{Reference Type}: Case Reports {Title}: A new technique for neonatal Jeune syndrome: External thoracic expansion. {Author}: Temel U;Akgül AG; {Journal}: Turk Gogus Kalp Damar Cerrahisi Derg {Volume}: 29 {Issue}: 2 {Year}: Apr 2021 {Factor}: 0.704 {DOI}: 10.5606/tgkdc.dergisi.2021.19731 {Abstract}: Jeune syndrome is a rare form of skeletal dysplasia characterized by a narrow, bell-shaped chest (thoracic cage), and typical phalangeal and pelvic bone deformities. Chest expansion is impaired by the short, horizontally positioned ribs, resulting in alveolar hypoventilation and eventually neonatal-infantile death in most cases. External distraction with sternoplasty is a new technique for the treatment of Jeune syndrome, which was firstly used by our team on a newborn by placing a sliding finger fixator which was designed for ulnar lengthening. We believe that this approach can be life-saving in neonates with improved and widespread usage.
