Abstract
Objective:To assess the indications and outcomes of laryngotracheal reconstruction (LTR) using the sternohyoid myocutaneous flap (SMF) in pediatric patients with laryngotracheal stenosis. Method:Twenty patients (15 males, 5 females; mean age, 9 years old, range 3 to 14) with laryngotracheal stenosis who underwent SMF procedures at Tangdu Hospital between August 1991 and October 2014 were analyzed. Stenosis was classified according to the Myer-Cotton grading system. Four patients were grade Ⅱ, ten were grade Ⅲ, and six were grade Ⅳ. The mean length of stenosis was 1.8 cm (rang, 0.3-4.0 cm). Three patients had concomitant unilateral vocal paralysis and 2 had bilateral vocal paralysis. Result:Fourteen of 20 patients (70%) were decannulated. The prevalence of decannulation for grade Ⅱ, Ⅲ, and Ⅳ was 100%, 70%, and 50%, respectively. There were no severe complications. Conclusion:The SMF is a relatively simple and reliable method for LTR but should be used cautiously if employed in severe cases such as grade Ⅳ with long-segment stenosis.
