Objective:
To estimate the relation of mentohyoid, thyromental and sternomental distances to height, weight and age of children with normal airway.
Methods:
We carried out a prospective, double blind pilot study in 400 children posted for elective surgery to measure mentohyoid, thyromental and sternomental distances pre-operatively followed by intra-op evaluation of intubation using Cormack and Lehane grading.
Results:
On assessing the contribution of age, height and weight to predict mentohyoid, thyromental and sternomental distances in children, the best predictor was found to be height (p=0.001)followed by age (p=0.04)of the patient.
Conclusion:
We have derived simple formulae to predict mentohyoid, thyromental and sternomental distances relevant to airway based on height and age of children.
