Prediction model is helpful to detect high-risk patients and decrease the risk of un-anticipated difficult airway. Present models are usually based on Mallampati grade and the width of mouth open. However, the prediction accuracy is only about 0.7-0.8 in different populations. Present study is designed to investigate if AI-based prediction model using medical imaging parameters (such as CT and MRI) can increase the accuracy of prediction model.",[51],"Difficult Airway",[53,54,55,56],"difficult airway","AI-based method","medical imaging","prediction model","NOT_YET_RECRUITING","2025-05-20",{"date":60,"type":61},"2025-05-21","ACTUAL",{"date":58,"type":47},{"date":64,"type":47},"2026-05-30",{"name":36,"class":6},1]
