Abstrakt: Introduction: Difficult tracheal intubation is associated with serious morbidity and mortality and cannot be always predicted based on preoperative airway assessment using conventional clinical predictors. Ultrasonographic airway assessment could be a useful adjunct, but at present, there are no well-defined sonographic criteria that can predict the possibility of encountering a difficult airway. Aims: To.assess the usefulness.of USG in predicting difficult laryngoscopy. Materials and methods:. It is a descriptive observational study done conducted in a total of 80 patients were enrolled for. the study and informed. consent was obtained from all the patients. ASA grade I / II, Age 18-60.years of either sex, Patients.undergoing elective. surgery under.general anaesthesia. Results: The incidence of difficult intubation was 23%. We found that Skin to Epiglottis Distance at level of Thyrohyoid membrane on USG (USG-SET) > 1.67 cm had a sensitivity of 78.9% and specificity of 90.2% in predicting a CL Grade of 3 or 4, which was higher than that of physical parameters like MMPC, Wilson's score, Neck circumference or BMI. Conclusions: USG can be used to predict difficult airway preoperatively by measuring soft tissue thickness at neck and Skin to epiglottis distance at the level of Thyrohyoid membrane on USG is a potential predictor of difficult intubation.
