Direct-to-Implant Breast Reconstruction: What You Need to Know

If you're undergoing a mastectomy and want breast reconstruction with an implant, you may have the option of direct-to-implant reconstruction — placing the final implant at the same time as the mastectomy, rather than going through a two-stage process with a tissue expander first.

If you've never heard the term, here's the two-stage process in plain language.

A tissue expander is a saline (salt water) implant with a gummy port built into it. Instead of placing your long-term implant at the time of the mastectomy, the surgeon places the expander, either deflated or only partially inflated.

You're then given a couple of weeks to heal. After that, you come into the office, where the expander is slowly inflated through the port over a series of visits until it reaches the desired size.

Finally, you go back to the operating room for a second procedure, where the expander comes out and your actual implant goes in.

That's two stages. Direct-to-implant does it in one: the long-term implant goes in during the same surgery as the mastectomy.

• Mastectomy (bilateral): typically 3–4 hours
• Implant reconstruction: about 1–1.5 hours per side
• Total for bilateral mastectomy + reconstruction: approximately 5–6 hours

Dr. Killeen receives many DMs from patients who were told direct-to-implant isn't an option. Here are the common reasons — and the reality behind them:

If the tissue looks terrible at the end of the mastectomy — poor perfusion, bad SPY imaging numbers — it's not safe to place a permanent implant. Damaged tissue may need to be removed, leaving the skin too tight around the implant. A tissue expander (which can be deflated) is easier to manage in this scenario.

The reality: This is largely a surgeon skill issue. With excellent mastectomy surgeons, you should almost never see horrible flaps. If your plastic surgeon says they'll "make the decision in the operating room," they may be hinting that the mastectomy surgeon isn't great. Your mastectomy surgeon choice is as important as your plastic surgeon choice.

In some regions, radiation oncologists tell patients they can't have an implant in place during radiation. This is not true. Dr. Killeen's team does it routinely. In fact, it's often better to get the implant in before radiation rather than operating afterward — the results tend to be better with fewer contracture issues.

Larger breasts have higher rates of mastectomy flap necrosis according to the best studies. Some surgeons default to a tissue expander to be safer, since necrosis is easier to manage with an expander that can be deflated.

Droopy breasts can also have higher necrosis rates. Some surgeons use this as a reason for tissue expanders, though Dr. Killeen doesn't necessarily agree. A lift can also be performed at the time of mastectomy — it increases complication risk somewhat, but it's definitely possible. Ask your surgeon if this is an option for you.

This is the real reason in many cases. A lot of surgeons were trained on two-stage reconstruction — tissue expander first, then implant swap — and that's what they're comfortable with. Dr. Killeen was trained on direct-to-implant, has done it for a long time, and very rarely needs revisions on these patients.

The reasons above are about you: your tissue, your anatomy, your radiation plan, your surgeon's training. This one is different, and patients deserve to understand it.

Some hospital systems don't allow direct-to-implant at all. The stated reason is usually that they have bad outcomes with it, and that part is often true. Their complication rates really are high.

Here's the part they don't say out loud:

Dr. Killeen is a general surgeon as well as a plastic surgeon, and she's blunt about where the problem sits: general surgery colleagues need to treat the mastectomy with the same care and consideration that plastic surgeons give the reconstruction.

There should not be such a wide gulf between good and bad mastectomy surgeons. As covered in the questions to ask your breast surgeon, the surgeons she works with have mastectomy flap necrosis rates under 5%, while other places run over 30%. In her words: "That is unacceptable. Women deserve better."

And it explains the pattern in the data. Immediate reconstruction has higher complication rates than delayed, even though the plastic surgeon is doing the identical operation either way. The mastectomy is the variable.

What That Means for You as a Patient

Real candidacy limits do exist, and they're the ones listed above: very large breasts, or adding a lift at the same time, which raises risk even though it's still done. Nipple sparing shouldn't matter.

But a system-wide ban is not a candidacy question. As Dr. Killeen puts it:

It isn't the plastic surgeons. And if the general surgeons at an institution are producing outcomes bad enough that the system has banned the better reconstruction, that's worth sitting with, because those are the surgeons who would be doing your cancer operation, not just affecting your reconstruction.

Her own framing on saying this out loud: "I'm sorry to be a jerk about it, but I'm really tired of tiptoeing around the truth." General surgery in the United States has a real problem with mastectomy quality, and it needs to be better.

When possible, direct-to-implant offers significant advantages:

• One fewer surgery — no second procedure to swap the expander for an implant
• Easier recovery — no office visits for expansions
• More comfortable — you avoid living with a tissue expander, which can be painful and oddly shaped

Full disclosure before this section: Dr. Killeen does essentially all direct-to-implant reconstruction, so her honest starting position is that nearly everybody is a candidate. That bias is worth stating out loud, because there are real situations where an expander is the better answer.

This is the flip side of reason #1 above, and it deserves saying directly rather than only as a criticism.

If a surgeon is working with a general surgeon whose flaps are inconsistent, meaning the skin is often not healthy at the end of the mastectomy, then reaching for an expander is the right call for the patient. If you lose skin, that is much easier to manage with an expander, and sometimes doesn't even require a return to the operating room.

The expander isn't the problem in that scenario. It's the correct adaptation to the problem.

Here's a scenario patients rarely hear about. A patient is having radiation, and the ultimate plan is an autologous reconstruction, typically a DIEP flap. Some surgeons place a tissue expander purely to keep the skin expanded during radiation, then remove it when the DIEP is performed.

Dr. Killeen would still use an implant in that interim slot rather than an expander. There's also a practical argument for the patient: implants are less expensive than tissue expanders, so in that situation an implant is the better financial outcome for you.

You'll hear that expanders are preferable if you want to come out noticeably larger or smaller than you started. Dr. Killeen doesn't agree with that one either.

She places implants larger than the mastectomy specimen routinely, and those patients do fine — a finding she and her partner since published, comparing upsized and downsized direct-to-implant reconstructions and finding no penalty for going larger. Going smaller doesn't require an expander either; you can do a lift at the same time, or not.

(The full range of size outcomes is here — smaller, the same, larger, or more lifted.)

Some surgeons are more comfortable with tissue expanders, and that is literally all they use. That's not a disqualification.

The same principle runs in the other direction. Dr. Killeen is very comfortable going direct-to-implant and skipping the expander, and that is almost certainly what she'd recommend to you — which is itself a form of surgeon preference, honestly labeled.

The useful conclusion:

So the question to bring to a consultation isn't "which technique is correct." It's "which do you do most, and why that one for me?"

Your reconstruction results depend heavily on the quality of the mastectomy. Here's a tip from one of Dr. Killeen's patients:

Call a plastic surgeon's office anonymously and say you're looking for a mastectomy surgeon and want that plastic surgeon to do your reconstruction. Ask who they recommend for the mastectomy. You'll likely get the best general surgeons in town — because plastic surgeons know exactly whose work gives the best results and whose doesn't.

Direct-to-implant reconstruction saves you a surgery, shortens your recovery, and avoids the discomfort of tissue expanders. If you've been told it's not an option, it's worth understanding why — and whether seeking a second opinion with a surgeon experienced in direct-to-implant could change the plan.

And if the answer you get is that the entire system doesn't offer it, understand what that's telling you about that system's mastectomy outcomes. A second opinion somewhere else entirely may be the more useful move.
