Why the Breast Crease Sometimes Needs to Be Lowered During Breast Augmentation

When most patients think about breast augmentation, they naturally focus on implant size. However, choosing an implant is only one part of the planning process.

For a breast implant to look balanced and natural, it must fit the patient’s breast in several directions. The breast needs to be wide enough for the implant, but it also needs enough space between the nipple and the crease beneath the breast.

In some patients, this distance is naturally short. When that happens, I may need to carefully lower the breast crease during surgery so the implant can sit in the proper position.

What Is the Inframammary Fold?

The inframammary fold is the natural crease where the lower breast meets the chest.

This crease helps define the bottom border of the breast. Its position affects the shape of the lower breast, the position of the implant, and the relationship between the implant and the nipple.

Although it may look like a simple line on the skin, the breast crease is supported by attachments beneath the skin. These attachments help hold the lower breast in position.

Why Does the Position of the Breast Crease Matter?

For an aesthetically balanced result, the implant should generally be centered behind the breast and nipple. In many patients, this means that approximately half of the implant sits above the level of the nipple and half sits below it.

If the natural breast crease is too high, there may not be enough space below the nipple for the implant. The implant may then sit too high relative to the nipple, making the nipple appear low or droopy even when the nipple itself has not moved.

Lowering the breast crease can create the additional space needed to center the implant more appropriately.

What Causes a Short Distance Between the Nipple and Breast Crease?

Some patients naturally have a short or tight lower breast. This is known as lower breast constriction.

Lower breast constriction can be mild and difficult to recognize. It may simply look like a short distance between the nipple and breast crease, or one breast may appear slightly tighter than the other.

More noticeable constriction can fall along the spectrum of tuberous breast deformity. Despite the name, this does not always mean that the breast has an obviously tubular appearance. The condition exists on a spectrum, and many patients have subtle features.

Possible signs include:

• A short distance between the nipple and the breast crease
• A high or tight breast crease
• Limited fullness in the lower part of the breast
• A narrow breast base
• A larger or more prominent areola
• Breast tissue pushing forward through the areola
• A noticeable difference between the two breasts

A patient does not need to have all of these features to have some degree of lower breast constriction.

How Do I Evaluate the Breast Before Surgery?

Before selecting an implant, I evaluate the patient’s breast width, tissue quality, skin stretch, nipple position, and the distance between the nipple and breast crease.

The nipple-to-crease distance is often measured while the lower breast tissue is placed on maximum stretch. This helps estimate how much room the existing tissue can provide once an implant is placed.

I also evaluate each breast separately. It is common for one side to be more constricted than the other. One breast may therefore require more adjustment, a different surgical release, or a different degree of fold lowering.

Breast asymmetry is normal, but identifying these differences before surgery allows for a more individualized plan.

Implant Fit Is About More Than Width

Breast implant planning often begins with the width of the patient’s breast. The implant should fit within the natural breast footprint and should not be excessively narrow or wide for the chest.

Width, however, is only one part of the equation.

The breast also needs enough vertical space for the implant. This does not mean simply measuring the straight height of the implant. The breast tissue must travel over the curved surface of the implant.

This curve creates an arc. A larger or more projecting implant will generally create a longer arc and require more tissue to cover the lower portion of the implant.

For this reason, two implants with a similar width can require different amounts of space below the nipple. The implant’s height, projection, shape, and volume all influence how it will fit within the breast.

Can the Smallest Implant Still Be Too Large for the Natural Breast Crease?

Yes.

In some patients, the natural breast crease is positioned so high that even a relatively small implant is too tall for the available space below the nipple.

This is an important point because simply choosing a smaller implant does not always solve the problem. The implant still needs to be positioned correctly behind the nipple.

If the crease remains too high, the implant may sit unnaturally high on the chest. The nipple may appear too low on the implant, and the lower breast may look tight or underdeveloped.

In these situations, carefully lowering the breast crease may be necessary even when the patient has selected a modest implant.

How Is the Breast Crease Lowered?

When the natural crease is too high, I can carefully release some of the tight tissue and create a new breast crease slightly lower on the chest.

The amount of lowering depends on several factors, including:

• The patient’s existing anatomy
• The degree of lower breast constriction
• The strength of the original breast crease
• The distance between the nipple and crease
• The implant’s height and projection
• The quality and stretch of the patient’s tissues
• Differences between the right and left breasts

The goal is not simply to create more room. The goal is to create the correct amount of room while maintaining control and support of the implant.

How Is the New Breast Crease Supported?

When I lower the breast crease, I will often reinforce the new fold with internal sutures. These sutures help define the new crease and support the implant in its planned position.

I may also use a surgical scaffold. Patients sometimes hear this described as an “internal bra.”

A surgical scaffold is a supportive material placed inside the breast to reinforce weakened or newly created tissue boundaries. It can provide additional support beneath the implant and along the new breast crease while the tissues heal.

A surgical scaffold is not necessary for every patient. I consider it when the tissues need additional support, when the fold requires more substantial adjustment, or when there is increased concern about implant movement.

The scaffold does not replace careful implant selection, precise surgery, or proper healing. It is an additional tool that may help support the surgical plan in appropriately selected patients.

Why Not Lower the Breast Crease as Much as Needed?

The breast crease cannot be moved without considering the strength of the tissues and the attachments of the original fold.

Whenever possible, I try to keep the amount of lowering conservative. In many patients, this means lowering the crease by approximately one to one and a half centimeters or less.

As the required lowering approaches two centimeters, particularly in a patient with a tight or strongly defined original fold, the risk of contour problems may increase. However, in some patients with severe breast constriction or tuberous breast deformity, the fold must be lowered more.

These measurements are not absolute rules. Every patient’s tissues are different, and the strength of the original crease can be just as important as the distance it needs to be moved.

What Is a Double-Bubble Deformity?

A double-bubble deformity occurs when the original breast crease remains visible after the implant and new crease have been positioned lower.

Instead of one smooth curve along the bottom of the breast, a second line or indentation may appear across the lower breast. The original crease creates one contour, while the implant and new crease create another.

Patients with a tight lower breast, a strongly defined original crease, or tuberous breast features may have a higher risk of developing this problem.

Careful release of the constricted tissue, conservative fold lowering, appropriate implant selection, fold reinforcement, and the selective use of a surgical scaffold may help reduce the risk. However, no surgical technique can eliminate every possibility of a double-bubble contour.

Often a double bubble deformity is further improved with a highly cohesive form-stable implant (commonly called "gummy bear" implants), which helps expand out the crease, scoring of the crease from the inside to help release the constriction and fat grafting which can help soften the crease and provide extra tissue buffer.

What Other Risks Are Associated With Lowering the Breast Crease?

Lowering the breast crease is a controlled and intentional part of many breast augmentation procedures, but it adds complexity to the operation.

Potential concerns include:

• The original crease remaining visible
• The implant settling lower than intended (commonly known as bottoming out)
• The new crease healing too high or too low
• Differences between the two sides
• A scar that does not sit perfectly within the final crease
• Changes in lower breast shape as the tissues stretch
• The need for revision surgery

These risks depend on the patient’s anatomy, tissue quality, implant selection, healing, and the amount of fold adjustment required.

Will Both Breasts Need the Same Amount of Adjustment?

Not necessarily.

Breast asymmetry is extremely common. One breast may have a shorter nipple-to-crease distance, a tighter lower breast, or a higher crease than the other.

If one side is more constricted, I may need to lower or release that side differently. The goal is not to perform identical steps on both breasts. The goal is to create the most balanced result possible.

Some natural asymmetry may remain after surgery. This is discussed during the consultation so that patients have realistic expectations.

Does Lowering the Crease Mean I Can Choose a Larger Implant?

Not automatically.

Lowering the breast crease should not be viewed as a way to force an oversized implant into a breast that cannot safely support it.

The implant still needs to match the patient’s breast width, tissue thickness, skin stretch, chest shape, and long-term tissue support.

In some cases, lowering the crease allows an appropriately selected implant to sit in the correct position. In other cases, choosing an implant with different dimensions may be the safer and more predictable option.

The surgical plan should be based on the patient’s anatomy rather than a desired implant volume alone.

What Should Patients Expect After Surgery?

After surgery, swelling can temporarily affect the position and shape of the breasts. The implants may initially appear high, firm, or uneven as the tissues begin to relax.

When the breast crease has been lowered or reinforced, following postoperative instructions is especially important. Patients may be asked to wear a specific support garment, avoid pressure on the new crease, and limit certain activities while the tissues heal.

The breasts will continue to change as swelling decreases and the implants settle. Final position and lower breast shape cannot be judged immediately after surgery.

Healing instructions vary depending on the procedure, implant position, tissue quality, and whether a surgical scaffold was used. Patients should follow the recommendations provided by their own surgeon.

Questions to Ask During Your Consultation

If you are considering breast augmentation, helpful questions may include:

• Is the distance between my nipple and breast crease long enough for the implant I am considering?
• Do I have any signs of lower breast constriction?
• Are my breast creases positioned at the same level?
• Will either breast crease need to be lowered?
• How much lowering do you anticipate?
• How will the new crease be supported?
• Would a surgical scaffold be helpful in my case?
• Am I at increased risk for a double-bubble contour?
• Would a different implant height or projection better fit my anatomy?
• What natural asymmetries are likely to remain after surgery?

The Bottom Line

Breast augmentation planning involves much more than selecting an implant size.

The implant must fit the width of the breast, but there must also be enough space between the nipple and breast crease for the implant to sit in a balanced position. When the lower breast is short or constricted, carefully lowering and reinforcing the breast crease may help create that space.

The decision depends on the implant’s dimensions, the position and strength of the natural crease, the amount of available tissue, and the differences between the two breasts.

Thoughtful planning is essential because lowering the crease too little can leave the implant sitting too high, while lowering it too far can increase the risk of implant movement or a double-bubble contour.

The goal is not to fit the largest possible implant. The goal is to select and position an implant that fits the patient’s anatomy and creates a balanced, natural-looking result.
