摘要
目的 探讨喉全切除术后食管言语的特点。方法 对北京同仁医院 40例训练食管发音患者的嗓音声学、言语、形态特征及发音时食管压力变化进行分析 ,以 5 0例健康男性作为对照。结果 食管发音不良 8例 ,发音良好 32例。发音不良者黏膜痉挛 ,气流无法送出 ;发音基频小于 6 0Hz无法评估。发音良好者食管入口黏膜松弛 ,振动明显 ;其嗓音声学特征与健康对照差异有显著性(P值 <0 0 5或 <0 0 1)。食管发音不良者训练发音年龄、言语清晰度、速度、呼吸发音协调程度与发音良好者差异有显著性 (P值 <0 0 5或 <0 0 1)。食管发音时食管上、中段压力明显高于健康对照组(P值 <0 0 5或 <0 0 1) ,其中发音不良者压力增加更为明显 ,特别是食管中段压力。结论 食管发音声道振动及动力器官均与正常发音存在本质区别 ,通过代偿机制瞬间发音可达良好效果 ,但在自然。
Objective To evaluate the characteristics of esophageal speech after total laryngectomy. Methods Esophageal speech evaluation of 40 cases of esophageal phonation included acoustic parameters, intraesophageal pressures during phonation, speech intelligibility, fluency, communication, respiratory sound and cognate distinctions between voiced and voiceless sounds. Results In 8 poor speakers, the neoglottis was spasmodic and difficult to vibrate during phonation. In 32 good speakers, the neoglottis was relaxed and easy to vibrate during phonation. The training age, speech intelligibility, fluency, communication, respiratory sound, cognate distinctions between voiced and voiceless sounds and intraesophageal pressures during phonation were significantly different between good and poor esophageal speakers. Vocal characteristics of good speakers differed significantly from those in the normal(P<0.05 or P<0.01). The upper intraesphageal pressure during esophageal phonation was higher than that of the normal, especially for poor esophageal phonation. The middle to lower intraesphageal pressures was highest during poor esophageal phonation. Conclusions Esophageal phonation was completely alaryngeal, and its activators also differ completely, so phonation could not maintain much longer. Patients with poor esophageal phonation could not drive the air through the neoglottis freely.
