Final answer:
The Mallampati score, thyromental distance, and interincisor gap are the most sensitive indicators of difficult intubation.
Step-by-step explanation:
The most sensitive indicators of difficult intubation include the Mallampati score, thyromental distance, and interincisor gap. These indicators help assess the anatomical characteristics that may make intubation challenging. The Mallampati score evaluates the visibility of the patient's uvula and tonsils, while thyromental distance measures the distance between the thyroid notch and the chin. The interincisor gap assesses the space between the upper and lower incisors.
