The three incision options in breast augmentation, and how surgeons choose

Every breast augmentation begins with a decision that gets far less patient attention than implant size: where the incision goes. There are three established options, and while all three can produce excellent results in the right hands, they are not interchangeable. Each carries its own trade-offs in scar visibility, surgical control, and complication risk, and the published data increasingly favors one of them for most patients.

The inframammary fold: the modern default. The inframammary incision sits in the crease beneath the breast, typically measuring four to five centimeters. It is the most commonly used approach in the United States, and for defensible reasons. It gives the surgeon direct, well-lit access to the pocket where the implant will sit, which means more precise control over placement and bleeding. It accommodates any implant type or size, including the cohesive gel devices discussed in our piece on implant shapes and fill. And several large studies associate it with the lowest rates of capsular contracture among the three approaches, likely because the implant travels a shorter, cleaner path to the pocket. The scar itself hides in the fold, invisible in bras and swimwear and usually faded to a fine line within a year.

The periareolar approach: concealment with caveats. The periareolar incision follows the lower border of the areola, where the color transition camouflages the scar. When it heals well, it can be the least noticeable of the three. The caveats are meaningful, though. The incision passes closer to milk ducts and nerves, and some studies report higher rates of nipple sensation changes and a somewhat higher likelihood of capsular contracture, possibly from bacterial exposure along the duct system. The size of the areola also limits the size of implant that can pass through the opening. Surgeons who favor this approach tend to reserve it for patients having a simultaneous areola adjustment or a combined procedure such as the augmentation-lift decisions covered in our comparison of augmentation and mastopexy.

The transaxillary route: no scar on the breast at all. The transaxillary incision hides in a natural crease of the armpit, leaving the breast itself unmarked. Modern versions use an endoscope, a small camera, to guide pocket creation, which improved precision considerably over the blind dissection of earlier decades. The trade-offs: it is technically more demanding, it is harder to fine-tune the fold position from above, and if a revision is needed years later, the surgeon usually cannot reuse the armpit route and must make a new incision anyway. It remains a reasonable choice for patients with strong feelings about breast scars, particularly with smaller implants.

What about the belly button? A fourth approach, the transumbilical or TUBA technique, tunnels an empty saline implant from the navel up to the chest. It never achieved mainstream adoption, works only with saline devices, and offers limited control. Most academic surgeons consider it a curiosity rather than a standard option, and implant manufacturers generally do not support it in their warranty language.

How the decision actually gets made. In practice, the incision conversation is a negotiation among four factors: the implant you have chosen, your anatomy, your scarring history, and your surgeon's experience. Silicone implants above a certain volume effectively require the fold incision. A history of keloid or hypertrophic scarring changes the calculus about where a scar can be best hidden and treated. And a surgeon's complication rates with their preferred approach usually beat their rates with an unfamiliar one, which is why boards-certified surgeons will often state a strong preference rather than presenting a neutral menu. That preference is worth probing rather than accepting silently. Ask how many of each approach they perform in a year, and how their contracture and reoperation rates compare. The screening framework in our guide to pre-surgery questions applies directly here.

The takeaway. For most patients choosing silicone implants today, the inframammary fold incision is the evidence-backed default: best access, lowest measured contracture risk, and a scar that stays hidden. The other approaches are legitimate tools for specific situations rather than equal alternatives. The right question is not which incision is best in general, but which is best for your implant, your anatomy, and your surgeon's hands.
