The function of the pharyngo-oesophageal sphincter in patients subjected to total laryngectomy has been evaluated by manometric measurement, and the results related to the patient's ability to speak with an oesophageal voice, as well as to the occurrence of dysphagia. Seventeen totally laryngectomized patients were studied. The intelligibility of the patient's oesophageal voice was classified according to the scale: good (group IV), middle (group III), poor (group II) and unintelligible (group I). The manometric investigation was carried out with a continuously perfused low compliance system with three side holes, and the results of the patient investigation were compared with those from a normal material. It was possible in three patients only to demonstrate a resting tone corresponding to the pharyngo-oesophageal sphincter. The pressure was lower in these patients than in the normal material. No correlation was found between any of the three parameters: sphincter pressure, intelligibility, and the presence of dysphagia.
通过测压测量评估了全喉切除患者咽食管括约肌的功能，并将结果与患者用食管语音说话的能力以及吞咽困难的发生情况相关联。研究了17例全喉切除患者。根据以下标准对患者食管语音的清晰度进行分类：良好（IV组）、中等（III组）、较差（II组）和无法理解（I组）。使用带有三个侧孔的连续灌注低顺应性系统进行测压研究，并将患者研究结果与正常样本的结果进行比较。仅在三名患者中能够证实存在与咽食管括约肌相对应的静息张力。这些患者的压力低于正常样本。在括约肌压力、清晰度和吞咽困难的存在这三个参数之间未发现相关性。
