Insights
Severe bilateral deafness can follow meningitis. Early diagnosis via audiology and Auditory Brainstem Response testing, followed by urgent MRI, is crucial. Bilateral cochlear implantation is recommended for ossification.
Area of Science:
- Otolaryngology
- Neurology
- Pediatrics
Background:
- Bacterial meningitis can lead to severe or profound bilateral deafness.
- The onset of deafness can be immediate or delayed by several months post-meningitis.
- Early diagnosis and intervention are critical for managing post-meningitic hearing loss.
Purpose of the Study:
- To establish a diagnostic pathway for severe or profound bilateral deafness after meningitis.
- To propose evidence-based management guidelines for affected patients.
- To evaluate the role of imaging and audiological tests in diagnosing and managing this condition.
Main Methods:
- Retrospective review of five patients (infants and adolescents) with post-meningitic deafness.
- Audiometry, Behavioral Audiological Testing, and Auditory Brainstem Response (ABR) tests were used for diagnosis.
- Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) were performed to assess cochlear changes.
Main Results:
- Deafness was diagnosed an average of 68.8 days after meningitis.
- MRI revealed endolymph changes in four patients; CT showed ossification in one.
- All five patients underwent bilateral cochlear implantation, with good outcomes in four cases.
Conclusions:
- Bilateral deafness post-meningitis requires prompt diagnostic evaluation, including audiological testing and MRI.
- Urgent MRI is essential to identify endolymph inflammation or ossification.
- Early bilateral cochlear implantation is recommended, especially when ossification is present.
Objectives:
To determine the diagnostic approach to severe or profound bilateral postmeningitic deafness and to propose management guidelines.
Material And Methods:
A retrospective review of five patients (two adolescents and three infants) with rapidly progressive severe bilateral deafness following an episode of meningitis managed between 2004 and 2010.
Results:
The two adolescents presented Neisseria meningitidis meningitis and the three infants presented Streptococcus pneumoniae meningitis. Acquired bilateral deafness was diagnosed by audiometry an average of 68.8 days (range: 9-210) after the episode of meningitis. Behavioural audiological testing, adapted to age and state of health, was performed in all patients. Deafness was confirmed by Auditory Brainstem Response tests. All five patients were assessed by computed tomography (CT) and magnetic resonance imaging (MRI) within ten days. T2-weighted MRI sequences showed endolymph changes in four patients. CT scan demonstrated ossification in only one patient. Bilateral cochlear implant was performed in all patients, with complete electrode array insertion for eight implants and partial insertion for two implants (20 and 21 out of 22 electrodes inserted). Good results were obtained with cochlear implants in four cases.
Conclusions:
Bilateral deafness can occur immediately or several months after bacterial meningitis, regardless of the micro-organism responsible, justifying screening by behavioural audiological testing adapted to age for two years following bacterial meningitis. Auditory Brainstem Response testing can confirm audiometric findings. When severe or profound bilateral deafness is observed, MRI must be performed urgently to detect endolymph inflammation or ossification. Early bilateral cochlear implantation is recommended in the presence of ossification.
