| Research Abstract |
Dysphagia after radiotherapy is major problem for pharyngeal or laryngeal cancer treatment. To evaluate changes of swallowing function after (chemo)radiotherapy, we performed this prospective study by quantitative analysis of video fluorography , laryngeal sensory test, and manometly. Laryngeal sensation was significantly decreased after radiotherapy, but pharyngeal delay or pharyngeal pressure before and after radiotherapy were not significantly deferent.
Our findings show that sensory deterioration of the larynx can result from radiotherapy, but pharyngeal delay is not caused by the deterioration of the larynx.
