Difficult airway remains a potential problem for practicing anaesthesiologists. Various studies have been conducted to assess the airway and hence predict the difficulty in intubation. However, modified mallampatti test is one of the important tests to predict a difficult airway. Modified mallampatti test alone has low sensitivity and specificity. Preoperative assessment of the airway using a combination of simple tests will increase the sensitivity and specificity of prediction of difficult airway than using a single parameter alone. Hence this study was undertaken to assess the validity of combination of parameters in preoperative prediction of difficult endotracheal intubation in adults posted for elective surgeries under GA.
