电声门图测试对声带占位性病变的筛查价值

目的 探讨电声门图(electroglottography，EGG)测试在声带占位性病变中的筛查价值。方法 对134例声门型喉癌、167例声带良性病变(包括113例声带息肉、17例声带囊肿和37例声带白斑)及62名健康志愿者进行EGG测试，进行组间和组内比较，分析EGG测试的敏感性和特异性。结果 声带良性病变和喉癌组EGG波形和参数多数异常，与健康组之间有显著性差异，且良恶性病变组间亦有差异。但良性病变组内即息肉、囊肿和白斑之间，以及喉癌组内不同T分期之间EGG波形和参数差异多数无统计学意义。结论 电声门图测试在声带占位性病变的筛查中具有较高的敏感性，对区分良恶性病变亦有一定的特异性，但对病变类型和期别的划分无价值。

Effects of Electroglottography on Screening Vocal Fold Disorders

Objective To study the effects of Electroglottography(EGG) on screening vocal fold disorders.Methods 134 cases of glottal carcinoma and 167 benign vocal diseases and 62 healthy volunteers were measured. EGG waveform and variables were analyzed to investigate the sensitivity and specificity of EGG measurement.Results Compared with healthy people, the majority of EGG waveform and variables of vocal fold disorders were abnormal. The differences were significant statistically either between healthy people and vocal fold disorders or between benign vocal diseases and malignancy. In benign vocal diseases, the differences of EGG waveform and variables among vocal polyp and cyst and leukoplakia were insignificant statistically, and nor were the differences among various clinical T stages in glottal carcinoma.Conclusion EGG measurement is sensitive to screen vocal fold disorders, and is specific to distinguish benign and malignant diseases, but it couldn not be used to identify the types or clinical stage of the diseases.
