espanolObjetivo: Determinar la concordancia entre la prediccion de intubacion dificil medida por los indices de Mallampati modificado (Ma), distancia tiromentoniana (DT) y apertura bucal (AB), en pacientes con fractura maxilar y/o mandibular que requirieron manejo del trauma bajo anestesia general con intubacion endotraqueal. Metodologia: estudio descriptivo prospectivo con una muestra 61 pacientes, se diligencio una historia clinica donde se recolecto informacion como: diagnostico, edad, sexo, valores de los indices predictivos, prediccion segun indices, tipo de intubacion, dificultad de intubacion y porcentaje de concordancia. Los datos fueron procesados mediante tabulacion mecanica utilizando una hoja de calculo del programa Excel. Resultados: se evidencio baja concordancia entre la prediccion del indice y la intubacion real lograda, obteniendose 32,8% de prediccion de intubacion dificil, en cuanto a la dificultad en la intubacion durante el procedimiento se encontro que el 83,6% se logro sin dificultad, el 16,4% presento dificultad media y en el 100% de los casos se logro intubar. Conclusion: ninguna de estas clasificaciones e indices predictivos individualmente ofrece una certeza del 100% y presencia de trauma maxilofacial en pacientes adultos intervenidos quirurgicamente con intubacion endotraqueal no limito el compromiso de la via aerea, al igual que en la prediccion de una intubacion dificil. EnglishObjective: To determine the correlation between the prediction of difficult intubation as measured by modified Mallampati index (Ma), thyromental distance (DT) and mouth opening (AB) in patients with a fractured jaw and / or mandibular trauma management requiring anesthesia general endotracheal intubation. Methods: prospective study with a sample 61 patients filled out a medical history is where information was collected as diagnosis, age, sex, values of the predictive index, prediction based indices, type of intubation, difficult intubation and percentage of agreement. The data were processed by machine tabulation using a spreadsheet program Excel. Results: We showed poor agreement between predicted real rate and intubation achieved, yielding 32.8% for predicting difficult intubation, as to the difficulty of intubation during the procedure found that 83.6% was achieved without difficulty, 16.4% had moderate difficulty and 100% of cases intubation was achieved. Conclusion: None of these classifications and predictive indexes individually offers a 100% certainty and presence of maxillofacial trauma in adult patients undergoing surgery with endotracheal intubation did not limit the commitment of the air, as in predicting difficult intubation.
