The Groningen and Provox tracheo-oesophageal valve voice prostheses have been used in post-laryngectomy patients extensively in Sheffield since 1986 and 1990, respectively. To the present time a total of over 40 patients have made use of these devices, two thirds of whom underwent insertion at the time of laryngectomy. Prostheses were replaced under local or general anaesthesia if they were leaking or if phonation became increasingly difficult. Our experience with over 200 valves including the Groningen High Resistance, Groningen Low Resistance and Provox prostheses in this patient group is presented. We believe that the primary insertion of a low resistance prosthesis, either the Provox or Groningen Low Resistance device, is the method of choice in speech rehabilitation following laryngectomy.
自1986年和1990年以来，格罗宁根（Groningen）和普罗沃克斯（Provox）气管食管瓣膜语音假体分别在谢菲尔德的喉切除术后患者中得到广泛应用。截至目前，共有40多名患者使用了这些装置，其中三分之二的患者在喉切除时植入了该装置。如果假体出现泄漏或发声变得越来越困难，则在局部或全身麻醉下更换假体。本文介绍了我们在该患者群体中使用200多个瓣膜的经验，包括格罗宁根高阻力瓣膜、格罗宁根低阻力瓣膜和普罗沃克斯假体。我们认为，初次植入低阻力假体，即普罗沃克斯或格罗宁根低阻力装置，是喉切除术后言语康复的首选方法。
