Objective measurement of the subglottic lumen is still lacking in clinical practice. The objective of this study is to evaluate the accuracy of ultrasound and video-bronchoscopy in measuring the subglottic diameter in the pediatric population. This was a blind, prospective clinical study. Ten children undergoing non-life threatening bronchoscopy had their subglottic diameters measured with ultrasound, video-bronchoscopy and endotracheal tube sizing. / Ultrasound and video-bronchoscopy strongly correlated with endotracheal tube sizing in measuring the subglottic diameter. Ultrasound had measurements that were always smaller while video-bronchoscopy had measurements that were slightly larger than endotracheal tube sizing. Video-bronchoscopy may be more accurate than endotracheal tube sizing as the latter method will often underestimate the size of the lumen due to its own limitations. The smaller values obtained by ultrasound suggest it is not ideal to give absolute measurements in this area, but rather a potential tool to detect change of lumen size on follow-up.
