Brainstem electric response (BSER) and electrocochleography (ECochG) thresholds were measured in 55 ears of 46 'difficult-to-test' children. In most cases there was a reasonably close correlation between the two tests with BSER being less sensitive on the whole, but there was a small group, clinically indistinguishable from the majority, in whom an unacceptable discrepancy occurred. It was found that where the BSER threshold was equal to or less than 30 dB, the ECochG thresholds confirmed normal hearing, whereas if it was more than 30 dB further objective testing was essential to establish a definitive diagnosis of a hearing loss.
对46名“难以测试”儿童的55只耳朵进行了脑干电反应(BSER)和耳蜗电图(ECochG)阈值测量。在大多数情况下,两种测试之间存在合理的密切相关性,总体而言BSER不太敏感,但有一小部分儿童,临床上与大多数儿童无法区分,在他们身上出现了不可接受的差异。研究发现,当BSER阈值等于或小于30 dB时,ECochG阈值证实听力正常,而如果大于30 dB,则需要进一步的客观测试以明确诊断听力损失。
