耳声发射正常的听觉障碍类型

Patterns of hearing disorders in normal otoacoustic emissions

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 outline patterns of hearing disorders in normal otoacoustic emissions. Method：Tests of pure tone audiometry , acoustic impedance test,auditory brainstem response （ ABR ）, 40 Hz AERP,spontaneous otoacoustic emissions （SOAE）, transient evoked otoacoustic emissions （TEOAE）, distortion evoked otoacoustic emissions （DPEOAE）and imaging examinations of CT/MRI scan were performed on all 83 patients with hearing disorders. Result：Patterns of hearing disorders in normal otoacoustic emissions including ①68 patients with auditory neuropathy;②2 patients with unilateral acoustic neuroma;③3 patients with cortical deafness or central hearing loss;④2 patients with hyperacusis;⑤2 patients with functional deafness;⑥6 patients with malingering. Conclusions：OAE tests play an important role in diagnosis and differential diagnosis of the patients with retrocochlear deafness, central hearing loss, nonorganic hearing loss and some orther special hearing disorders.
