Bacterial meningitis is the most common cause of post-natal acquired hearing loss in children. Although cochlear implantation helps in improving the hearing in these patients, the fibrosis and ossification of the cochlear lumen that occurs as a result of bacterial meningitis, limits the chances of successful implantation. In developing countries like India, the reduced awareness, limited resources, and financial constraints warrant judicial use of radiological and audiological tests to increase the rate of successful cochlear implantation. The present paper is a review of the literature and a proposed protocol for follow-up of post-meningitis patients to help clinicians diagnose and hence, intervene early when profound hearing loss occurs. Every patient who has had an episode of bacterial meningitis must be followed up for atleast 2 years for possible hearing loss with frequent audiological and radiological evaluation, as required. Cochlear implantation must be done as early as possible when profound hearing loss is detected.
