To demonstrate the accuracy of the Naguib formula and the Arne index in the diagnosis of difficult tracheal intubation in general anesthesia in adult patients. Material and methods: A retrospective analytical study of diagnostic tests was performed. The sample was by convenience of all patients who underwent surgery at the Regional Hospital of Loreto under general anesthesia between January 2012 to December 2022, ASA I-III patients and who registered in the anesthesia sheet the postoperative diagnosis of Difficult Tracheal Intubation (ITD). From the data obtained we proceeded to form a group of cases (patients with difficult airway recorded in the medical record) and a control group with 82 patients each. Results: The average age in the case group was 54,1 and 53,9 for the controls, in relation to the sex of the participants in the case group there was the same proportion of males and females (41/41), unlike the control group where the proportion was (31/51), for variables such as age, sex, weight and BMI no significant statistical difference was found. For the predictors commonly used at the time of evaluating a difficult airway (DAV): Thyromental distance (TTM), Mallampati and Interincisive distance (IID), OR results were obtained of 5,71; 0,01 and 2,35 respectively, both the OR of the TTM and IID would have greater association at the time of predicting a DAV. The accuracy of the Naguib formula was 82%, sensitivity of 88% (95% CI), specificity of 77%, PPV of 79% and NPV of 86% compared to the Arne model index which had an accuracy of 75%, sensitivity of 91%, specificity of 59%, VPP of 69% and VPN of 87% , and the calculated value of the ROC curve for the Naguib model was 0,890 compared to 0,842 for the Arne index. Conclusion: Naguib's Formula can be used as a routine screening test for preoperative predictions of difficult tracheal intubations as it has high accuracy, specificity, positive predictive value and good sensitivity
