A total of 21 CMO indicators, including demographic, clinical, laboratory, and imaging data, were collected. In the training set, univariate analysis, Least Absolute Shrinkage and Selection Operator (LASSO) regression, and multivariate logistic regression were used to identify core predictive variables. Four machine learning models\u2014Random Forest, Logistic Regression, K-Nearest Neighbors, and Gradient Boosting Machine\u2014were constructed using these variables. Model performance was assessed using the area under the curve (AUC), calibration curves, and decision curve analysis (DCA). Interpretability was analyzed with SHapley Additive exPlanations (SHAP).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Multivariate analysis identified a history of diabetes, previous ear surgery, otorrhea, middle ear mucosal status, cholesteatoma presence, Eustachian tube function score, and preoperative C-reactive protein level as independent risk factors. Among the constructed models, the Random Forest model demonstrated superior overall performance, and the model was 0.885 in the training set and 0.853 in the validation set. The model also showed good calibration. DCA indicated significant clinical net benefit across a wide threshold probability range. SHAP analysis confirmed that a history of previous ear surgery and cholesteatoma presence were the most influential predictors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A machine learning-based prediction model for complications after COM surgery was developed and validated.
