两种无喉言语的比较研究

Comparison of Two Kinds of Alaryngeal Speech

目的 比较无假体气管食管分流音与食道音在最大发声时间、可懂度和阅读时间等方面的差异。方法 研究对象包括年龄、性别和术后发声时间相当的两组无喉言语者。其中 ,食管音组 2 1名 ,无假体气管食管音组 3 0名。采集了两组的最大发声时间、可懂度和阅读时间的数据。用t检验分析最大发音时间和阅读时间 (P <0 .0 5 )。H检验分析言语可懂度 (P <0 .0 5 )。结果 食管音在这三个项目上均较气管食管分流音差 ;言语可懂度略差于气管食管分流音 ;言语流利度和最大发声时间均明显差于气管食管分流音。结论 无假体气管食管音的言语效果优于食管音 ,而且其手术方法简单 ,容易训练 ,利于推广。

Objective To compare the differences in maximum phonation time(MPT),speech intelligibility,reading time between esophageal speakers and tracheaoesophageal shunt speakers without prosthesis(TE speakers).Methods Two groups included 21 esophageal speakers and 30 TE speakers,which were matched in age,sex and years after total laryngectomy.According to our method , the data of two groups on MPT,speech intelligibility and reading time were collected.T test analyzed MPT and reading time;H test analyzed speech intelligibility.Results Esophageal speech was inferior to TE speech in three aspects.MPT of esophageal group was apparently shorter than that in TE group;Reading time of esophageal group was obviously longer than that of TE group.Speech intelligibility of esophageal speakers was slightly worse than that of TE speakers.Conclusion TE speech is superior to esophageal speech.The surgical approach of TE shunt speech without prosthesis is simple and TE speakers are easily to be trained,so we should use the approach in all laryngological surgery.
