Decannulation in Revision Pediatric Laryngotracheal Reconstruction.

Abstract

To evaluate how patient characteristics and surgical techniques influence the rate of and time to decannulation after pediatric revision laryngotracheal reconstruction. The study was a retrospective cohort investigation of children with a history of laryngotracheal stenosis treated between 2008 and 2021 with revision open airway surgery. The primary outcome evaluated was decannulation. The secondary outcome analyzed was time to decannulation. Thirty-nine children were included in the study with median age 49 months; 61.5% were male. Children undergoing single stage revision surgery were far more likely to be decannulated (OR 6.25, 95% CI 1.33-45.97, p = 0.0343). Rolling logistic regression of the probability of decannulation stratified by time between open surgeries demonstrated significantly decreased chance of decannulation with reoperation within 6 months. Children managed with anterior/posterior grafting compared with a single graft were observed to have an increased time to decannulation, (HR 0.365, 95% CI 0.148-0.899, p = 0.005, Log-Rank). We observe that in the case of revision pediatric open airway surgery, chance of decannulation is improved when surgery is performed in a single stage as well as 6 months after the most recent procedure. Patients and families should be counseled that complex stenosis requiring double stage procedures or anterior/posterior grafting is associated with a decreased probability of decannulation and increased postoperative time with a tracheostomy, respectively. 4 Laryngoscope, 134:1926-1932, 2024.
