Median ± 25^th and 75^th percentile laryngeal resistance at all airflows in control larynges and post placement of the bilateral arytenoid abductor with the epiglottis open. The number of larynges that were tested at each flow rate are included. At high flow rates during control testing, the smallest larynx collapsed
