Laryngopharyngeal sensory deficits and impaired pharyngeal motor function predict aspiration in patients irradiated for nasopharyngeal carcinoma

Abstract

Impaired pharyngeal contraction and food bolus clearance from the hypopharynx during swallowing are more important than laryngopharyngeal sensory deficiency in predicting aspiration in patients who underwent radiotherapy for nasopharyngeal carcinoma.
