Child Clinical Trial
Official title:
Shape and Dimensions of the Upper Airway in Infants Using Computed Tomography Imaging
Cricoid is considered the narrowest part with the shape of airway defined as elliptical with
the subglottis as the narrowest region.
This study using imaging modality (2D CT images) is done to determine any differences in
airway shape between infants and children, and to evaluate the dimensional transition
between the subglottic area and the cricoid ring.
Using imaging modalities (CT, MRI), the funnel-shape of the airway in children has been
questioned and subglottis rather than cricoid is considered the narrowest part with the
shape of airway defined as elliptical with the subglottis as the narrowest region.
This is the first study using imaging modality (2D CT images) to determine the airway shape
and dimensions in neonates and infants. The purpose of this investigation was to determine
any differences in airway shape between infants and children, and to evaluate the
dimensional transition between the subglottic area and the cricoid ring.
