<正>Objective: To investigate the effects of anteroposterior cricoid spliting interposition costal grafting for moderate and severe laryngotracheal stenosis in children. Methods: From 1995 to 2005

87 children （aged 1. 2 to 14 years） with moderate and severe glottic and subglottic stenosis were retrospectively studied. They were operated with cricoid spliting laryngotracheal reconstruction in our hospital. All of 87 patients were tracheostomy-dependent before surgery. Results: Eighty-five patients （95%） were successfully decannnulated and got an effective phonation. The follow-up time was more than 5 years. The effect of operation was satisfactory and the growth and development of children was normal. Conclusion: Anteroposterior cricoid split interposition costal cartilage graft is a safe and effective treatment method for moderate and severe glottic and subglottic stenosis in children.
