全喉截除术后一般多建议以发食管音来重建语言,但它所发之声音在强度、音调及讲话速度等均有一定限制,有50%以上患者不能发出食管音。1979年S inger与Blom提出以内窥镜经气管食管穿刺,安装硅胶发音装置的方法,既能产生由肺提供的单向气流的语音,又能防止食物误吸入气道。采用此法后,能使93%的全喉截除术患者,重建语言。作者对正常喉、食管、气管食管三种发音,在声音强度、频率及速度三方面进行分析比较。第一组受试者,为全喉术后以气管食管发音
It is generally recommended to reconstruct the speech by transesophageal echocardiography after total laryngectomy, but the sound of it is limited in intensity, tone and speed of speech, and more than 50% of patients can not emit esophageal tone. In 1979, S inger and Blom proposed endoscopic tracheal esophageal puncture, installation of silicone sounding device method, both to produce unilateral airflow from the lungs of the voice, but also prevent food aspiration into the airway. With this method, 93% of patients with total laryngectomy can rebuild language. The author of the normal throat, esophagus, tracheoesophageal three pronunciations, in the three aspects of sound intensity, frequency and speed analysis and comparison. The first group of subjects was transurethral esophageal after total laryngectomy
