Abstract
- To provide adequate management for upper esophageal dysfunction, one must first understand the physiology of the swallowing. The oropharyngeal swallow involves a rapid, highly coordinated set of neuromuscular actions beginning with lip closure and terminating with opening of the upper esophageal sphincter. The review will describe the pathophysiology and evaluation of the upper esophageal dysfunction in the view point of gastroenterologist.
