Reconstruction of the Pediatric airway with an open stented tracheotomy tube

Reconstructive techniques for the stenotic Pediatric airway have greatly enhanced the otolaryngologists ability to decannulate the tracheotomy-dependent child. Stents have played an important role in this process by both maintaining the reconstructed lumen and acting as a scaffold. However, decannulation is often not achieved after the first surgical intervention with some patients requiring two, three or more procedures. In an effort to improve upon the design of today's stents, an open stented tracheotomy tube was evaluated at our institution. This stent is designed to provide advantages of immediate postoperative voice and nutrition, and ease of evaluation, as well as to provide for safe and adequate healing. Four patients underwent laryngotracheal reconstruction with this stent over a 10-month period. All patients could vocalize and eat immediately postoperatively but recalcitrant granulation tissue and restenosis has prevented decannulation in three of the cases. The experience with this stent exemplifies the persistent difficulties of stent use in Pediatric airway reconstruction. It also points out that progress is still needed in current reconstructive techniques as well as in the development of new techniques.
