Abstract

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. © 1994, SAGE Publications. All rights reserved.
