Endoscopic management of a prolapsed posterior costal cartilage graft in laryngotracheal reconstruction.

Laryngotracheal reconstruction is the standard of care for management of high grade pediatric laryngotracheal stenosis. One of the complications of a reconstruction with a posterior costal cartilage graft is graft prolapse. Typically, a revision laryngotracheal reconstruction will be needed to correct this complication. We describe a case in which a non-invasive endoscopic approach using laser was undertaken for a prolapsed posterior costal cartilage graft in a child who had undergone an anterior-posterior costal cartilage laryngotracheal reconstruction for Grade 3 stenosis. This, according to our knowledge, has not been previously described and provides an alternative to revision surgery.
