A rare case of laryngectomee who acquired TE shunt speech is reported. Our patient was a 64-year-old woman with laryngeal cancer (glottic type T3N0M0). She underwent laryngectomy in 1990, and a Komorn tracheo-esophageal shunt operation was performed simultaneously. A voice prosthesis (BIVONA) was inserted into the shunt, but the voice valve was not used. She acquired shunt speech soon after the operation, and there was no need to close the tracheostoma during phonation. Fiberoptic, X-ray and aerodynamic findings of the shunt and esophagus were as follows: (i) The one-way valve of the voice prosthesis was open during inspiration and closed during phonation. (ii) Swallowing of air, as seen in esophageal speech, was not observed. (iii) The neoglottis was in the upper part of the esophagus. It was concluded that the air for the vibration of the neoglottis entered the esophagus through the T-E shunt during inspiration.
报告了一例获得性经食管分流语音的喉切除患者的罕见病例。我们的患者是一名64岁女性，患有喉癌（声门型T3N0M0）。她于1990年接受了喉切除术，并同时进行了Komorn气管食管分流手术。在分流处插入了一个语音假体（BIVONA），但未使用语音瓣膜。术后她很快就获得了分流语音，发声时无需关闭气管造口。分流和食管的纤维喉镜、X线及空气动力学检查结果如下：（i）语音假体的单向瓣膜在吸气时打开，发声时关闭。（ii）未观察到食管语音中出现的空气吞咽现象。（iii）新声门位于食管上部。得出的结论是，吸气时用于新声门振动的空气通过气管食管分流进入食管。
