Summary
Meningitis causes significant childhood deafness, impacting cochlear implant success. While meningitis cases declined in Scotland, cochlear ossification remains a challenge for auditory rehabilitation in affected children.
Area of Science:
- Otolaryngology
- Pediatric Neurology
- Infectious Diseases
Background:
- Meningitis is a leading cause of acquired profound childhood deafness.
- Post-meningitic deafness presents unique challenges for auditory rehabilitation.
- Cochlear implantation is a key intervention for these children.
Purpose of the Study:
- To assess the incidence of post-meningitic deafness in children undergoing cochlear implant assessment.
- To evaluate surgical findings and outcomes in children with post-meningitic deafness.
- To analyze trends in meningitis notifications in Scotland.
Main Methods:
- Retrospective review of patients assessed for cochlear implantation (1989-1999).
- Surgical findings recorded for suitable candidates with post-meningitic deafness.
- Analysis of national meningitis notification data (1988-1998).
Main Results:
- 45 of 550 patients had post-meningitic deafness; 32 were implanted, 12 rejected.
- 10 implanted patients experienced cochlear ossification, hindering device insertion and rehabilitation.
- Meningitis notifications in Scotland showed a declining trend.
Conclusions:
- Post-meningitic deafness significantly affects cochlear implant candidacy and outcomes.
- Cochlear ossification is a notable complication requiring careful surgical consideration.
- Declining meningitis rates may reduce future cases of this type of deafness.
