Abstract
Difficult orotracheal intubation (OTI) represents the main cause of anaesthetic morbidity and mortality. A third of all anaesthesia-related deaths are secondary to the inability to maintain a clear airway to guarantee a correct oxygenation, and nearly two-thirds of problems related to the management of the airway occur during anaesthetic induction.
