Abstract
Following meningitis, 280 children (168 boys, 112 girls) had audiological assessment, and 87 (31%) were initially found to have a sensorineural hearing loss in one or both ears. Twenty-three children were followed elsewhere. Of 64 children followed for an average of 3.46 years, 55 (86%) exhibited stable auditory thresholds over time, most commonly (24) bilateral, profound/anacusic losses. One moderate and four severe losses were identified, but no bilateral, mild losses. Nineteen children had asymmetric losses with varied audiometric configurations. Seven children presented with a unilateral hearing loss, again with a range of configurations. Auditory thresholds changed over time in nine children, either improving, declining, or fluctuating, over a variable interval ranging from 1 month to 12 years.
