Hearing evaluation in children with bacterial meningitis.
Twenty four children with bacterial meningitis were studied prospectively to ascertain the incidence, type and severity of hearing loss. The incidence of sensorineural hearing loss was 20.8%. Patients with hearing loss were followed-up audiologically for six months to find out the progress of hearing impairment. Of the five patients with sensorineural hearing loss only one showed partial recovery while the other three did not show any improvement. Of the five patients with sensorineural hearing loss only one showed partial recovery while the other three did not show any improvement. One patient was lost to follow-up, therefore, recovery was not known. The degree of hearing loss varied form mild to moderate. Antibiotic treatment and laboratory data were analysed to identify the high risk factors predisposing to hearing impairment. The presence of low CSF sugar level, high protein at the initial lumbar puncture and presence of neurological deficits was associated with a significantly higher risk of hearing loss. However, the nature of antibiotic therapy, duration of illness, age and sex of the patients were not significant risk factors in the development of hearing impairment.
