In adult patients, various predictive tests for difficult airway are used. The modified Mallampati test (MMT) is a simple airway assessment tool to predict difficult intubation from the anatomy of oropharynx. Other bedside tests like Thyromental distance (TMD), Ratio of height to thyromental distance (RHTMD), Mandible Protrusion Test (MPT), Modified measurement of Sterno-mental distance are routinely used to evaluate difficult intubation in adults. The use of various preoperative airway assessment parameters for predicting difficult intubation in adults has been established in the literature. However, unlike adults, there are no defined parameters in the paediatric population that can help predict and recognize paediatric patients who are at risk of difficult intubation. These tests have different sensitivity and specificity in predicting difficult airway. It is not clear, which method is better than others for prediction of difficult laryngoscopy.

 In view of above situation, we are conducting a study to compare the predictive value of various tests for predicting difficult laryngoscopy in children aged between 6 – 12 years who are posted for elective surgery.
