Cortical auditory evoked potentials (CAEP) were recorded from scalp electrodes in 47 patients, who survived to bacterial meningitis in their childhood. CAEP were obtained from 1 month to 8 years after recovering from acute disease. Neisseria meningitidis was the microorganism more frequently isolated from CSF (43.5%). Exclusively abnormal values in amplitude of CAEP were registered in 15 cases (32%), mainly at the lower tones explored; 14 of them were subjected to conventional audiometric test, which demonstrated unilateral hearing loss only in 2. No alterations in the latency of P2 wave were seen. We recommend to include CAEP in search of hearing disorders in younger children after recovering from meningitis, since they can detect lesions in cortical-subcortical auditory tracts, which otherwise could go unnoticed.
对47例童年期患细菌性脑膜炎后存活的患者，通过头皮电极记录皮层听觉诱发电位（CAEP）。CAEP是在急性病康复后1个月至8年期间获得的。脑膜炎奈瑟菌是脑脊液中最常分离出的微生物（43.5%）。15例（32%）记录到CAEP振幅值完全异常，主要出现在所检测的低音调；其中14例接受了传统听力测试，仅2例显示单侧听力损失。未观察到P2波潜伏期有改变。我们建议在脑膜炎康复后的幼儿中进行CAEP检查以寻找听力障碍，因为它们可以检测到皮层-皮层下听觉通路的病变，否则这些病变可能会被忽视。
