ABSTRACT

Objective To develop the neonatal hearing screening,investigate the incidence and relevant high-risk factors of congenital hearing loss,and explore feasible methods of early screening,diagnosis,following-up and intervention.Methods DPOAE was used for the newborns.The children who failed the tests or had high-risk factors of hearing loss were re-screened using DPOAE and AABR 42 days.ABR was used as the diagnostic test for those who had abnormal results at 3 months,ABR and ASSR were used at 6 months for the second diagnosis.The children with hearing loss were intervened in time,and were arranged for routine following-up and audiological evaluation.Results The normal neonates who failed the first screening was 14.8%,infants with high-risk factors was 21.5%,the large number of normal infants passed re-screening and half of high-risk neonates failed.By analysis of patients who had three-month diagnosis,the incidence of congenital hearing loss was about 2.75‰,and mild-grade,middle-grade,severe,profound was 0.18‰,1.78‰,0.26‰ and 0.53‰ respectively.Conclusion The incidence of congenital hearing loss is the highest in congenital diseases,usual screening is necessary.Questionnaire for high-risk factors of hearing loss must be done;it is very important to follow-up the abnormal infants.
