Applications of Machine Learning in Meniere's Disease Assessment Based on Pure‐Tone Audiometry

Abstract Objective To apply machine learning models based on air conduction thresholds of pure‐tone audiometry for automatic diagnosis of Meniere's disease (MD) and prediction of endolymphatic hydrops (EH). Study Design Retrospective study. Setting Tertiary medical center. Methods Gadolinium‐enhanced magnetic resonance imaging sequences and pure‐tone audiometry data were collected. Subsequently, basic and multiple analytical features were engineered based on the air conduction thresholds of pure‐tone audiometry. Later, 5 classical machine learning models were trained to diagnose MD using the engineered features. The models demonstrating excellent performance were also selected to predict EH. The model's effectiveness in MD diagnosis was compared with experienced otolaryngologists. Results First, the winning light gradient boosting (LGB) machine learning model trained by multiple features demonstrates a remarkable performance on the diagnosis of MD, achieving an accuracy rate of 87%, sensitivity of 83%, specificity of 90%, and a robust area under the receiver operating characteristic curve of 0.95, which compares favorably with experienced clinicians. Second, the LGB model, with an accuracy of 78% on EH prediction, outperformed the other 3 machine learning models. Finally, a feature importance analysis reveals a pivotal role of the specific pure‐tone audiometry features that are essential for both MD diagnosis and EH prediction. Highlighted features include standard deviation and mean of the whole‐frequency hearing, the peak of the audiogram, and hearing at low frequencies, notably at 250 Hz. Conclusion An efficient machine learning model based on pure‐tone audiometry features was produced to diagnose MD, which also showed the potential to predict the subtypes of EH. The innovative approach demonstrated a game‐changing strategy for MD screening and promising cost‐effective benefits for the health care enterprise.
