Simultaneous disorders of the pharynx and esophagus are so frequent that the complete swallowing chain should be examined in all patients with dysphagia. Data are presented to support the concept that such simultaneous disorders represent related phenomena; the mechanism involves changes in cricopharyngeal function seen radiographically as cricopharyngeal prominence. If neurologic disease has been excluded, cricopharyngeal prominence may be the clue to esophageal disease. When cricopharyngeal prominence is found during dynamic imaging of the pharynx, intensive examination of the esophagus and a search for signs of compensation or decompensation in the pharynx should be undertaken.
咽和食管同时出现病变的情况非常常见，因此对于所有吞咽困难的患者都应检查完整的吞咽环节。现有数据支持这样一种观点，即这些同时出现的病变代表相关现象；其机制涉及环咽肌功能的改变，在影像学上表现为环咽肌隆起。如果已排除神经系统疾病，环咽肌隆起可能是食管疾病的线索。当在咽部动态成像过程中发现环咽肌隆起时，应加强对食管的检查，并寻找咽部代偿或失代偿的迹象。
