Two scores were developed from a study conducted in 2019. The first score, to predict a difficult laryngoscopy, uses two parameters: the modified MALLAMPATI class (MMS) and the STM. A score strictly greater than 2 is predictive of a difficult laryngoscopy. The second score, to predict difficult ventilation, uses four parameters: BMI, NC, TT in coronal plane, and SHB. A score strictly greater than 20 is predictive of difficult ventilation. A well-experienced anesthesiologist performed a direct laryngoscopy and graded it as Cormack-Lehane's grading.\n\nDifficulty in intubation and\u002For mask ventilation was managed according to the 2017 SFAR guidelines.",[24,25,26,27],"Airway Complication of Anesthesia","Ultrasound","Laryngoscopy","Difficult Airways","NOT_YET_RECRUITING","2024-07-16",{"date":31,"type":32},"2024-07-22","ACTUAL",{"date":34,"type":20},"2024-08-15",{"date":36,"type":20},"2024-12-30",{"name":38,"class":39},"Mongi Slim Hospital","OTHER"]
