喉环上部分切除带蒂软骨膜环杓连接声门重建术后嗓音分析

The voice analysis of subtotal laryngectomy by pedicled flaps reconstruction of vocal cord

目的:观察喉环上部分切除带蒂软骨膜环杓连接声门重建术与其他行喉部分切除术术后1年以上 患者的发声质量进行比较。方法:采用上海泰亿格电子有限公司提供的Dr.Speech嗓音及语音分析,测试在环境 噪声控制在45dB以下的实验室中进行。测试前受试者进行发声训练,测试声样选择元音[ ],评估参数为:基频 微扰,振幅微扰,噪声能量。结果:观察喉环上部分切除带蒂软骨膜环杓连接声门重建术嗓音各项声学参数值均 较正常值明显增高,差异有统计学意义;与其他喉部分切除术后相比,参数明显降低,发声质量明显提高。结论: 喉环上部分切除带蒂软骨膜环杓连接声门重建术提高了发声质量,嗓音声学分析可作为评价喉癌术后发声质量 的定量指标,有助于术后发声质量的客观评价。

Objective:To compare the voice quality of patient's after surgery over one year between the reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps and other laryngeal function in subtotal laryngectomy.Method:By using Dr Speech's acoustic analysis software, the noise level of the testing room was controlled under 45 dB. Before testing, patients have pronounced training. The testing voice was selected as[].The evaluation parameters were jitter,shimmer, and NNE.Result:All the acoustic parameters of the reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps were increased distinctly than normal.There were statistical significant differences;compared with those by subtotal laryngectomy, the parameters decreased distinctly, and the voice quality improved distinctly.Conclusion:The reconstruction of laryngeal function in subtotal laryngectomy by pedicled flaps improve the voice quality, the acoustic analysis can be a measurable data of the postoperative voice quality evaluation, and administer to its objective evaluation.
