RESUMEN
INTRODUCTION: Postmeningitis deafness appears in 0-11% of the meningitis cases. Cochlear ossification can develop in these patients, which may make the hearing rehabilitation impossible with cochlear implantation. Due to ossification, it is critical to refer patients to the implant centre without any delay. OBJECTIVE: The aim of this study was to examine the time factor between the appearance of deafness and the first examination in a cochlear implant centre, the possibilities and effectivity of hearing rehabilitation. METHOD: In our tertial referral centre, postmeningitis deafened patients were examined between 2014 and 2022 retrospectively. Hearing results, imaging, possibilities of rehabilitation, complications of cochlear implantations and the hearing results were investigated. RESULTS: 8 patients (3 children, 5 adults) were investigated. The time between the start of deafness and the first appearance varied between 3 weeks to 9 years. Bilateral profound hearing loss was measured in all patients. In 6 cases, cochlear ossification was observed (4 patients bilateral). Cochlear implantation was conducted in 5 patients (4 bilateral, 1 unilateral). In 3 cases, implantation was impossible due to severe ossification. Hearing results showed good hearing levels with poor speech perception in all cases. DISCUSSION: The rehabilitation of severe hearing loss caused by meningitis can present many challenges to clinicians. A critical point in the care is the urgent referral of patients to a cochlear implantation centre as soon as possible after the life-threatening condition has passed. The implementation of further diagnostic and the earliest possible implantation is the responsibility of the implantation centre itself. CONCLUSION: It is recommended to develop a new protocol with the involvement of allied professions to clear patient pathways for an effective treatment strategy. Orv Hetil. 2023; 164(19): 729-738.
