A brief outline of the causes and symptoms of hypopharyngeal paresis is followed by a discussion of the diagnostic possibilities of manometry and cineradiography. 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.
本文首先简要概述下咽麻痹的病因和症状，随后讨论测压法和荧光透视检查法的诊断可能性。研究发现，在下咽完全麻痹的情况下，咽食管括约肌机制仍保持完整。当出现严重吞咽困难症状时，可根据这些诊断结果考虑对咽食管括约肌进行肌切开术。此手术可使症状得到显著改善。在9例患者中，括约肌切开术在5例中取得了非常良好的效果，其中2例将详细阐述作为例证。
