    Introduction: One of the main complications is the difficult airway in patients undergoing general anesthesia, so it is important to be prepared for management using predictors. Objective: To determine the predictive value of the Wilson and LEMON scale for the prediction of difficult airway and its relationship with the Cormack scale at the José Carrasco Arteaga Hospital in the city of Cuenca in the period January - December 2018. Methods: An observational, descriptive evaluation study of diagnostic tests was carried out during 2018. The population consisted of patients who underwent surgery under general anesthesia and intubated by laryngoscopy. The sample was 350 patients, the presence of predictors of the difficult area was determined using the Lemon and Wilson scales and their results were compared with the Cormack scale. The data were analyzed with the SPSS 22.0 free version system. Results The prevalence of difficult airway according to the Cormack scale was 13.14%, according to the Lemon scale of 8.6% and Wilson 5.1%. sensitivity 47.83% 26.09% specificity 97.37% 98.03% Validity index 90.86% 88% Positive predictive value 73.33% 66.67% Negative predictive value 92.50% 89.76% Kappa index 53% 32.5% Youden index 0.45 0.24 Probability ratio 18.17 13.22 Reason for likelihood 0.54 0.75 Conclusions due to the low prevalence of the scales comparing Cormack's, it is concluded that they are not useful for predicting difficult airways, but for easy airways.
