We report five patients with Parkinson's disease and dysphagia who were found, by radiological and manometric evaluation, to have evidence of cricopharyngeal dysfunction, which included the presence of a Zenker's diverticulum in two. Cricopharyngeal myotomy was performed in four patients with excellent and sustained improvement in swallowing. We conclude that cricopharyngeal function should be carefully evaluated in patients with Parkinson's disease and dysphagia and that surgical treatment should be considered in appropriate cases.
