This study aims to construct a computer-aided diagnosis model for middle ear cholesteatoma based on integrated convolutional neural networks (CNNs) to improve diagnostic accuracy and efficiency. <b>Methods:</b> Firstly, Data were collected from patients who visited the Department of Otorhinolaryngology Head and Neck Surgery at the First People's Hospital of Yinchuan between January 2020 and December 2021. 8 000 temporal bone CT images were collected, including 5 000 images diagnosed pathologically as middle ear cholesteatoma and 3 000 normal images. A five-fold cross-validation method was used to divide the dataset into training and testing sets. Next, a transfer learning approach was used to initialize model parameters, and the AlexNet, GoogleNet, and ResNet networks were pre-trained to extract deep features from the images. Then, the Softmax classification algorithm was applied to classify the features, resulting in three independent classifiers. These classifiers were combined using an ensemble learning method with a weighted voting approach to obtain the final diagnostic results. Finally, the model was evaluated by comparing the ensemble classifier with individual classifiers to assess its accuracy, precision, sensitivity, specificity, and diagnostic time, and a comparison with low-mid-and high-experience physician groups was conducted to comprehensively evaluate the model's diagnostic performance. <b>Results:</b> The experimental results showed that the model achieved an accuracy of 88.8%(178/200), precision of 92.9%,(112/120) sensitivity of 89.8%(108/120), and specificity of 88.1%(70/80). The average diagnostic time for individual patient temporal bone CT images was reduced to 2-3 seconds.

All of them were treated with triple semicircular canal occlusion under continuous irrigating mode of endoscopic ear surgery (CIM-EES) in RenMin Hospital of WuHan University. The surgical procedure involved the following key steps: the bony walls of the three semicircular canals near the ampullae were gradually thinned to expose the blue line. The endoscope was positioned as close as possible to the operating area to obtain a clear, magnified view. A micro hook needle was used to create a window on the bony semicircular canals. The hook needle progressively removed the bony material while preserving the membranous canals, which were clearly visible during the procedure. The bone dust was removed out of the surgical area by the continuous exchanged insuline without the help of suction that can avoid the damage of the membranous semicircular canals caused by aspiration and the open bony canals were precisely filled with bone wax and covered with bone powder to ensure complete occlusion of the three semicircular canals. Postoperative follow-up included regular assessments of vertigo control and hearing preservation. <b>Results:</b> All the 3 patients obtained complete hearing preservation at 6 months after surgery, and the hearing preservation rate was 100%.
