Key Points

This research aims to evaluate the accuracy of endotracheal tube selection methods in pediatric nasal intubation.
Retrospective study of 677 pediatric patients aged 2–10 years
Patients stratified by body-mass index (BMI)
Comparison of actual ETT measurements with predictions from modified Motoyama formula
Statistical comparisons and Bland–Altman analyses conducted
Median ETT diameter matched the estimated value from the formula (4.5 mm vs. 4.25 mm; p=0.054)
Modified Motoyama formula overestimated ETT insertion depth (actual: 15.5 cm, predicted: 16.5 cm)
Median difference in depth prediction was –1.5 cm (IQR: –3.0 to 0.0; p<0.05)
