Hearing Alterations following Meningitis. 2. Variable Hearing

Eight patients with variable hearing after meningitis are presented. Four patients had had Haemophilus influenzae meningitis, three had meningococcal meningitis, and in one instance, the etiological agent remained unknown. In five cases, the hearing fluctuated markedly, probably because of endolymphatic hydrops. In three cases, the hearing deteriorated temporarily after a free period of 6 to 1 2 months.
