Establishment of treatment strategy for dysphagia based on objective evaluation of swallowing function

作为吞咽困难的客观定量评价指标，电视透视喉头抬高延迟时间(LEDT)和咽部通过时间(PTT)显著延长，并与吞咽困难的严重程度呈正相关。我们提出的吞咽视频内窥镜检查评分系统，有助于评估吞咽困难的特点和口腔营养的可行性。在治疗中，辣椒素通过温度感觉刺激作用改善了LEDT和PTT。对于声门关闭反射和吞咽反射启动仍严重受扰于3-4个月强化保守治疗的患者，应考虑手术干预。

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.
