| 摘 要： | 目的：研究瞬态耳声发射(TEOAE)在高频区域的临床应用价值及与纯音测听听力检查的相关性。方法：应用耳声发射测试仪检测正常组和高频听力损失组高频区域的TEOAE各频段平均强度；应用纯音听力计检测各频率点的纯音听阈值，比较两者的变化趋势。结果：TEOAE在1．5～4．5kHz高频范围内，正常组与高频听力损失组的耳声发射平均强度差异有统计学意义，与纯音听阈检查结果有一定的相关性。两种检查中，高频听力损失组的两个指标变化趋势相一致。结论：临床上，结合纯音电测听结果，可使TEOAE更为准确客观地判断患者高频区域听力损失的程度和范围。

| Abstract: | OBJECTIVE: To evaluate the clinical use of transiently evoked otoacoustic emissions (TEOAE) in patients with high-frequency sensorineural hearing loss, comparing the result of TEOAE with audiometry to find the correlation between them. METHOD: Fourteen normal adults and 25 patients with high-frequency hearing-loss were measured with TEOAE25 analyzer system and OB822 audiometer respectively, to compare the changing trend of the two examinations. RESULT: In the domain of 1.5 to approximately 4.5 kHz, there was significant difference of TEOAE between normal cases and hearing-loss cases. The results of TEOAE and audiometry had correlation with each other. The changing trend of the two examinations was accordant. CONCLUSION: Combined with pure tone audiometry, TEOAE could discover the degree and range of high-frequency hearing loss more correctly. |
