目的 :探讨声带息肉患者声学参数值的变化与手术疗效的关系。方法 :采用 Dr.Speech软件 ,对 80例声带息肉患者于术前、术后进行测试 ,经计算测得所需要的主要声学参数与已建立的正常嗓音和病理嗓音数据库进行比较分析 ,判断受测嗓音是否正常。结果 :80例声带息肉患者中 ,其主要声学参数基音频率微扰 (jitter)、基音振幅微扰 (shim mer)及声门噪声 (NNE)术前较高 ,术后较低 ,分别与术前比较 ,其差异均有极显著性意义 (P <0 .0 1) ;术后第 1周分别与术后第 2周和第 4周相比较 ,其差异亦有显著性意义 (P <0 .0 5或 0 .0 1)。在 3个声学参数中以 NNE的敏感性最高。结论 :NNE,shimmer值变化对手术疗效观察有较大意义。
Objective: To investigate the relationship between the change of acoustic parameters and the curative effect in patients with vocal cord polyps. Methods: Eighty patients with vocal cord polyps underwent preoperative and postoperative tests using Dr.Speech software. The main acoustic parameters required by the calculation were compared with the established normal voice and pathological voice databases to determine whether the measured Is the voice normal? Results: In 80 patients with vocal cord polyps, the jitter, jimmer and glottal noise (NNE) of the main acoustic parameters were higher before operation and lower after operation, (P <0.01). There was also a significant difference between the first week and the second week and the fourth week after operation (P <0. 0 5 or 0 .0 1). Among the three acoustic parameters, NNE was the most sensitive. Conclusion: The changes of NNE and shimmer values have great significance in the observation of curative effect.
