Abstract: Hearing impairment is the most common complication of meningitis.
This prospective study was designed to determine the prevalence of hearing
impairment after aseptic and bacterial meningitis in children. All patients
5–15 years of age with bacterial or aseptic meningitis admitted in Shiraz
University Hospitals were included in a 40-month period study. Pure tone
audiometry was arranged at the time of discharge. In total, 115 patients were
studied. Sensorineural hearing impairment was detected in 35/83 of aseptic
meningitis patients (42.2%) and 14/32 of bacterial meningitis patients
(46.8%). There were 13 patients with bilateral hearing loss in aseptic
meningitis group and eight patients in bacterial meningitis group (P=0.389).
There were seven patients with moderate to severe hearing loss in
bacterial meningitis group and four patients in aseptic meningitis group (P=0.014).
This study demonstrated high prevalence of sensorineural hearing
impairment following both bacterial and aseptic meningitis. Bilateral hearing
impairment was common in both groups. Hearing impairment was more severe among
bacterial meningitis patients.
