ABSTRACT
OBJECTIVE To study the audiological and etiological characteristics of infants failed to pass hearing screening. METHODS 126 infants received audiological diagnostic tests,including auditory brainstem response(ABR),40 Hz auditory event related potential(40 Hz AERP),distortion product otoacoustic emissions(DPOAE),tympanometry and acoustic reflex. The degrees and types of the hearing loss,and etiological characteristics were analyzed. RESULTS Among 126 infants (252 ears),61 were diagnosed with sensorineural hearing loss(48.41%),48 were conductive hearing loss(38.09%),and 17 were found to have normal ABR thresholds(13.49%). The hearing loss was associated with various factors,including history of infection during pregnancy(21 cases),threatened abortion(9 cases),pregnancy with age at or over 35(6 cases),extension of pregnancy(7 cases),history of systematic diseases(10 cases),history of neonatal jaundice(13 cases),history of asphyxia and hypoxia(18 cases),premature and low birth weight neonates(8 cases),neonatal diseases (8 cases),family history of deafness(5 cases),craniofacial deformity(3 cases),central nervous system disorder(6 cases),and 9 cases were second child. CONCLUSION The infants who failed to pass hearing screening have various etiology characteristics in hearing loss. The infants associated with risk factors were mostly found to have sensorineural hearing loss.
