Evaluation of thyromental height test in prediction of difficult airway in obese surgical patients: An observational study.

Background And Aims: Thyromental height test (TMHT) has revealed good potentials for predicting difficult laryngoscopy view (DLV) in non-obese patients, but its accuracy in obese patients is not evident. This study aimed to assess the validity of TMHT as a predictor of DLV in obese surgical patients.

Methods: 105 patients, aged 18-60 years, with body mass index (BMI) >30 kg/m, scheduled for elective surgeries under general anaesthesia with an endotracheal tube inserted using conventional laryngoscope were included.
