对喉癌、喉咽癌及颈段食管癌等患者进行喉全切除术后,必然导致发音机能的丧失。由于严重影响病人的生活和工作而造成终生痛苦,一些喉癌病人因不愿丧失会话能力而拒绝手术。因此,研究和解决喉全切除术后发音机能的重建问题,就具有重要的意义。从1859年起,即有不少人利用各种人工喉的设计及食管发音的训练以恢复喉切除术后的发音功能。但到目前为止,这两方面的成就还不能满足无喉头病人的全部需要。木村于1968年调查了50例
Laryngeal cancer, hypopharyngeal cancer and cervical esophageal cancer patients after laryngectomy, will inevitably lead to the loss of pronunciation function. Some patients with laryngeal cancer decline to surgery because they do not want to lose their ability to engage in conversation because of the lifetime-long suffering caused by their serious impact on their lives and work. Therefore, it is of great significance to study and solve the reconstruction of pronunciation function after total laryngectomy. Since 1859, many people have used various artificial throat designs and esophageal pronunciation training to restore the pronunciation function after laryngectomy. So far, however, these two achievements have not met the full needs of non-throat patients. Kimura investigated 50 cases in 1968
