Designing a smooth upper-body line from the arms to the armpits and outer breasts
For patients considering arm liposuction, fat transfer breast augmentation, or Hybrid Breast Augmentation, one area that is often very important is the accessory breast area.
The accessory breast area refers to the bulging area that can appear in front of the armpit and along the outer side of the breast.
This bulge may make the upper body look heavier when wearing fitted clothing or sleeveless tops. It can also become more noticeable when the arms are closed.
At AVAN TOKYO, we do not design arm liposuction or breast augmentation as isolated procedures.
We design the entire upper-body line, including the arms, armpits, accessory breast area, and outer breast.
Making the arms slimmer is not always enough.
Increasing breast volume is also not always enough.
A truly refined upper-body silhouette is created when the arms, armpits, accessory breast area, and outer breast connect smoothly.

Why accessory breast fullness can make the upper body look heavy
Even if the arms become slimmer or the breasts become fuller, remaining fullness around the accessory breast or armpit area can make the upper body look bulky.
Accessory breast liposuction may be suitable for patients who have concerns such as:
● Bulging in front of the armpit when wearing sleeveless clothing
● Fat being squeezed when the arms are closed
● Fat spilling over the side of the bra
● The upper body still looking heavy after arm slimming
● Unevenness from the outer breast to the armpit
● The upper body looking thick in photos or videos
● Wanting a cleaner outer breast line after breast augmentation
Accessory breast fullness affects not only the front view, but also the side view, oblique angle, and the silhouette when the arms are closed.
For this reason, at AVAN TOKYO, we carefully assess the accessory breast and armpit area when performing arm liposuction or breast augmentation.

Accessory breast liposuction is not simply about removing a small bulge
Accessory breast liposuction is often thought of as a procedure to remove only the fat in front of the armpit.
However, at AVAN TOKYO, we consider accessory breast liposuction to be a procedure that helps create a smooth connection from the arms to the breasts.
The following continuous lines are especially important:
● Shoulder to upper arm
● Upper arm to armpit
● Armpit to accessory breast
● Accessory breast to outer breast
● Outer breast to décolletage
If a bulge or step remains in any part of this line, the overall upper-body silhouette may look incomplete.
Even if the arms become slimmer, the armpit area can still look heavy if accessory breast fullness remains.
Even if the breasts become fuller after augmentation, the outer breast line can look unclear if armpit fat or accessory breast fullness remains.
This is why accessory breast liposuction works very well with arm liposuction, fat transfer breast augmentation, and Hybrid Breast Augmentation.

Benefits of combining arm liposuction with accessory breast liposuction
In arm liposuction, it is important to design not only the arm itself, but also the shoulder, arm root, and armpit area.
Combining accessory breast liposuction may help:
● Create a smoother line from the upper arm to the armpit
● Reduce bulging when the arms are closed
● Make sleeveless and fitted clothing look better
● Make the upper body appear more delicate
● Create a more natural connection to the outer breast
If only the arms are treated and the armpit or accessory breast area remains full, the arm root may still look thick.
To create a cleaner upper-body silhouette from the front, it is important to design the arms, armpits, and accessory breast area together.

Why accessory breast liposuction works well with fat transfer or Hybrid Breast Augmentation
In fat transfer breast augmentation and Hybrid Breast Augmentation, the breast volume itself is important.
However, the surrounding contour is just as important.
If armpit fat or accessory breast fullness remains, the outer breast line may look blurred even after the breast volume increases.
By combining accessory breast liposuction, the outer breast contour can become cleaner, and the roundness of the breast may appear more refined.
In Hybrid Breast Augmentation, silicone implants create the main volume, while fat grafting improves softness and natural contour.
If accessory breast or armpit fullness remains, the breast line may still look heavy on the side.
At AVAN TOKYO, we design not only the breasts, but also the arms, accessory breast area, armpits, and décolletage as one continuous upper-body line.

It is important to treat the armpit area, not only the accessory breast
Accessory breast liposuction should not be limited only to the accessory breast bulge.
In many cases, the armpit area, outer breast, and arm root must be assessed together.
Even if the accessory breast itself is reduced, remaining armpit fat may still create thickness when the arms are closed.
For this reason, at AVAN TOKYO, we design the treatment area to include the armpit when necessary.
This allows us to aim for a smoother and more natural upper-body line from both the front and side views.

Exception: some patients may want to preserve volume in this area
For many patients, reducing accessory breast and armpit fullness can make the upper body look slimmer and more refined.
However, it is not always necessary to remove this area completely.
For example, patients who work in modeling, gravure, entertainment, or certain photo-related industries may intentionally want to keep some volume around the outer breast and armpit area.
In these cases, removing too much fullness may not match the desired image for their work.
At AVAN TOKYO, we consider each patient’s lifestyle, occupation, photography needs, and ideal appearance before deciding how much to remove.
Cosmetic surgery should not be based only on the doctor’s aesthetic preference.
The most important point is to create the best balance for each patient’s goals.

What AVAN TOKYO focuses on in accessory breast liposuction

1. Designing the arms and breasts as one connected line
   Accessory breast liposuction can be performed alone.
   However, when combined with arm liposuction or breast augmentation, it can significantly improve the overall upper-body silhouette.
   We design the upper arms, armpits, accessory breast area, and outer breasts as one connected line.
2. Checking the appearance when the arms are closed
   Accessory breast and armpit fat can become more noticeable when the arms are lowered or closed.
   For this reason, we check not only the front view, but also the closed-arm position, oblique view, and side view before deciding the treatment area.
3. Avoiding over-removal and indentation
   Removing accessory breast fullness can make the upper body look cleaner.
   However, if too much is removed, indentation or unevenness may occur.
   At AVAN TOKYO, we carefully evaluate skin thickness, fat volume, and the connection to the outer breast to remove fat in a natural and balanced way.
4. Designing the breast line after augmentation
   When fat transfer breast augmentation or Hybrid Breast Augmentation is performed, the outer breast line becomes especially important.
   By reducing the accessory breast and armpit fullness, the breast shape after augmentation can appear more refined.

Who may benefit from accessory breast liposuction?
Accessory breast liposuction may be suitable for patients who:
● Are considering arm liposuction
● Are concerned about armpit fat or accessory breast fullness
● Want to reduce thickness when the arms are closed
● Want to wear sleeveless clothing more confidently
● Want a cleaner outer breast line
● Are considering fat transfer breast augmentation
● Are considering Hybrid Breast Augmentation

Patients who are considering both arm liposuction and breast augmentation may achieve a more refined upper-body design by including accessory breast liposuction.

Frequently Asked Questions
Can accessory breast liposuction be performed with arm liposuction?
Yes, if indicated.
This combination works well because the arms, armpits, accessory breast area, and outer breasts can be designed as one continuous line.
Can it be performed with fat transfer breast augmentation or Hybrid Breast Augmentation?
Yes.
Accessory breast liposuction works well with breast augmentation because it can improve the outer breast and armpit contour.
Will removing the accessory breast area make the breasts look smaller?
In many cases, reducing accessory breast or armpit fullness can make the breast contour clearer and more refined.
However, for patients who want to keep some volume for professional or aesthetic reasons, we may design the treatment more conservatively.
Is there downtime?
Swelling, bruising, pain, firmness, and fibrosis may occur.
When combined with arm liposuction or breast augmentation, the downtime of each treatment area should be considered together.
Can accessory breast liposuction be performed alone?
Yes, depending on the condition.
However, we recommend evaluating the connection between the arms, armpits, and outer breasts before deciding the best treatment area.

AVAN TOKYO’s upper-body design
At AVAN TOKYO, we do not view liposuction or breast augmentation as isolated procedures.
For arm liposuction, we assess not only the arms, but also the shoulders, arm root, armpits, and accessory breast area.
For fat transfer breast augmentation and Hybrid Breast Augmentation, we assess not only breast size, but also the décolletage, outer breast, armpits, and connection to the arms.
To create a beautiful upper body, the following points are important:
● Slimness of the upper arms
● Clean armpit contour
● Reduced accessory breast unevenness
● Smooth outer breast line
● Natural line from the décolletage to the breast
● Overall body balance
At AVAN TOKYO, we design each treatment based on the patient’s body type, fat volume, skin quality, breast condition, and desired appearance.

Summary
Accessory breast liposuction is not simply a procedure to remove a small bulge near the armpit.
It is an important procedure for creating a smoother and more refined upper-body line from the arms to the armpits, accessory breast area, and outer breasts.
Arm liposuction alone may leave thickness around the armpit.
Breast augmentation alone may not improve the accessory breast or outer breast contour.
For this reason, patients considering arm liposuction, fat transfer breast augmentation, or Hybrid Breast Augmentation should also consider whether accessory breast liposuction is appropriate.
At AVAN TOKYO, we design the arms, armpits, accessory breast area, and outer breasts as one connected line to create a thin, smooth, and refined upper-body silhouette.

Risks and Complications
Swelling, bruising, pain, fibrosis, firmness, edema, contour irregularities, asymmetry, pigmentation, scarring, sensory changes, numbness, infection, hematoma, seroma, skin laxity, indentation from over-removal, and possible need for revision surgery.
When combined with fat transfer breast augmentation or Hybrid Breast Augmentation, additional risks include fat necrosis, palpable lumps, calcification, fat absorption, individual differences in fat retention, capsular contracture, implant displacement, and rippling.
