Predictive value of the Hyodo score in endoscopic evaluation of aspiration during swallowing

The Hyodo scoring method was easy for otolaryngologists to perform and the scores were useful for predicting aspiration with moderate sensitivity and high specificity. Hyodo score > 6, history of aspiration pneumonia, vocal cord paralysis, and PS ≥ 3 were independent predictive factors for aspiration and that a Hyodo score above 6 was the statistically strongest predictor for aspiration.
