You’ve seen the headlines. They usually pop up every few months—two tiny babies, often joined at the head or the chest, heading into a 24-hour surgery with a team of fifty doctors. It’s high-stakes drama. But honestly, the media usually disappears once the "miracle" surgery is over. We rarely talk about the grueling reality of before and after conjoined twins separated.
It’s complicated.
Most people think of separation as a finish line. In reality? It’s just a different starting block. For the parents, the doctors, and the twins themselves, the journey involves a radical recalibration of what it means to be an individual.
The Pre-Op Reality: Living as One
Before any scalpels touch skin, life is a logistical puzzle. Imagine trying to diaper two babies who are fused at the pelvis. Or feeding one baby while the other is trying to sleep, but they share a circulatory system, so the caffeine or sugar from one's milk might be affecting the other’s heart rate.
Conjoined twins occur in roughly 1 out of every 50,000 to 200,000 births. It’s rare. Because it’s so rare, the "before" phase is often defined by a series of high-intensity diagnostic tests. Doctors at institutions like the Children's Hospital of Philadelphia (CHOP) or Great Ormond Street in London spend months using 3D printing and VR to map out shared organs.
Take the case of Abby and Erin Delaney. They were craniopagus twins—joined at the head. Before their separation in 2017, their parents had to manage the sheer physical weight of two growing toddlers who couldn't sit up independently because of how they were attached. Every movement was a coordinated dance.
The "before" isn't just medical. It’s psychological. Parents have to grapple with the "sacrifice play." Sometimes, one twin is stronger. Sometimes, separating them means one will almost certainly have a lower quality of life so the other can survive. It’s a heavy, almost impossible burden that doesn't get enough credit in the news cycles.
The Surgery: The Great Divide
The actual separation is less of a surgery and more of a marathon. We’re talking 12, 20, sometimes 50 hours straight.
It’s not just about cutting. It’s about reconstruction.
When you look at the before and after conjoined twins separated timeline, the surgery is the pivot point where "we" becomes "I." Surgeons have to split shared livers—the only organ that can actually regenerate—or, in much more terrifying cases, split shared brain tissue or major blood vessels like the superior sagittal sinus.
In 2022, Brazilian twins Arthur and Bernardo Lima were separated after seven surgeries. They were nearly four years old. That’s old for separation. Their brains were fused. The lead surgeon, Dr. Noor ul Owase Jeelani, used VR headsets to practice the surgery with doctors across the globe. Think about that. Surgeons in London and Rio wearing headsets, "walking through" the boys' shared anatomy before making a single cut.
The "After": The First Time They See Each Other
The most emotional part of the before and after conjoined twins separated experience is the first encounter. For their entire lives, they’ve been side-by-side or top-to-bottom. They’ve felt each other’s heartbeats and kicks.
Then, suddenly, there’s a gap.
When the Bentley twins (Adeline and Knatalye) were separated, the nurses noticed a shift in their vitals when they were finally placed in separate cribs. There’s a period of sensory shock. The physical "other" that was always there is gone.
The Physical Toll of Independence
The "after" is usually marked by:
- Dozens of follow-up plastic surgeries to close skin gaps.
- Intensive physical therapy to build muscles that were never used.
- Learning to balance. If you've spent two years leaning left to compensate for your twin, your spine doesn't just straighten out overnight.
- Neurological adaptation. The brain has to re-map where the body ends.
When Separation Isn't the Goal
It’s a misconception that every pair of conjoined twins wants to be separated, or that their parents want it for them. You’ve probably heard of Abby and Brittany Hensel. They are dicephalic parapagus twins, meaning they have two heads but share a body.
Separation was never a viable option for them because they share almost every vital organ below the shoulder. But more than that, they’ve built a life as a duo. They drive. They teach. They’ve navigated the world as a singular unit.
For them, the "after" of a separation would likely be a lower quality of life or death. This is the nuance that often gets lost in the "medical miracle" narrative. Sometimes, the best medical outcome is staying together.

The data is sparse because the sample size is so small. But we know that many separated twins go on to lead incredibly "normal" lives. They go to school, they date, they find hobbies.
But they often carry the scars—literally and figuratively.
Take the case of Kendra and Maliyah Herrin, separated in 2006. They each have one leg. They grew up using prosthetic limbs and became famous on social media for showing their lives. They are thriving, but their "after" involves a lifetime of medical maintenance. They deal with kidney issues and scoliosis.
The medical community is getting better at this. Thanks to 3D imaging, we aren't "flying blind" anymore. We can predict which blood vessels will cause a stroke and which can be safely cauterized.
Critical Actionable Insights for Families and Advocates
If you are following a case or are part of a support network for families facing this, understand that the "miracle" is just the beginning.
- Prioritize Post-Op Neuroplasticity: The brain’s ability to rewire itself after separation is peak in the first 6 months. Physical therapy isn't just for muscles; it's for the brain to understand its new boundaries.
- Mental Health is Non-Negotiable: For the parents, the PTSD of the "before" and the surgery is real. For the twins, "separation anxiety" is literal. Accessing child psychologists who specialize in body dysmorphia or trauma early on is vital.
- Logistical Planning: The financial "after" is staggering. Insurance rarely covers the full extent of the decades of reconstructive work needed. Crowdfunding and medical grants are usually necessary components of the long-term plan.
- Respect Autonomy: As twins age, their feelings about their separation may evolve. Open communication about their medical history helps them own their story rather than feeling like a medical curiosity.
The journey of before and after conjoined twins separated is a testament to human resilience and surgical brilliance. It’s a move from a shared existence to an individual one, but that shared history never really goes away. It’s written in the scars and the way they still reach for a hand that used to be right there.
