目的:分析总结临床中耳声发射正常的听觉障碍类型。方法:对83例听觉障碍患者行纯音听阈、阻抗、听性脑干反应(ABR)、40 Hz AERP、自发性耳声发射(SOAE)、瞬态耳声发射(TEOAE)、畸变产物耳声发射(DPOAE)测试及CT和(或)MRI扫描。结果:耳声发射(OAE)正常的听觉障碍包括:①听神经病68例;②听神经瘤2例;③皮层聋或中枢性聋3例;④听觉过敏2例;⑤功能性聋2例;⑥伪聋6例。结论:耳声发射检测在蜗后性聋、中枢性聋、非器质性聋和其他一些特殊类型听觉障碍的诊断和鉴别诊断中具有重要临床意义。
OBJECTIVE: To analyze and summarize the types of auditory disorders with normal middle ear acoustic emission. Methods: Eighty - three patients with hearing impairment underwent pure tone threshold, impedance, ABR, 40 Hz AERP, spontaneous otoacoustic emission (SOAE), transient otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE) test and CT and / or MRI scan. Results: The normal auditory disturbances of otoacoustic emission (OAE) included: ① 68 cases of auditory neuropathy; ② 2 cases of acoustic neuroma; ③ 3 cases of cortical deafness or central deafness; ④ 2 cases of auditory sensation; ⑤ 2 cases of functional deafness; ⑥ False deafness in 6 cases. CONCLUSION: Otoacoustic emission testing plays an important role in the diagnosis and differential diagnosis of idiopathic deafness, central deafness, non-structural hearing loss and other special types of hearing disorders.
