Background and Objectives Airway reconstruction surgery in children is still challenging,especially in cases of combined subglottic and posterior glottic stenosis (PGS). The aimof this study was to review the underlying reasons of failure in open airway reconstructionsurgeries performed for children with combined subglottic and PGS.
Subjects and Method We reviewed medical records of seven children who received morethan two open airway reconstruction surgeries to finally achieve and maintain decannulationstatus for more than one year. Twenty-two reconstructive surgeries were performed and theyconsisted of 19 laryngotracheal reconstruction (LTR), 2 cricotracheal resection with end-toendanastomosis (CTR) and one extended CTR. For each patient, the following potentialcauses of failure were evaluated; preoperative evaluation (PE), type of reconstruction (TR),single vs. double staging (SDS), type of stent (TS), and perioperative optimization (PO).
Results The median age of patients at the time of surgery was 32 months (range, 4-64months). Successful decannulation was achieved after the median open surgery of three (range,2-5 times for each patient). Recognized causes of failure were as follows: 8 insufficient PE,10 inadequate TR, 3 improper SDS, 8 ill-chosen TS, and 2 inappropriate PO.
Conclusion PE of dynamic airway is important, especially vocal fold mobility and tracheomalacia.
Types of reconstruction should be carefully decided after full consideration of potentialcauses of failure, and adequate laryngotracheal stent is essential.
