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 (1) 68 patients with auditory neuropathy; (2) 2 patients with unilateral acoustic neuroma; (3) 3 patients with cortical deafness or central hearing loss; (4) 2 patients with hyperacusis; (5) 2 patients with functional deafness; (6) 6 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 other special hearing disorders.
目的
分析并概述正常耳声发射情况下听力障碍的模式。
方法
对83例听力障碍患者均进行了纯音听力测试、声阻抗测试、听性脑干反应（ABR）、40赫兹听觉事件相关电位（40Hz AERP）、自发性耳声发射（SOAE）、瞬态诱发耳声发射（TEOAE）、畸变产物耳声发射（DPEOAE）以及CT/MRI扫描成像检查。
结果
正常耳声发射情况下听力障碍的模式包括：（1）68例听神经病患者；（2）2例单侧听神经瘤患者；（3）3例皮质聋或中枢性听力损失患者；（4）2例听觉过敏患者；（5）2例功能性聋患者；（6）6例诈聋患者。
结论
耳声发射测试在蜗后性聋、中枢性听力损失、非器质性听力损失及其他一些特殊听力障碍患者的诊断及鉴别诊断中发挥重要作用。
