The timing of insertion of a cochlear implant (CI) in post-meningitic sensorineural hearing loss is, in spite of recent advances in the understanding of the pathogenesis of the condition, still controversial. The danger of labyrinthitis ossificans allows only a little time to decide whether to implant a CI or not. On the other hand the clinician needs to be certain that no residual hearing is present and whether or not the patient will benefit from conventional amplification. A well-documented case of early spontaneous recovery of a profound post-meningitic sensorineural hearing loss in a child is presented and the relevant literature reviewed.
