Thyromental Height Test (TMHT) as a Predictor of Difficult Airway in Obese Patients

Cairo University105 enrolled

Overview

Difficult airway management is a major concern for anesthetists and contributes to perioperative morbidity and mortality. The incidence of difficult intubation in the obese population with a BMI of greater than 30 has been reported to be 15.8%. Thyromental height test (TMHT) is a new bedside test for difficult airway, it is a measure of the height between the anterior borders of the mentum and thyroid cartilage. TMHT can act as a surrogate for amount of mandibular protrusion; dimensions of submandibular space; and anterior position of the larynx. It appears promising as a single anatomical measure to predict the risk of difficult laryngoscopy.
