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 observe the sound quality of patients with partial resection of pedicled perichorhexis of the laryngeal ring with glomerulus link glottic reconstruction compared with other patients who underwent laryngectomy for more than one year. Methods: The Dr.Speech voice and speech analysis provided by Shanghai Taiyige Electronics Co., Ltd. was conducted in a laboratory with an ambient noise control below 45dB. Vocal training was performed on the subjects before the test, and the vowel [] was selected for testing the sound samples. The evaluation parameters were: fundamental frequency perturbation, amplitude perturbation, and noise energy. RESULTS: The acoustic parameters of the vocal cords in the laryngeal ring were significantly higher than those in the normal group (P <0.05), and the difference was statistically significant. Compared with other laryngectomy, the parameters were significant Reduce, sound quality improved significantly. Conclusion: Part of the laryngeal ring excision of the pedunculated perichordal cricoaryngeal ring to improve the sound quality, voice acoustics analysis can be used as a quantitative indicator of postoperative laryngeal sound quality, contribute to the objective evaluation of postoperative vocal quality.
