    A CT-derived model was developed to predict endotracheal tube dimensions for infants under one year, enhancing size selection accuracy.

  • 2

    Age and preterm birth were identified as independent factors influencing the shortest cricoid cartilage diameter in infants.

  • 3

    The prediction formulas for cricoid cartilage diameter differ between full-term and preterm infants, indicating size variations.

  • 4

    Age was the only significant factor affecting the distance from the cricoid cartilage to the carina in infants.

  • 5

    The study highlights the need for broader validation of the model due to limitations like small sample size and lack of external validation.
