Comparison between brainstem-evoked response audiometry and behavioral audiometry in 270 infants and children.
The authors refer their results obtained with brainstem-evoked response audiometry (BSERA) and behavioral audiometry in a group of 270 children (aged from 6 months to 12 years) divided into subjects with (group A) and without (group B) reliable audiograms. In group A an agreement between the two methods was found in 77% of cases and a serious discrepancy in 5%. In group B an agreement was found only in 34% of cases, while a serious discrepancy was found in 20% of the children. BSERA was useful because many diagnostic mistakes were avoided. The authors think that BSERA is a reliable technique, as their data show, but in at least 4 cases they found that BSERA gave a hearing level much higher than that obtained with behavioral audiometry or that observed in the children's responses to everyday sounds. Since click gives only partial information of the tonal field and because it is possible to make technical mistakes, the authors believe that BSERA must not be used as the only diagnostic test but that it should be part of a test battery which includes, at least, behavioral audiometry and impedance audiometry.
