Primary Outcome Measures

Name	Time	Method
Determination of sensitivity and specificity values of the 3 methods studied for prediction of difficult intubation at laryngoscopy. The determination of sensitivity and specificity values will be performed by the correlation of airway evaluation in the pre operative consultation according to the methods described by the authors (Wilson, El-Ganzouri and Naguib) and the laryngoscopy classification (Cormack and Lehane classification) at the time of tracheal intubation during anesthesia. The method with higher sensitivity and specificity will be identified.<br><br>

Secondary Outcome Measures

Name	Time	Method
Identify airway evaluation parameters at the pre operative consultation that are associated with difficult intubation at laryngoscopy. Among these parameters we have: the Mallampati classification, the thyromental distance and the interincisor gap. This association will be performed by correlation of the airway parameter evaluated and the laryngoscopy classification (Cormack and Lehane classification) at the time of tracheal intubation during anesthesia.
