A breast augmentation incision changes more than where the scar sits. It determines the surgeon's access to the implant pocket, which tissues are crossed, and how a future revision might be approached. The breast fold, areolar edge, and armpit each have advantages and limits. The best choice depends on breast anatomy, implant dimensions, and the surgical work required, rather than on the idea that one scar location is always best.
Why is the incision under the breast fold commonly used?
An inframammary incision provides direct access to the pocket and lower breast boundary. That can help with implant positioning and control of the fold. It generally avoids an approach through the central gland, although no incision can eliminate the risks of altered sensation, infection, or future implant complications.
The scar is often concealed in the fold while standing, but it can be visible when lying down or lifting the breast. An existing fold is not always the final fold position. Implant size, chest shape, and the amount of lower breast tissue affect where the incision should be planned.
The ASPS augmentation procedure overview describes incision selection as part of an individualized operation. A small external scar is only one consideration; the access must be sufficient to place the chosen device safely.
When does an incision around the areola make sense?
A periareolar incision follows part of the border between the areola and surrounding skin. The color transition may make the scar less conspicuous, but it does not make the scar invisible. Areolar diameter can limit access, especially with a larger implant.
The route can cross glandular tissue and ducts depending on technique. Milk supply and nipple sensation therefore belong in the conversation, particularly for someone planning future breastfeeding. A scar near the areola does not prove that ducts will be divided or that breastfeeding will be impossible; the actual dissection matters.
| Incision | Where the scar sits | Main tradeoff to discuss |
|---|---|---|
| Inframammary | At or near the breast fold | Direct access, with a scar visible in some positions |
| Periareolar | Along part of the areolar border | Color blending, but access and gland or duct considerations |
| Transaxillary | Within the armpit region | Avoids an initial breast scar, but access and later revision can be different |
What does an armpit incision trade?
Transaxillary augmentation reaches the pocket from the armpit. Dr. Castro uses this approach when indicated. Suitability depends on anatomy, implant selection, and what the pocket needs, including whether another breast procedure is required.
The armpit scar can be visible with raised arms. The approach does not make surgery scarless or eliminate breast sensation risks. A later exchange or correction may require an incision on the breast even if the original augmentation used the armpit. A patient should understand that possibility before choosing the first incision mainly to avoid a breast scar.
Does the incision determine capsular contracture risk?
Capsular contracture is tightening of the scar capsule around an implant. Bacterial exposure and inflammation are among the factors discussed in its development, and routes through breast tissue may affect exposure. However, incision comparisons are influenced by technique and other variables; no incision guarantees prevention.
The capsular contracture article explains the complication itself. Incision choice also differs from implant pocket choice: the same external access can sometimes reach different tissue planes.
What if I also need a lift or a future revision?
A lift requires its own skin incisions. Choosing an armpit access point for an implant cannot remove the scars needed to reposition loose breast tissue. Implant exchange, capsule treatment, or pocket repair may also change the preferred access later. Implant dimensions and fill, discussed in the implant characteristics guide, belong in this planning discussion.
Choose access and scar placement together
For breast augmentation, ask to see where each reasonable incision would sit on your body and what work it allows. Include breastfeeding goals, scar history, and the possibility of future surgery. The useful comparison is between complete surgical plans, not isolated scar photographs.
