Key result
Combining the Modified Mallampati test, thyromental distance, and neck circumference increased the specificity to 82.3% and sensitivity to 100% for predicting difficult intubation compared to individual tests.
Why the study?
Pre-operative tests for predicting difficult intubation have variable positive predictive value, sensitivity, and specificity, risking anesthesia-related mortality and hypoxic brain injury.
Does the combination of Modified Mallampati test, thyromental distance, and neck circumference improve the prediction of difficult intubation in adult patients undergoing elective general surgery?

Does the combination of Modified Mallampati test, thyromental distance, and neck circumference improve the prediction of difficult intubation in adult patients undergoing elective general surgery?
Combining the Modified Mallampati test, thyromental distance, and neck circumference significantly increases the sensitivity and specificity of predicting difficult intubation compared to using these tests individually.
Abid Banavasi (2019) conducted an observational in Difficult airway (n=115). Combination of Modified Mallampati test, neck circumference, and thyromental distance vs. Individual predictive tests was evaluated on Sensitivity and specificity for predicting difficult intubation. Combining the Modified Mallampati test, thyromental distance, and neck circumference increased the specificity to 82.3% and sensitivity to 100% for predicting difficult intubation compared to individual tests.
