At Georgia Tech, a groundbreaking innovation in biotechnology has brought new hope to children suffering from a rare and potentially life-threatening birth defect of the windpipe. In partnership with Children’s Healthcare of Atlanta, Georgia Tech researchers have developed a 3D-printed tracheal splint that has given a 4-year-old boy, Justice Altidore, a chance to lead a normal life. Thanks to this life-saving treatment, Justice has begun preschool, full of energy and enthusiasm, no longer held back by the severe condition that once restricted his breathing.
Justice was born with tracheomalacia (TM), a condition that affects approximately 1 in 2,100 children, according to the Cleveland Clinic. TM is the most common inherited defect of the trachea, or windpipe, and occurs when the cartilage supporting the trachea is weak or floppy. This causes the walls of the windpipe to collapse, making it difficult for affected children to breathe. In severe cases, children with TM experience labored breathing, frequent respiratory infections, and may require mechanical ventilation to support their breathing.
Traditional treatments for TM have often been insufficient, and for many children, early years are fraught with health complications and a diminished quality of life. The introduction of the 3D-printed tracheal splint has provided a novel and highly effective solution for children like Justice. The splints, made from bioabsorbable materials, are designed to hold the trachea open, allowing the child to breathe more easily. Over time, the splint supports the development of the windpipe’s cartilage, and as the trachea strengthens, the splint is gradually absorbed by the body.
Justice Altidore’s treatment was part of an FDA-approved expanded access trial overseen by Dr. Kevin Maher, a pediatric cardiologist, and Dr. Steven Goudy, a pediatric otolaryngologist at Children’s Healthcare of Atlanta. Justice was one of four children who received custom-designed tracheal splints during the trial. According to Dr. Maher, the results have been transformative: “All four children have seen significant improvements in their respiratory capabilities.” These positive outcomes offer a glimpse of a new era of care for children with severe respiratory conditions.
The use of 3D printing in medical applications is not entirely new, but its role in treating tracheomalacia is particularly groundbreaking. In fact, Georgia Tech’s 3D-printed tracheal splints are not the first instance of 3D printing technology being used to aid tracheal recovery. Earlier this year, a biotech company became the first in the world to produce a bio-3D-printed windpipe that was successfully transplanted into a human body.
In March, the Seoul-based company T&R Biofab made headlines for a revolutionary medical procedure performed at St. Mary’s Hospital in South Korea. A woman in her 50s, who had lost part of her trachea during thyroid surgery, received the world’s first successful transplant of a bio-printed windpipe. The trachea was created using nasal stem cells and cartilage cells obtained from other patients. These cells were then combined with polycaprolactone (PCL) for structural support, as well as a special bio-ink made from living cells. The bio-ink allowed for the creation of a windpipe that not only matched the patient’s anatomy but also had the potential to integrate and function like natural tissue.
T&R Biofab’s achievement marked a significant advancement in the field of regenerative medicine. The company’s CEO noted that the bio-printed windpipe had been a decade in the making, with years of research and development culminating in this world-first procedure. The patient’s recovery has been closely monitored, and the transplant’s success has sparked global interest in the potential of bio-printed organs.
Both Georgia Tech’s 3D-printed tracheal splints and T&R Biofab’s bio-printed windpipe represent remarkable progress in the field of bioprinting and personalized medical care. The success of these treatments demonstrates the potential of combining cutting-edge technology with medical innovation to solve some of the most challenging health conditions. Dr. Goudy, reflecting on Justice’s case, remarked, “What we are witnessing is the future of healthcare – personalized solutions that allow us to address specific needs in ways we never thought possible before.”
As research continues, the hope is that these life-saving technologies will become more widely available to children and adults around the world. For now, Justice Altidore’s story stands as a testament to the power of innovation, a reminder that with perseverance and ingenuity, even the most complex medical challenges can be overcome.
