It was found that the pharyngoesophageal sphincter mechanism remains intact in the case of complete paralysis of the hypopharynx. When there are severe symptoms of dysphagia, myotomy of the pharyngoesophageal sphincter is to be considered on the basis of these diagnostic findings. This procedure can lead to substantial improvement of the symptoms. Sphincterotomy yielded very favorable results in five out of nine patients, two of whom are discussed in some detail by way of illustration.<\/jats:p>","DOI":"10.1177\/000348947908800503","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:29:51Z","timestamp":1412346591000},"page":"596-602","source":"Crossref","is-referenced-by-count":17,"title":["Cricopharyngeal Myotomy in Pharyngeal Paralysis"],"prefix":"10.1177","volume":"88","author":[{"given":"Jos J.M.","family":"Van Overbeek","sequence":"first","affiliation":[{"name":"Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hans C.","family":"Betlem","sequence":"additional","affiliation":[{"name":"Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1979,9]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"Valsalva AM: De Aure Humana Tractates.
