However, traditional supervised deep learning models for their detection are constrained by class\u2010specific training, reliance on large\u2010scale labelled datasets, and unpredictable generalisability. This study aims to achieve intelligent detection of complex and variable maxillary sinus abnormalities via self\u2010supervised learning.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>A maxillary sinus foundation model (MSFound) was developed using self\u2010supervised learning on 30\u2009794 unlabeled maxillary sinus images. Clinical validation of reconstructed images was conducted to verify the pre\u2010training effect. MSFound was then fine\u2010tuned using labelled images at different proportions for downstream tasks, including mucosal thickening, polypoid lesions, and the palatonasal recess. Model performance was evaluated on multicentre datasets using AUROC, AUPR, and accuracy, and was compared with different training strategies. Clinical applicability was also prospectively evaluated in multicentre settings.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>MSFound successfully reconstructed the main anatomical structures of the maxillary sinus, and clinical validation confirmed the effectiveness of pre\u2010training. During the fine\u2010tuning process, MSFound achieved the highest performance with the least amount of labelled data compared to control groups across all tasks. The model consistently achieved the highest AUROC, AUPR, accuracy, and F1\u2010score on multicentre test sets. Visualisation analyses showed that MSFound focused on key image regions when predicting correctly. Prospective clinical applicability results further demonstrated the real\u2010world effectiveness of MSFound.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>MSFound enables robust detection of multiple maxillary sinus abnormalities with minimal labelled data, demonstrating strong generalisability and real\u2010world clinical value.
