| Research Abstract |
As an objective and quantitative evaluation of dysphagia, laryngeal elevation delay time (LEDT) and pharyngeal transit time (PTT) by videofluorography significantly extended and correlated with the severity of dysphagia. Scoring system of videoendoscopic examination for swallowing, which we proposed, was beneficial for assessing the features of dysphagia and oral alimentation advisability.
In the treatment, LEDT and PTT improved by capsaicin administration through a temperature sensory stimulation effect. In patients whose glottal closure reflex and swallowing reflex initiation remain disturbed profoundly against 3-4 months' intensive conservative treatments, surgical intervention should be considered.
