Abstract

Bacterial meningitis may cause inner ear fibrosis and progressive cochlear ossification with irreversible profound hearing loss (HL). Recognition of potential ossification is essential for effective management.

We present a clinical case of a 4 year old boy who developed a progressive HL starting 3 weeks after meningitis. For the prospective risk of cochlear ossification, bilateral cochlear implantation (CI) was performed. Unexpectedly, unaided hearing threshold began to show improvement on the left ear, starting 4 months after meningitis and continuing for years post CI surgery. In order to explore the residual cochlear function, a trial of exclusively acoustic amplification was performed on the improved left side 5 years post implantation, providing good results.

A certain degree of hearing recovery may be expected after meningitis related deafness. This case encourages surgeons to always adopt atraumatic surgical techniques that can enable the preservation of cochlear structure and residual function after CI surgery.
