食管充气试验在二期发音重建中的作用

Esophageal insufflation test in secondary voice reconstruction

目的尽快恢复无喉者语言功能，减少手术创伤，提高预测二期发音重建手术成功的准确性，客观评价食管充气试验的实际临床意义。方法对全喉切除术后无喉者行食管充气试验及二期发音重建，特别就食管充气试验阴性患者进行研究分析。结果４５例食管充气试验阴性患者行二期发音重建，而不行咽缩肌切断术的发音成功率９４％（３６／３８），阳性患者成功率１００％（７／７）；无论充气试验阴性或阳性患者术后发音效果均好于预测试验时。结论食管充气试验对预测术后发音具有一定参考意义，可作为ＢｌｏｍＳｉｎｇｅｒ法二期发音重建术前常规检查，但测试时因受诸多因素影响，不能作为判定术后发音效果的唯一依据。

Objective To restore the alaryengeal patients' enunciation function, reduce operative trauma, increase the accuracy of detecting the success of secondary voice restoration and evaluate objectively the practical clinical significance of esophageal insufflation test. Methods Esophageal insufflation test and secondary voice restoration were done for 45 alaryngeal patients, especially those with negative results of esophageal insufflation tests. Results It showed that the success rate of voice rehabilitation in patients with negative insufflation test but no intact pharyngeal constrictor was 94.7%(36/38), in those with positive insufflation test was 100%(7/7) uniformly. The postoperative pronounciation performance was better than that at the test time. Conclusion Esophageal insufflation test is a useful procedure in predicting the postoperative pronunciation,but could be influenced by many factors ,so it can not be used as the only test for estimating the postoperative pronunciation.
