Abstract:Objective To investigate the effectiveness of combination of application of auditory brainstem response(ABR)and pure tone audiometry(PTA)in the diagnosis and prognosis of sudden deafness.Methods Altogether 50 cases of patients with sudden deafness(53 ears)who were treated in our department from March 2016 to March 2017 underwent pure tone audiometry were selected,and their curve features included low frequency descent type (14 ears),high frequency descent type(13 ears),flat type(17 ears)and extremely severe type(9 ears).Corresponding treatment was given according to the different types,with 14 days for a course of treatment,and then the curative effect was determined.At the same time,ABR of sudden deafness patients was detected to observe the correlation between ABR threshold and subjective thresholds.The therapeutic effect was also observed between sudden hearing loss patients without ABR waveform(group A,15 ears)and with ABR waveforms(group B,38 ears).Results After treatment,17 ears of patients with sudden deafness were cured,14 ears showed effect and 8 ears were effective.The total effective rate of treatment was 73.58%.The threshold of group B patients with ABR waveforms was 10 to 20 dB which was higher than that of subjective threshold,with a good correlation(Y=1.8623-0.8741X,r=0.8741).The total effective rate of group A was 33.33%,and group B was 89.45%,with significant difference between the two groups(χ2=6.603,P=0.005).Conclusion Combination of application of ABR and PTA not only can be used for the diagnosis and classification of patients with sudden deafness,ABR also can be used as indicators to predict the prognosis of sudden deafness.Patients with ABR waveform have good treatment effect,while,patients without ABR waveform have bad treatment effect.
