The difficult airway is so much a challenge mainly for the un-experienced anesthetist, that it deserves a privileged position in the train- ing program of the residents. Enhanced awareness of the importance of through preoperative airway assessment as routine practice, implementation of airway management algorithms and the introduction of new airway devices are corner stones for a good outcome. The aim of these steps is to diminish the consequences of encountering a difficult airway, that is, to avoid failed intubation and thus brain failure or other complications of hypoxia. The review highlights recent developments in the management of the difficult airway, by no means intending to substitute clinical teaching or comprehensive airway management courses. Difficult intubation can lead to failure to intubate and if associated to difficult mask ventilation or to the worst nightmare- failed mask ventilation – bare the risk of ending up with unwanted outcomes. Therefore, the authors present the predictors of difficult intubation, introducing the Class zero airways, previously described by the same team. A floppy epiglottis might hamper mask ventilation even to this novel described class of patients. New devices and recommended positions for intubation are updated; ways to assess depth of intubation are exposed. The conclusion states how far we are from ideally managing the difficult airways despite novel technology. The opening to learning, exercising, being prepared with alternatives and providing proper equipment while getting experience are the ways to improve our performances and the patients’ final outcome.
