Abstract:
Objective The diagnosis of low frequency sensorineural hearing loss is examined for clinical applications.Methods Pure tone threshold(PTT),acoustic impedance,auditory brainstem response(ABR),distortion product otoacoustic emissions(DPOAE),electrocochleogram(ECochG)and imaging examinations of CT or MRI were performed on 56 cases with low frequency sensorineural hearing loss.Results Among 56 cases of low frequency sensorineural hearing loss,38 cases with sudden low frequency sensorineural hearing loss,9 with Meniere's disease, 6 as auditory neuropathy,1 case of acoustic neuroma,1 case of multiple sclerosis and 1 case with arachnoid cyst of cerebellar hemisphere surface.Conclusion Low frequency sensorineural hearing losses occurred in varied diseases.A comprehensive approach should be taken to diagnose this hearing loss and if necessary,CT or MRI can be utilized to confirm the standard audiologic evaluations.
