Open vs. endoscopic cricopharyngeal myotomy; Is there a difference?

The upper esophageal sphincter (UES) is composed largely of the cricopharyngeus muscle (CP) and acts as the gatekeeper to the esophagus. There are multiple methods of treating UES dysfunction, but myotomy has been shown to be the most definitive means. We aim to evaluate the difference between open and endoscopic CP myotomy (CPM).
