Abstract
Objective: To describe our outcomes after laryngotracheal reconstruction that required posterior costal cartilage grafting focused on decannulation rates and complications.Study Design: Case series with chart review.Subjects and Methods: Charts were reviewed on 58 patients. Operation specific and overall decannulation rates were determined. Complications were reviewed and correlated with technique of graft placement. Available voice outcomes were reviewed.Results: Forty‐eight patients were included. There was no statistically significant correlation between degree of stenosis and rate of decannulation. The overall decannulation rate, regardless of number of surgeries performed, was 96 percent. The relative risk for complications was higher among children who had a sutured versus a sutureless flanged posterior graft (RR = 2.5, P < 0.01). The most common voice anomaly was supraglottic compression.Conclusions: Operation‐specific decannulation rates are not significantly different with increasing disease severity, although the power to detect small differences in this study is low. Sutureless graft placement is associated with a lower complication rate. Supraglottic compression is a common postoperative compensatory vocal behavior and may correlate with disease severity.
