喉全切除术后发声重建是目前研究中一个比较活跃的领域。应用外科方法插入硅胶发声假体以重建气食管通道是喉全切除患者发声重建的一个重要进步,其成功率高,发声效果好,已被广泛应用于临床。然而,由于其表面生物膜的形成,硅胶发声假体存在着生物变质的问题,需要定期更换,这给患 Vocal reconstruction after total laryngectomy is an active area in the current study. Surgical insertion of silicone phonation prosthesis to reconstruct the esophageal aisle is an important step in vocal reconstruction of patients undergoing total laryngectomy. The success rate is high and sounding effect is good. It has been widely used in clinical practice. However, due to the formation of its surface biofilm, there is a problem with the biodegradability of the silicone phonation prosthesis that needs to be replaced regularly, which gives the affected
