AbstractAirway management is most important job of anaesthesiologists. Difficult airway is assessed mainly comparing different parameters of airway assessment. In this study we mainly compare Upper Lip Bite test (ULBT) and Modified Mallampati Test (MMT) for prediction of difficult intubation. We have taken 100 patients’ database from RIMS Ranchi hospital, study have been done in all patients undergoing general anaesthesia. After database is designed, data are processed through SPSS and Excel software analysis. In this case we have gone through 100 patients and subsequently after grading ULBT and MMT, taking Cormack Lehane Grading as standard one. Comparison done on the basis of sensitivity, specificity, positive predictive value, negative predictive value, accuracy. It was observed from the study that MMT is better predictor of difficult intubation than ULBT. Both are predictors of good predictors of easy intubation rather than difficult intubation.
