| 摘 要： | 目的:分析耳鸣与耳蜗毛细胞早期损害的关系,探讨耳鸣的客观检查手段.方法:实验组为40例(66耳)纯音听力正常的耳鸣患者,对照组为40例(80耳)听力正常无耳鸣的正常人,二组均行诱发性耳声发射检查:瞬态耳声发射(TEOAE)和畸变产物耳声发射(DPOAE)检查.结果:1.TEOAE通过率,对照组为100%,实验组为42.4%,两组有显著性差异(P＜0.01);2.DPOAE通过率,对照组为100%,实验组为51.5%,两组有显著性差异(P＜0.01).结论:部分听力正常的耳鸣患者已有耳蜗毛细胞的损害;TEOAE及DPOAE可以作为外周性耳鸣诊断的一种客观检测方法.

| Abstract: | Objective:To investigate the relationship between tinnitus and early harmness of outer hair cell in cochlear.To find the objective methods for tinnitus exploration.Methods:The study group included 40 cases(66 ears) of normal hearing with tinnitus,The control group consisted of 40 cases(80 ears) of normal hearing without tinnitus.Both group were tested by evoked otoacoustic emissions(TEOAE and DPOAE).Results:1.The passing rate of TEOAE was 100% in the control group,42.4% in the study group,Significant differences exist between the two groups(P<0.01);2.The passing rate of DPOAE was 100% in the control group,51.5% in the study group.Significant differences exist between the two groups(P<0.01).Conclusion:Some patients of normal hearing with tinnitus have had early harmness of outer hair cell in cochlear.Evoked otoacoustic emissions is one of worthy methods to evaluated objectively the tinnitus. |
