Abstract

ObjectivePatients with post-meningitis deafness remain challenging candidates for cochlear implantation (CI) which can be difficult due to fibrosis or ossification of the inner ear, and their outcomes remain doubtful. We assessed the surgical and audiological outcomes of CI in patients with profound sensorineural hearing loss caused by meningitis and compared those outcomes to patients without cochlear ossification.MethodsThis retrospective cross-sectional study was carried out at King Fahad General Hospital, Jeddah, Saudi Arabia. Among 246 patients who underwent cochlear implantation, 13 patients with post-meningitic deafness were identified (Group 1). A matched control group, including patients with deafness due to other causes who did not have cochlea osteogenesis, was selected (Group 2). For all patients, data were collected from medical records, including surgical and audiological outcomes.ResultsSclerosis of the cochlea was high in Group 1 (46.2%). There were no postoperative surgical complications in either group. Responses of the auditory nerve action potential obtained through auditory response telemetry (ART) or the neural response telemetry (NRT) were recorded. There was no significant difference between the two groups regarding the intraoperative and the postoperative ART or NRT at selected electrodes representing the entire cochlea. Likewise, no significant difference regarding the speech recognition test (SRT) was detected.ConclusionsCochlear implantation is a safe procedure without surgical complications in post-meningitis patients. Furthermore, early CI in children was associated with favorable outcomes in terms of preservation of the auditory nerve response, restoration of speech discrimination, and recognition to levels comparable to patients with deafness due to other causes. Early audiological assessment in meningitis patients is recommended to identify hearing loss and eventually to offer CI.

Highlights

Cochlear implantation (CI) is the best-accepted modality to rehabilitate adults and children with severe to profound sensory neural hearing loss [1]

Summary

Introduction

Cochlear implantation (CI) is the best-accepted modality to rehabilitate adults and children with severe to profound sensory neural hearing loss [1]. A cochlear implant is an effective procedure that can provide aid to the development of auditory perception, favoring the acquisition of the linguistic processes, especially in children, which will undoubtedly contribute to all aspects of development. Variable factors influence the outcome, e.g., the age of the patient, and the etiology of sensory neural hearing loss (SNHL) (whether congenital or acquired).

The duration of deafness and psychosocial conditions could eventually affect CI outcomes [3]
