Since the most susceptible portion for airway damage is unyielding portion, the findings suggest that, functionally, the narrowest portion of the pediatric larynx is located in the subcricoid region.

Revisiting the Morphometry of Cricoid Cartilage and Vocal Folds
The transverse diameter of the rima glottidis was the narrowest part of the laryngeal passage and the physicians should be aware of this part ofThe larynx besides the cricoid cartilage during endotracheal tube administrations.

Comparison of cricoid and subcricoid transverse diameter of trachea to determine correct size of endotracheal tube in pediatric population: An observational study
US-guided cricoid diameter can act as a reliable method to ascertain the proper size of ET tube, closely followed by US-guided subcricoid diameter over the traditional age-based formula.

Ultrasonography measurement of glottic transverse diameter and subglottic diameter to predict endotracheal tube size in children: a prospective cohort study
We aimed to determine the correlation between mid-glottic transverse diameter/subglottic diameter and outer diameter of endotracheal tube (ETT) by ultrasonography in children. Ninety-five patients...

Analysis of Pediatric Acute Upper Airway Pathology During Local Wildfires and Increased PM 2.5 Burden
As wildfires worldwide increase in severity and frequency, fine particulate matter (PM 2.5), generated as a component of wildfire smoke, increasingly impacts air quality and the clinical effects of PM 2.5 on the pediatric upper airway are poorly understood and warrant investigation.

Pediatric Laryngeal Dimensions: An Age-Based Analysis
In this study of infants and children, the glottis rather than cricoid was the narrowest portion of the pediatric airway.

Developmental Changes of Laryngeal Dimensions in Unparalyzed, Sedated Children
In sedated, unparalyzed children, the narrowest portions of the larynx are the glottic opening and the immediate sub–vocal cord level, and there is no change in the relationships of laryngeal dimensions relative to cricoid dimensions throughout childhood.

The shape of the pediatric larynx: cylindrical or funnel shaped?
In this issue of Anesthesia & Analgesia, Dalal et al. published a study on the laryngeal dimensions with magnetic resonance imaging scans in 99 infants and children, neonates to 14-yr-old, spontaneously breathing under deep sedation with propofol and found that the shape of the pediatric larynx was "conical in the transverse dimension with the apex of the cone at the level of the vocal cord and cylindrical in the AP dimension

Determination of Endotracheal Tube Size in a Perinatal Population: An Anatomical and Experimental Study
The elasticity of laryngeal structures in premature babies is identified, allowing intubation with tube sizes greater than predicted by anatomical measurements with an increasing injury risk located in the posterior part of the glottic plane.

The rate of growth of the cricoid cartilage
Recent interest in the condition of subglottic stenosis and post intubational stenosis of the lower respiratory tract led to a search through the literature to determine the rate at which the larynx and trachea enlarged but no work in this field was found.

Prediction of Pediatric Endotracheal Tube Size by Ultrasonography
Measuring subglottic upper airway diameter with ultrasonography facilitates the selection of appropriately sized ETTs in pediatric patients and better predicted optimal outer ETT diameter than standard age- and height-based formulas.

Ultrasonographic Estimation of Endotracheal Tube Size in Paediatric Patients and its Comparison with Physical Indices Based Formulae: A Prospective Study.
Ulasonographic estimation of subglottic diameter is useful for optimal paediatric ETT size selection and is effective in estimating the appropriate sized ETT both for cuffed and uncuffed tubes.

Tracheal cross-sectional area in children: CT determination.
A computer method that calculates tracheal cross-sectional area by compensating for partial volume averaging was developed and validated in a study with phantoms and CT-derived cross sections were correlated with age, height, weight, and body-surface area.

ORIGINAL REPORT
In this study, the degree of dynamic collapse correlated well with bronchoscopic results, and multidetector CT with inspiratory–expiratory imaging is a promising method in the evaluation of patients with dynamic airway collapse.
