The Effects Of Auditory Brainstem Response In The Diagnosis And Prognosis Of Sudden Sensorineural Hearing Loss

Objective: To explore the changes in amplitude of waveⅠ、latency of each wave 、wave interval of auditory brainstem response in patients with sudden sensorineural hearing loss,and analysis the relationship in these changes and hearing outcomes,in cording to supply clinical reference to diagnosis and treat this disease.Methods: Patients with SSNHL were adopted in otolaryngology from September 2019 to February 2021,and their relating clinical characteristics were recorded in detail,including gender,age,affected side,with or without vertigo and the types of vertigo,time from onset to treatment,hearing level before treatment,with or without hypertension and diabetes.Those having a previous history of otologic surgery in the affected ear,Meniere’s disease,hearing related organic disease,cerebrovascular crash,etc.such can result to hearing loss diseases,were excluded in the study.PTA and ABR were tested before treatment.According to patients’ clinical features and the data from ABR,Then analysis the influences of these characteristics and the indices of ABR in patients with sudden sensorineural hearing loss for the hearing outcome.Results: 1.140 SSNHL patients were included in this study,74 men,66 women.Effective hearing recovery was observed in 102 cases with systematic treatment,and the efficient is 72.9%.2.Wave Ⅰ,Ⅲ,and Ⅴ,latencies were significantly prolonged in the affected ears compared with the unaffected ears.A smaller waveⅠamplitude was found in the affected ear compared with the unaffected ear in the three recovery groups.3.There was a significant association between wave I latency and hearing outcome(p= 0.032)with a prolonged trend from complete to slight hearing recovery in the therapy group.Conclusion: 1.The incubation period of wave Ⅰ,Ⅲ,and Ⅴ of the affected ear was significantly prolonged before treatment.2.There was a significant correlation between wave I latency and hearing outcome in patients with SSNHL.The finding may provide diagnostic information and serve as potential diagnostic and prognostic indicator in patients with SSNHL.
