Audiologic Comprehensive Evaluation of Sensorineural Deafness in Children / 听力学及言语疾病杂志

ABSTRACT

Objective To study the clinical application of the complete audiologic evaluation battery consisting of ABR,ASSR and behavioral audiometry in sound field for the identification of sensorineural losses in children.Methods In the study 48 children were divided as group PTA of the children assessed by pure tone audiometry and ABR and ASSR test,and group BA of the children unable to perform on behavioral evaluations.Results The analysis of the audiometric results of group PTA showed significant correlation between the ASSR thresholds and pure tone thresholds(P＜0.01) at various frequencies.The correlation coefficients were 0.75,0.76,0.76,and 0.83 at different frequencies.The ASSR-PTA linear regression was utilized.The comparison of the ABR and ASSR results of group BA indicated that 23 ears responded in ASSR but without responses in ABR.Those without ASSR responses also had no ABR There were 116 tests in total four frequencies for the 29 ears.83 responses were obtained from ASSR,89 responses from behavior audiometry and 96 from the use of the both tests.Conclusion The comprehensive audiologic evaluation battery could be used to test younger children with severe heating loss children as compared to the pure tone audiometry alone.More detailed data can be obtained thus from children to assist in rehabilitation in a more effective mariner.
