摘要
目的比较喉癌及声带息肉患者主要嗓音参数在不同检测方法中的变化,探讨喉癌与声带息肉对发声功能的影响。方法采用Dr.Speech Science for Windows(4.0)软件对正常成人、喉癌患者、声带息肉患者作嗓音声学分析和电声门图检测,并比较其主要参数的变化,分析各自嗓音质量评估的特点。结果①在喉癌和声带息肉患者中,两种嗓音检测方法的嗓音参数,基频微扰、振幅微扰、声门噪声能量均是有价值的,两者的基频微扰、振幅微扰、声门噪声能量可以互相替代,两种方法各参数间比较无统计学差异;②正常成人、喉癌患者、声带息肉患者平均基频之间无统计学意义,基频微扰、振幅微扰、声门噪声能量数值由低到高排列依次为正常成人组、声带息肉组、喉癌组,两两比较均有显著性差异(P<0.05);③嗓音质量由好到差排列为正常成人组、声带息肉组、喉癌组。结论计算机声学分析的各项参数可作为嗓音定量评价的客观指标,判断嗓音损害程度。
OBJECTIVE To analyze the voice and electroglottography （EGG） parameters in patients with vocal cord polyps and laryngeal cancer and to assess the voice parametric characteristics of laryngeal diseases. METHODS The computer multimedia program of Dr. Speech Science for Windows was used to obtain the voice analysis and EGG parameters in healthy adults and patients with vocal cord polyps and laryngeal cancer. The acoustic features of vocal cord polyps and laryngeal cancer were analyzed. RESULTS 1.The jitter, shimmer and NNE of voice and EGG were valuable in the objective differentiation of laryngeal diseases. 2.The jitter, shimmer, and NNE values in patients with vocal cord polyps and laryngeal carcinoma were obviously higher than those in normal controls （P〈0.05 and their F0 value was similar to those in normal controls. The jitter, shimmer, and NNE values in patients with laryngeal carcinoma were higher than those in patients with vocal cord polyps. 3.The voice of adults had distinctive characteristics among laryngeal diseases. CONCLUSION The acoustic parameters can be used as objective standards for quantitative evaluation of voice function.
