Laryngotracheal reconstruction in infants and children: Are single-stage anterior and posterior grafts a reliable intervention at all pediatric hospitals?

ObjectiveTo review outcomes of pediatric laryngotracheal stenosis treated by single-stage laryngotracheal reconstruction with anterior and posterior cartilage grafts and compare decannulation rate for single-stage laryngotracheal reconstruction with rates published at larger (>200 beds) pediatric tertiary care hospitals.MethodsA 4-year retrospective chart review (2004–2008) of all patients undergoing procedures coded with 2008 CPT codes 31582 (laryngoplasty for laryngeal stenosis with graft or core mold, including tracheotomy) and 31587 (laryngoplasty, cricoid split) for a pediatric, tertiary-care hospital. Interventions were single-stage laryngotracheal reconstruction with anterior and posterior cartilage grafts, and the main outcome measure was the decannulation rate after single-stage laryngotracheal reconstruction.ResultsWe identified 44 patients with subglottic stenosis, of whom 13 underwent single-stage laryngotracheal reconstruction with anterior and posterior cartilage grafts. The mean age at surgery was 2.2 years (range, 5 months to 4 years). Twelve of 13 children had Cotton-Myer grade III stenosis. Ninety-two percent (12 of 13) of children remain decannulated. The mean follow up was 52 months.ConclusionsSingle-stage laryngotracheal reconstruction with anterior and posterior cartilage grafts appears to be a safe and effective technique for managing patients with high-grade subglottic stenosis at intermediate size children's hospitals. Our overall decannulation rate of 92% compares favorably to that reported in the literature (84–96%).
