The cricopharyngeus muscle (CPM) is a key component of the upper esophageal sphincter (UES). In dysphagia, cricopharyngeus muscle dysfunction (CPD) refers to the muscle's failure to appropriately and completely relax or expand during deglutition. A variety of disease processes may cause CPD, and the resultant clinical manifestation is solid food or solid and liquid dysphagia. Several diagnostic tools are available for dysphagia clinicians to distinguish CPD from other causes of UES dysfunction. For CPD, accurate diagnosis is paramount for the recommendation of appropriate treatment. In appropriately selected patients, intervention at the CPM may yield significant improvement in dysphagia.
