In May 2026, the Regional Medical Council of the State of São Paulo, Brazil, adopted a significant new patient-safety measure: elective cosmetic plastic surgeries expected to last six hours or longer may no longer be scheduled as a single operation.

Although this rule applies only in São Paulo, it has relevance far beyond Brazil. Brazil performs more cosmetic surgical procedures than any other country, according to the International Society of Aesthetic Plastic Surgery. When a major medical regulatory body within such an influential plastic surgery community places a firm limit on operative time, it underscores an important question every patient considering combined surgery should ask:

How long will my operation take, and what is my surgical team doing to minimize unnecessary time under anesthesia?

At Washington Women Plastic Surgery, this conversation resonates deeply with us. Our practice was founded around a distinctive two-surgeon model designed to combine efficiency with real-time collaboration, shared decision-making, and meticulous attention to detail.

Why Operative Time Matters

No specific number of hours suddenly makes an operation unsafe. Surgical risk depends on many factors, including the patient’s health, the procedures being performed, blood-clot risk, the surgical setting, and the experience of the surgical and anesthesia teams.

Nevertheless, research consistently identifies longer operative time as an important risk factor.

A large study examining more than 100,000 plastic surgery cases found that increased operative time was independently associated with surgical-site infections and unplanned reoperations. Procedures lasting more than 10 hours had approximately three times the reoperation risk of procedures lasting less than six hours.

A separate systematic review found that the likelihood of complications increased as operative time increased, with each additional 30 minutes associated with an estimated 14% rise in the probability of complications.

Longer operations may also mean greater exposure to anesthesia, prolonged immobility, heat loss, fluid shifts, and increased risk of blood clots. This does not mean combined procedures are inherently unsafe or that every longer procedure should be avoided. It means the decision to combine operations must be individualized and made thoughtfully.

Sometimes, the safest recommendation is to divide a surgical plan into separate stages. In carefully selected patients, however, combined procedures may be performed efficiently and appropriately—particularly when the surgical team is structured to work collaboratively.

What Our Two-Surgeon Approach Really Means

When we say that two surgeons operate together, we do not mean that one surgeon performs the operation while the other observes, assists occasionally, or closes the incisions.

Our cases are performed as a genuine partnership between two board-certified plastic surgeons who remain actively involved throughout the operation.

We plan the procedure together, review the surgical markings together, and continually evaluate the operation from two independent perspectives. When the procedure allows, we work simultaneously on different areas of the body rather than completing every step sequentially.

During breast surgery, for example, we may operate at the same time—one surgeon working on each breast. This can make the breast portion of a combined procedure substantially more efficient while also allowing us to compare shape, position, volume, and symmetry throughout the operation.

During an abdominoplasty or extensive body-contouring procedure, we divide and coordinate the work according to the needs of the case. While one surgeon addresses abdominal-wall repair or closure, the other may work on liposuction, tissue contouring, or another portion of the operation. We then come together at critical stages to evaluate the overall result and make refinements.

The precise division of work varies because every operation is different. What remains consistent is that both surgeons are engaged, both are accountable, and both bring their full training and judgment to the patient’s care.

Efficiency Without Rushing

Shortening an operation should never mean rushing through it.

Our goal is to eliminate unnecessary sequential time—not to compromise technique or attention to detail. Two experienced surgeons can perform appropriate portions of an operation concurrently while maintaining a deliberate and coordinated approach.

This structure may allow us to complete a combined procedure in less time than would be required for one surgeon to perform every step alone. The expected duration still depends on the patient’s anatomy, surgical plan, complexity, and findings during the operation, and we discuss those considerations before surgery.

For us, efficiency is not about fitting more cases into a day. It is about making purposeful use of the patient’s time under anesthesia.

Two Independent Perspectives in the Operating Room

Plastic surgery involves countless decisions that cannot be reduced to a formula. Surgeons continually assess tissue quality, tension, proportion, contour, symmetry, and how one area relates to another.

Our two-surgeon model places an experienced colleague beside each of us for those decisions.

We evaluate one another’s markings before the operation begins. During surgery, we openly discuss how much tissue to remove, whether additional contouring is appropriate, how the incisions are coming together, and whether the original plan should be modified based on what we see.

This creates a form of real-time peer review. Each patient benefits from two board-certified plastic surgeons examining the work while there is still an opportunity to refine it.

Importantly, ours is an equal partnership. Neither surgeon is simply carrying out instructions from the other. We trained together, share a common foundation in plastic surgery, and have developed a coordinated operative rhythm through years of working side by side. At the same time, we retain independent perspectives—and we believe that combination is one of the greatest strengths of our practice.

Can Two Surgeons Guarantee a Safer Operation or Better Result?

No surgical model can eliminate risk or guarantee a particular outcome.

Two surgeons do not make every combination of procedures appropriate, nor do they make careful patient selection any less important. We still evaluate each patient’s health, medical history, body mass index, blood-clot risk, nicotine exposure, medications, prior surgeries, and overall surgical goals.

If we believe a proposed operation would be too long or place too much physiologic stress on a patient, we recommend staging it—even when that means two operations and two recovery periods.

Our collaborative approach is one component of a broader safety process that also includes:

  • Thoughtful patient selection and medical clearance
  • An individualized assessment of blood-clot risk
  • Surgery in an appropriately accredited facility
  • A qualified anesthesia professional dedicated to the patient throughout the procedure
  • Careful postoperative monitoring and follow-up
  • A willingness to limit or stage surgery when the proposed combination is not appropriate

The objective is not to perform the greatest number of procedures at once. It is to create a plan that balances the patient’s goals with sound surgical judgment.

Questions to Ask Before Combined Plastic Surgery

Patients considering a mommy makeover or another combined procedure should feel comfortable asking:

  • How long is my operation expected to take?
  • Which procedures are being combined, and why?
  • Would staging the procedures be safer for me?
  • Who will be performing each portion of the operation?
  • Will my surgeon be present and actively operating throughout the entire case?
  • Where will my surgery take place, and is the facility accredited?
  • Who will administer and monitor my anesthesia?
  • How will my individual blood-clot risk be evaluated and managed?

A responsible surgeon should be able to answer these questions clearly and explain how the plan was tailored to your health, anatomy, and priorities.

Collaboration is Part of Our Practice’s Foundation

Our two-surgeon model was not developed as a marketing concept. It grew naturally from the way we trained, the way we think, and the standard of care we wanted to provide when we founded Washington Women Plastic Surgery.

We believe patients benefit when two experienced surgeons can plan together, operate together, question one another, and refine a result together. The potential reduction in operative time is meaningful, particularly during combined procedures, but it is only one part of the benefit.

The deeper advantage is collaboration: two board-certified plastic surgeons, equally invested in the patient, bringing two sets of trained eyes, two independent perspectives, and one shared commitment to the safest and best-planned operation possible.
