Conclusion
This study showed that there was a correlation between the degree of
adenoid hypertrophy and the severity of OSAHS in children, with an A/N
ratio ≥0.825 being a good indicator for the diagnosis of OSAHS.
Therefore, nasopharyngeal lateral radiography can be used as a screening
tool for OSAHS in children, especially for primary hospitals where PSG
is not available.
