Narrowing and weakness of the trachea can occur and are often difficult to repair. There have been two traditional means of reconstructing a damaged trachea, but both techniques have limitations. Lee Smith, MD, chief of pediatric otolaryngology at Cohen Children’s Medical Center and David Zeltsman, MD, chief of thoracic surgery at Long Island Jewish Medical Center, both part of the North Shore-LIJ Health System, came to Mr. Goldstein and Daniel A. Grande, PhD, director of the Orthopedic Research Laboratory at the Feinstein Institute, and asked if 3D printing might offer a solution. Drs. Smith and Zeltsman originally surmised that incorporating 3D printing and tissue engineering to grow new cartilage for airway construction might be possible in ten to 20 years.
