目的 通过比较和分析单纯声带肥厚和声带小结的嗓音参数的变化 ,评价这些参数在两种疾病中的诊断及疗效。方法 应用 Dr.Speech(DSS)软件对成人女性 30例单纯声带肥厚和声带小结患者做嗓音测试 ,对其主要声学参数进行比较分析。结果 声带小结的嗓音声学参数、基频微扰、声门噪声能量 NNE值均较声带肥厚的各指标高。其中声门噪声能量在声带小结中异常者占 99.6% ,声带肥厚占 80 % ,两组之间有显著性差异 (P<0 .0 5 )。基频微扰和振幅微扰的异常占有率 ,两组之间无显著性差异 (P>0 .0 5 )。结论 嗓音参数对诊断和区别声带肥厚和声带小结有一定的价值 ,特别是声门噪声能量有更高的敏感性 ,对诊断和治疗声带疾病有一定的价值
Objective To compare and analyze the changes of vocal parameters in simple vocal folds hypertrophy and vocal nodules to evaluate the diagnostic and therapeutic effects of these parameters in the two diseases. Methods Thirty patients with pure vocal folds and nodules in adult women were tested with Dr.Speech (DSS) software for voice tests. The main acoustic parameters were compared and analyzed. Results The voice acoustic parameters, fundamental frequency perturbation and glottal noise energy NNE values of vocal nodules were higher than those of vocal cord hypertrophy. In which the glottis noise energy in the vocal nodules were abnormal in 99.6%, vocal folds hypertrophy accounted for 80%, there was a significant difference between the two groups (P <0.05). There was no significant difference between the two groups (P> 0.05). Conclusions Voice parameters are valuable in diagnosing and distinguishing between vocal cord hypertrophy and vocal nodules. In particular, vocal noise energy is more sensitive and has certain value in the diagnosis and treatment of vocal cord diseases
