Swallowing is a complex physiologic process in which the upper esophageal sphincter plays an important role. Dysfunction of the cricopharyngeal muscle, the main component of the upper esophageal sphincter, can lead to dysphagia, weight loss, and aspiration pneumonia. Several treatment options directed at the cricopharyngeal muscle including dilation, botulinum toxin injections, and transcervical or endoscopic myotomy can improve swallowing function. This chapter will discuss the various treatment options for dysfunction of the cricopharyngeal muscle.
