摘　　要：目的 :探讨电声门图 (EGG)和声学测试参数值与嗓音疾病诊断的相关性。方法 :采用EGG及声学测试两种检测方法对 2 0 7例正常人和 2 96例喉部疾病患者进行测试。运用Dr .Speech 3.0软件 ,计算出嗓音声学分析参数 ,并对数据进行统计学分析。结果 :声带息肉和声带小结患者的振幅微扰 (shimmer)和频率微扰 (jitter)变化率相近 ,但shimmer的敏感度较jitter更高。声带息肉、声带小结、喉鳞状细胞癌与对照组相比 ,习惯基频、jit ter和shimmer增大 ,谐噪比减小。喉鳞状细胞癌患者接触幂值高于对照组 ,接触率与之比较差异无统计学意义。结论 :EGG和声学测试参数值及波形的变化可为喉部疾病的诊断提供客观的量化指标。Objective:To explore the relationship between electroglottography/ acoustic test parameter and disease diagnosis.Method:3.0 software by Dr.Speech was used to test synchronically the electroglottography and acoustic test parameter of 503 cases so as to make a statistical analysis and comparison.Result:The shimmer was similar with the jitter on the inspection of polyp of vocal cord and vocal nodules,but the shimmer was more susceptive than the jitter.Compared with the healthy group,mean F 0,jitter and shimmer of polyp of vocal cord increased, while the Harmonic-to-Noise decreased,so did the vocal nodules and carcinoma of larynx. Compared with the normal,the contact index of carcinoma of larynx increased, but the contact quotient remained on the same level.Conclusion:EGG, acoustic test number comparison and wave change provide an objective quantized index for the diagnosis of laryngeal diseases.
