We measured interarytenoid notch height (IANH) in 20 young children who required direct laryngoscopy under general anesthesia. By means of a specifically designed instrument, we found that the average IANH approximated 3 mm. Laryngeal incompetence on swallowing or in the presence of gastroesophageal reflux is associated with a low IANH (p < .0001). Therefore, IANH may be a measure of relative laryngeal incompetence.
我们对20名需要在全身麻醉下进行直接喉镜检查的幼儿测量了杓间切迹高度（IANH）。通过一种专门设计的仪器，我们发现IANH的平均值约为3毫米。吞咽时或存在胃食管反流时的喉部功能不全与低IANH相关（p < .0001）。因此，IANH可能是相对喉部功能不全的一种度量。
