It's being hailed as a true miracle birth, a risky procedure was completed successfully for the first time at the Nebraska Medical Center in July. Tuesday, doctors and the parents shared their amazing story.

A team of 34 doctors worked on the procedure, called "EXIT" or an ex-utero intrapartum treatment. The team partially delivered a baby girl through C-section, who had a tumor in her mouth. Doctors were concerned the tumor would keep her from breathing on her own, but months of planning paid off and resulted in a healthy baby.

Tuesday, Haylee Hanson's family looked through pictures taken on her birthday inside the operating room. They witnessed just what a miracle she is.

On July 29, Megan Hanson, Haylee's mother, was taken in for a scheduled cesarean section. It was the plan since Megan was just 22 weeks pregnant, and an ultra sound revealed a problem.

"They found a mass that appeared to be close to the lips and possibly involving the airway for baby Haylee," said Dr. Teresa Berg, a maternal-fetal medicine doctor at the Nebraska Medical Center.

"It was quite the pregnancy, go from excited that our baby's finally going to be here, but yet scared to death because we don't know what's going to happen," said Megan.

During the delivery, dozens of surgeons, doctors, and nurses filled the operating room. First Haylee's head was exposed, but she remained connected to her umbilical cord, and her mother's oxygen.

Then doctors established an airway, and finished the delivery. "If she hadn't been born under these controlled circumstances and there was a delay in getting the airway established, Haylee would have been at risk for things like cerebral palsy, developmental disorders, and possibly even death," said Dr. Ann Anderson-Berry, a neonatologist from Nebraska Medical Center.

Haylee's benign tumor was surgically removed days later.

Dan Hanson says to see all the medical professionals who helped his daughter is overwhelming. "There was a lot of emotions, and also there was a calmness about us, that we were presented with, we have to thank the Lord above for that and confidence in all the doctors and the team that was around us."

Haylee is doing well. She will undergo more surgery in the months ahead to repair the roof of her mouth, where the tumor was removed.

For now, the focus is on something else. "We're just anxious to get her home and start our complete family," said Megan.

The exit procedure is very uncommon, only about 100 cases have been documented in the United States. Although this was the first for the Nebraska Medical Center, Children's Hospital and Medical Center says they've completed six of the procedures in the last ten years.
