Abstract:

The appropriate airway management is the important point during the anesthesia. For it dose, taking history, physical examination (head and neck, mandible, mouth opening, neck movements …) must be done completely and they are helpful in estimating difficult intubation.

It is necessary to note that one case from every 5000 cases of anesthesia, not only intubation is not possible but also ventilation is impossible.  Direct difficult laryngoscopy happens in 1.5-8.5% of cases and failed intubation occurs in 0.13-0.3% of cases.

Above mentioned points indicated that airway management is important and vital and in the airway difficulties, ventilation auxiliaries such as LMA, combitube, TTJV, and tracheostomy must be used to save patient's life.
