The pharyngeal airway is a vital component of the respiratory system's function. Assessment of the pharyngeal airway dimensions in different skeletal types is essential in the orthodontic treatment of growing patients.
A recent study compared the upper pharyngeal airway dimensions of 7–14-year-old children with different skeletal types.
It grouped 361 lateral cephalometric radiographs based on their skeletal patterns determined by the ANB angle as:
And categorized radiographs into four groups:
The study utilized cephalometric measurements like SNA, SNB, ANB, Ad1-PNS, Ad2-PNS, McUP, and McLP and used ANOVA to compare the group results.
The results from the study were as follows-
Thus, the upper pharyngeal airway dimensions showed an age-dependent increase in 7–14-year-old children, particularly in skeletal types II and III. Hence, clinicians can use upper pharyngeal airway dimensions to differentiate the different skeletal classes in clinical settings.
