Hearing Screening of Primary School Children(girls)

Aim: To identifying type B tympanogramme in hearing impaired children which may be the cause of backwardness in school and to advice the school administration to screen all children. Material and methods: Five hundred and seventy children aged 6-12 years were investigated. Medical history were obtained and otoscopic examination was carried out. Pure tone audiometry and tympanometry were used to detect hearing loss greater than 20 dB HL in the frequency 500Hz, 1000Hz 2000Hz and 4000Hz. Results: Tympanometry ear examination showed 39 (6.84 %) of children suffering from middle-ear problems, and 12 (2.11%) of children with conductive hearing loss. Conclusion: Our findings are consistent with several studies of the prevalence of type B tympanogramme maximum at the age of one, and then decreased until the age of seven and up. Hearing screening and retesting children remains necessary due to high prevalence of hearing loss found in this population and the fluctuating nature of the problem
