咽功能障碍主要与延髓和假延髓血管病变有关。其他原因有颅底肿瘤、脊髓灰质炎、横纹肌病变如肌强直性营养不良和重症肌无力。仅管如此,大多数咽功能障碍的病因尚不清楚。有人认为胃食管返流(GER)可以导致咽功能障碍和吞咽困难。为此作者研究了84例吞咽困难、临床疑有食管病变的病人,其中男37例,女47例,年龄30～75(平均57)岁。所有病人均进行了咽和食管的X线检查。咽的X线检查采用前后位及侧位X线电影摄影。咽功能的分析包括:会厌运动,喉前庭闭合,声门裂消失,咽缩肌收缩,环咽肌松弛以及下咽部憩室和蹼的存在等方面。食管的X线检查首先采用立位或坐位造影以确定其形态,然后取俯卧头 Pharyngeal dysfunction is mainly associated with medulla oblongata and pseudobulbar vascular lesions. Other causes are skull base tumors, poliomyelitis, rhabdomyosarcoma such as myotonic dystrophy and myasthenia gravis. However, the etiology of most pharyngeal dysfunction is unclear. Some people think that gastroesophageal reflux (GER) can lead to pharyngeal dysfunction and dysphagia. To this end, the authors studied 84 patients with dysphagia and suspected esophageal disease, including 37 males and 47 females, aged from 30 to 75 (mean 57 years). All patients underwent pharyngeal and esophageal X-ray examination. Pharyngeal X-ray examination using anteroposterior and lateral X-ray film photography. Analysis of pharyngeal function include: epiglottis movement, laryngeal vestibular closure, disappearance of gliomas, contraction of pharyngeal constrictor, cricopharyngeal muscle relaxation and hypopharyngeal diverticulum and web presence. Esophageal X-ray examination using the first position or sitting radiography to determine its shape, and then take the prone position
