Airway  management is the fundamental  responsibility of every anaesthesiologist.Difficult  intubation is a major cause of morbidity and mortality related to Anesthesia.This study is designed to predict difficult intubation in patients, by comparing Modified Mallampati test, Thyromental distance and their combination. Study was conducted on 300 patients posted for elective surgery according to the inclusion and exclusion criteria. Mallampati grade and thyromental distance noted and Cormack lehane grading seen on intubation.It was observed that there was a statistical significance seen when using Mallampati as an assessment of airway, proving that it can be used as significant measure in assessment of easy intubation ( p value 0.002) and similar with thyromental distance ( p value <0.001) . No significant co relation ( kappa0.108) between mallampati and Cormack lehane but fair co relation ( kappa 0.232) between thyomental and Cormack & lehane.This study has shown that the combination of Modified Mallampati and thyromental distance is better and adds some incremental diagnostic value when compared to value of each predictor used alone.
