喉癌患者于全喉切除后失掉了发音机能,严重影响了工作与生活,带来了一定痛苦,尤其对不识字者更甚。因而有些患者不愿丧失说话能力而拒绝手术治疗。虽然人工喉能解决其发音问题,但因其音调、音色与正常人有所差别,且应用时有不便之处,以致部分患者不愿应用。亦有人运用食管发音,但需经过一段较长时间的耐心训练,发音仍是单调,语句不能连贯,并伴有呼吸音。即是如此,仍有30％左右患者尚不能恢复语言能力。 Laryngeal cancer patients lost their speech function after total laryngectomy, severely affecting work and life and causing some pain, especially for those who are illiterate. As a result, some patients refuse to lose speech and refuse surgery. Although the artificial larynx can solve its pronunciation problem, but because of its tone, timbre and normal people are different, and the application of inconvenience, so that some patients are reluctant to apply. Some people also use esophageal pronunciation, but after a long period of patient training, the pronunciation is still monotonous and the sentences cannot be coherent and accompanied by breath sounds. That is to say, there are still 30% of patients still unable to recover their language skills.
