TABLE 2 MALACIA SCORING SYSTEM Arytenoid score (AS)*   0 points No discernible collapse into glottis with inspiration   1 point Subtle collapse of arytenoids into glottis   2 points Collapse of arytenoids into glottis, 25 to 50% of vocal cords ob-   scured   3 points Collapse of arytenoids into glottis, about 75% of vocal cords ob-   scured   4 points Collapse of arytenoids into glottis, 100% of vocal cords obscured Epiglottis score (ES)   0 points Normal epiglottis, no folding during inspiration   1 point Slight length-wise folding of epiglottis   2 points Moderate fold of epiglottis without contact between lateral edges   3 points Intermittent contact of lateral edges of epiglottis   4 points Continuous contact and even overlap of lateral edges of epiglottis * If the two arytenoids varied in score, the mean score was used. The sum of the arytenoid and epiglottis scores is the laryngomalacia score (LS). The difference between prelidocaine LS and postlidocaine LS is the LS.
