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.
