摘要
目的探讨耳呜与各种听力学检查的关系，探索耳鸣的客观诊断方法。方法选取听力正常耳鸣患者38例56耳作为实验组，选取无年龄及性别差异的25例50耳听力正常且无耳鸣的志愿者作对照组，分别检测两组对象的纯音测听、声导抗测试、耳鸣检查、畸变产物耳声发射（DPOAE）、昕眭脑干反应（ABR），并进行统计学分析。结果听力正常耳鸣组与对照组DPOAE的通过率有统计学意义，耳鸣组（67．3％）低于对照组（96．0％、在700Hz、1KHz、4KHz、6KHz及8KHz耳鸣组DPOAE幅值低于对照组（P〈0．05）耳鸣组ABRI、Ⅲ、V波潜伏期及Ⅲ－V波间期与对照组相比有所延长，差异有显著性（P〈0．05）耳鸣组平均后效抑制阳性率为64．3％，其中耳呜掩蔽曲线为汇聚型者掩蔽效果较好。结论DPOAE可以先于纯音测听发现耳蜗功能的早期改变，对耳鸣患者行DPOAE和ABR测试可以帮助对部分耳鸣进行病变部位的诊断。
Objective To find the relationship between tinnitus and each testing method, and provide information for its diagnosis and treatment. Methods Compared the characteristics of audiology tests, including pure tone audiometric, acoustic immittance, middle ear muscle reflexes, matching test,distortion products otoacoustic emission （DPOAE）, and auditory brainstem response（ABR）. Results The detection rates of DPOAE were 67.3% in patients of normal hearing tinnitus groups, which were significant lower than those in control group. Comparing with the control group, the normal hearing tinnitus group performed PL of wave I, III, V and IPL of III-V prolonged.Conclusion DPOAE can reflect cochlear hair cells＇ lesion in early stage; DPOAE and ABR test are helpful for diagnosis of lesions in some tinnitus patients.
