Abstract
Background: The upper lip bite test (ULBT) introduced in 2003 is a simple method for predicting difficult intubations. According to this test, the higher a patient can bite the upper lip with the lower incisors, the lower the risk of difficult intubation. Given the necessity for evaluation and re-evaluation of a newer predictive method, this study was conducted to compare the ULBT with another method for difficult airway prediction, the measurement of thyromental distance (TMD).
Aim: To compare upper lip bite test with the measurement of thyromental distance for the prediction of difficult intubation.
Objectives: To compare sensitivity, specificity, positive predictive value and negative predictive value of upper lip bite test (ULBT) with the measurement of thyromental distance (TMD) for the prediction of difficult intubation.
