this step; I work by touch.
A chest is never symmetric, so the second side is built to match the first rather than to a template. The seated check is what closes the loop: if one implant sits higher, the release on that side is adjusted before the incision is closed.
How much of the muscle is released?
The muscle is released only as far as the breast requires: less where the gland is firm and well attached to the muscle, more where the lower breast is loose or the gland has slid down. The decision is made during surgery, not beforehand.
Releasing too little leaves the implant riding high under a tight lower breast; releasing too much lets the muscle retract upward and gives up some of the cover the dual plane exists to provide. The spectrum of release and what each level does to the shape are set out in my article on the dual plane, and how the plane compares with the others in how implant pocket selection shapes the final look.

What instruments make the shorter incision and the no-touch insertion possible?
The instruments I designed for this route, a protected insertion sleeve and dissectors shaped for the long reach to the lower breast, let me hold the incision to 2.5 to 4 cm instead of the standard 4 to 5 cm and pass the implant without it touching skin or glove.
A cohesive gel implant does not compress well, which is why the textbook incision is longer. The sleeve carries it past the skin and the axillary tissue in one smooth passage, and the dissectors let me build the far corners of the pocket with the same control I would have from the fold. The no-touch passage matters as much as the length of the scar, because contamination of the implant on the way in is thought to contribute to capsular contracture. A 2022 systematic review of funnel-type insertion devices found lower capsular contracture rates and shorter incisions with no-touch insertion, though five of its six studies were retrospective and most compared a surgeon’s later cases with earlier ones, so the size of the benefit is not settled. My sleeve is my own design rather than the commercial funnel those studies used, but it works on the same principle.
What mistakes in building a dual plane from the armpit do I avoid?
The mistakes that matter most are releasing the muscle too little or too much, releasing its attachments to the breastbone, over-dissecting toward the armpit, and handling the implant through the skin. Each has a specific step designed to prevent it.
| Mistake | What it causes | How I avoid it |
|---|---|---|
| Incomplete lower release | The implant rides high under a tight lower breast | The release is taken to the fold marked standing and checked with the patient sitting up |
| Excessive release | The muscle retracts upward, its edge can show through thin skin, and upper cover is lost | The release is graded to the breast rather than taken to a fixed level |
| Releasing the attachments to the breastbone | The implants drift toward each other and the cleavage merges | These attachments are preserved; the inner pocket is extended beneath them, not through them |
| Over-dissecting toward the armpit | The implant drifts outward when lying down | The outer boundary is kept conservative |
| Building each side in isolation | Visible asymmetry | The two sides are compared at every stage and checked seated |
| Handling the implant through the skin | Contamination thought to contribute to capsular contracture | A protected sleeve carries the implant in without contact |
How to read this table: Each row pairs an error with its visible consequence and the step that prevents it. Most of them arise from the distance between the incision and the pocket, which is why the prevention is built into the sequence rather than left to correction afterward.
Why the boundaries of the pocket, more than the implant itself, decide whether the result stays where it was placed is set out in my article on implant pocket control and long-term stability.
What does the evidence show about the muscle when the dual plane is built from the armpit?
The evidence shows that covering the implant with muscle lowers the risk of capsular contracture, but also that some movement of the breast when the muscle contracts is common whenever the muscle is involved. Only one of these studies looked at the armpit route specifically, and it points the same way: the less muscle the result needs, the less there is to move.
A 2025 systematic review and meta-analysis found about a third the odds of capsular contracture with placement beneath the muscle compared with placement above it, which is the main long-term argument for keeping the muscle over the upper implant.
The muscle has a cost, and it is worth stating plainly. A 2019 systematic review of animation deformity found some degree of breast movement with muscle contraction in a median of 58% of patients across the four studies that measured it properly, with the highest figures after dual-plane and similar techniques; the authors state that its true incidence and cause have yet to be established. A 2024 comparison of 82 transaxillary patients found less pain and no animation when most of the pocket was moved above the muscle, against two cases in forty with the conventional dual plane. That is why I grade the release to each breast rather than taking it to a fixed level, and why in my practice most women describe the movement, where it occurs at all, as slight.
| Source | Design | What it found | What it does not show |
|---|---|---|---|
| Haas and colleagues, 2025 | Systematic review and meta-analysis; 11 studies with 17,707 cases compared placement planes | About a third the odds of capsular contracture beneath the muscle than above it (odds ratio 0.35) | Results for the dual plane or the armpit route specifically; half the included studies date from the 1980s and 1990s |
| Ya, Xiao and Zhou, 2024 | Comparison of 82 endoscopic transaxillary augmentations: 40 dual plane, 42 reverse dual plane | Less pain and no animation in the mainly subfascial reverse dual plane, against 2 of 40 with the dual plane | A settled advantage: single center, patient-assessed outcomes, and an animation difference resting on two events |
| Dyrberg and colleagues, 2019 | Systematic review of studies that defined and graded animation deformity; four studies included | Some degree of animation in a median of 58% of patients, highest after dual-plane and similar techniques (73 to 78%) | Its cause or true incidence, which the authors state have yet to be established |
How to read this table: The third column is what each source supports and the fourth is where it stops. Together they describe a trade-off rather than a verdict: muscle cover protects against contracture, at the cost of some movement that the release is graded to limit.
What does recovery after the dual-plane release involve?
Because the muscle is released, the upper breast feels tight for the first days and strenuous upper-body activity, including chest training, waits four to six weeks so the pocket can stabilize. Most patients are back at desk work within four to five days.
The full recovery timeline, from the first days to swimming and exercise, is set out on my page on breast augmentation in Dubai. Where significant sagging accompanies volume loss, augmentation is sometimes combined with a breast lift in Dubai, which changes both the route and the recovery.
Why does respecting the muscle matter as much as hiding the scar?
Respecting the muscle matters because the scar decides whether the operation shows, but the muscle decides how the breast moves and ages. Releasing it only where needed is what keeps a hidden-scar result looking natural over time.
Respect the anatomy, and it rewards you: the breast left unmarked, the gland left whole, the muscle released precisely where needed and no further, and the implant placed in a pocket shaped for it. This principle runs through my work in aesthetic plastic surgery in Dubai, and every plan is individualized and discussed candidly at consultation.
What do patients ask most about transaxillary dual-plane breast augmentation?
Patients most often ask whether the implants will move with the muscle, whether the armpit route changes the release, and whether the pocket can be built as precisely from the armpit; the answers below are specific to this combination.
-
Will my implants move when I use my chest muscles?
Some movement when the chest muscle contracts is common whenever the implant lies partly beneath the muscle, and published reviews record it in many patients after dual-plane augmentation. I grade the release to each breast to limit it, and in my practice most women describe it, where it occurs at all, as slight.
-
Does the armpit route change how much of the muscle is released?
No. How much of the muscle is released is decided by the breast, not by the route: less where the gland is firm and well attached, more where the lower breast is loose. What the armpit route changes is how the release is judged, by touch against a fold marked standing and confirmed with the patient sitting up, rather than under direct view.
-
Can a dual plane be built as precisely through the armpit as through the fold?
Yes, with the right instruments and method, although it is harder. The fold gives a direct view of the lower release; from the armpit it is judged by touch against a fold marked standing, with the two sides compared throughout and the result confirmed with the patient sitting up before closure.
-
What is a no-touch insertion sleeve?
It is a protected sleeve that carries the implant through the armpit incision into the pocket without it touching skin, axillary tissue or gloves. It allows a shorter incision of 2.5 to 4 cm and removes a source of contamination thought to contribute to capsular contracture.
-
When can I return to chest exercise after a transaxillary dual-plane augmentation?
Strenuous upper-body activity, including chest training, waits four to six weeks so the released muscle and the pocket can stabilize. Light activity and desk work resume much sooner, usually within four to five days.
-
Can the dual plane be adjusted later through the same armpit incision?
Minor adjustments, such as an implant exchange or a small pocket correction, can usually be made through the same incision. A major revision that needs direct vision, such as removing a contracted capsule or rebuilding the pocket, is done through the fold beneath the breast.
