To determine the best site for measurement or assessment of the aryepiglottic folds and determine whether evaluation of the lower portion of the folds is useful.
The lateral neck radiographs from 38 children with epiglottitis were retrospectively reviewed and compared with findings in 100 patients with croup and 100 control patients. In all patients, the fold thickness was measured at three levels: at the midpoint (site 1), just behind the epiglottis (site 2), and at the base, just above the false vocal cords (site 3).
Full-thickness measurements obtained at sites 1 and 2 were statistically significant predictors of epiglottitis (sensitivity, 94.74%; specificity, at least 96.50%) in comparison with those obtained in patients with croup and control patients.
The best site for width assessment is the upper half of the folds. Measurement at the base, where the folds overlie the arytenoid cartilage, is not nearly as accurate and should be avoided.
确定测量或评估杓会厌襞的最佳部位，并确定评估襞下部是否有用。
回顾性分析38例会厌炎患儿的颈部侧位X线片，并与100例喉炎患者及100例对照患者的检查结果进行比较。对所有患者，在三个水平测量襞厚度：中点处（部位1）、会厌后方（部位2）以及假声带上方基部（部位3）。
与喉炎患者及对照患者相比，部位1和部位2的全层测量结果是会厌炎的统计学显著预测指标（敏感性为94.74%；特异性至少为96.50%）。
评估襞宽度的最佳部位是襞的上半部分。在襞覆盖杓状软骨的基部进行测量准确性欠佳，应避免使用。
