About

Anesthesia is increasingly safe. Major complications of airway management are no more common but still the most life-threatening condition amongst anesthesia practice and even medicine. Thyromental height test (TMHT) is an objective measure of the height between the anterior borders of the mentum and thyroid cartilage, measured while the patient is lying supine with the mouth closed. This study was designed to assess the validity of the TMHT as a single objective predictor for difficult laryngoscopy and to be compared to other objective measures.
