目的 :探讨电声门图 (EGG)的波形变化对喉部疾病的诊断价值。方法 :采用Dr .speech 3.0软件对12 0例声带息肉、4 2例声带小结、2 1例单侧声带麻痹、4 2例声门型喉癌及 38例Reink’s水肿等 5种喉部疾病患者进行EGG测试 ,对其波形变化进行分析。结果 :不同病变的EGG显示出不同的特殊波形 ,表现出较高的敏感性和特异性。结论 :EGG波形的变化对喉部疾病的诊断提供了客观的量化指标
Objective: To investigate the diagnostic value of EGG waveform changes in laryngeal diseases. Methods: Dr. Speech 3.0 software was used in the treatment of 50 laryngeal diseases, including vocal cord polyps, 42 cases vocal nodules, 21 unilateral vocal cord paralysis, 42 cases of glottic cancer and 38 cases of Reink’s edema. EGG test, analyze its waveform changes. Results: The EGG of different pathology showed different special waveforms, showing higher sensitivity and specificity. Conclusion: The change of EGG waveform provides an objective quantitative indicator of laryngeal disease
