The cricopharyngeus is a narrow band of muscle strategically placed between the pharynx and esophagus. Its normal function is vital to the efficient transfer of foodstuffs to the esophagus. Cine- and videoradiography are the major methods of studying the pharyngo-esophageal segment. More recently, refinements in manometric methods have complemented radiology, and have enabled us to achieve a better understanding of cricopharyngeal function in health and disease. Such an understanding of the physical forces necessary for normal bolus transfer, and the recognition of abnormal patterns of pharyngeal and cricopharyngeal motility, will hopefully lead us to a more rational approach to therapy in patients with pharyngeal dysphagia.
环咽肌是位于咽和食管之间的一条狭窄肌肉带。其正常功能对于食物有效输送至食管至关重要。电影和视频放射成像术是研究咽食管段的主要方法。最近，测压方法的改进补充了放射学，使我们能够更好地了解环咽肌在健康和疾病状态下的功能。对正常食团输送所需物理力量的这种理解，以及对咽和环咽肌运动异常模式的认识，有望引导我们以更合理的方法治疗咽吞咽困难患者。
