[Cortical evoked auditory evoked potentials in a series of patients who had bacterial meningitis during childhood].
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.
