Jain A, et al. - Given that serious complications can develop due to malpositioning of the endotracheal tube within the airway, therefore, researchers performed this study with Indian pediatric population, to determine if the upper incisor‐manubriosternal joint length in the extended head position can serve as a predictor of airway length to guide the depth of insertion of endotracheal tube in children as well as to assess the correlation of upper incisor‐manubriosternal joint length with the upper incisor‐carina length in the neutral head position. They found a positive correlation of upper incisor‐carina length with the patient's upper incisor‐manubriosternal joint length and the patient's standing height, while the degree of maximum head extension was shown to have no significant bearing on this association. Experts concluded that upper incisor‐manubriosternal joint length can predict airway length and the depth of insertion of endotracheal tube in pediatric population.
