The recent development of microspot micromanipulators for the carbon dioxide laser with 250-μm spot sizes has greatly facilitated the extension of endolaryngeal procedures to children and neonates. It is possible to accurately develop microtrapdoor flaps within the limited exposures in the pediatric subglottis. We have used serial microtrapdoor flaps in the excision of subglottic scar tissue in eight children. In five children, the stenosis was improved with relief of stridor. In three children, the flaps were used as an adjunct to laryngotracheoplasty. The surgical techniques of this procedure are detailed in this report.
