dc.description.abstract예상하지 못한 어려운 후두경은 심각한 기도관련 합병증과 연관되어 있다. 본 연구는 후향적으로 수집된 갑상선 수술을 받은 총 14,135명 환자의 경추 측면 X선을 통해 어려운 후두경 (Cormack-Lehane 등급 3-4)를 예측하는 딥러닝 모델을 개발 및 검증하였다. 개발 모델의 성능은 기존의 6개의 딥러닝 모델과 비교하였다. 개발 모델에서 어려운 후두경 예측의 민감도는 95.6%, 특이도 91.2%를 나타냈다. Area Under ROC curve의 경우 개발 모델에서 0.972(0.955~0.988), 기존 모델의 경우 각각 VGG-Net: 0.842, ResNet: 0.841, Xception: 0.863, ResNext: 0.825, DenseNet: 0.889, SENet: 0.875를 나타냈다. 어려운 후두경과 관련된 해부학적 특징을 설명하기 위해 클래스 활성화 맵(Class Activation Map)을 사용하였다. 클래스 활성화 맵에서 설골, 인두 및 경추 주변이 강조되었다. 본 연구를 통해 개발된 딥러닝 모델은 경추 측면 X선 영상을 이용한 어려운 후두경 예측에 높은 성능을 보였다.-
dc.description.abstractAn unanticipated difficult laryngoscopy is associated with serious airway-related complications. We here developed and validated a deep learning-based model that predicts a difficult laryngoscopy (Cormack–Lehane grade 3–4) from a cervical spine lateral X-ray using data from 14,135 patients undergoing thyroid surgery. The performance of our model was compared with six representative deep learning architectures. A class activation map was created to elucidate the anatomical features associated with difficult laryngoscopy. Our model showed 95.6% sensitivity and 91.2% specificity for predicting difficult laryngoscopy. The area under the receiver operating characteristic curve of our model was 0.972 (0.955‒0.988), which was higher than that of other models (VGG-Net: 0.842, ResNet: 0.841, Xception: 0.863, ResNext: 0.825, DenseNet: 0.889, and SENet: 0.875, all P < 0.001). The class activation map demonstrated clear differences around the hyoid bone, pharynx, and cervical spine. The model showed excellent performance for predicting difficult laryngoscopy using a cervical spine lateral X-ray image.-
