Abstract:
Objective To investigate the character 、difference and clinical meaning of distortion product otoacoustic emissions(DPOAE) and auditory brainstem respons(ABR) in high risk neonates with.Methods DPOAE and ABR were recorded with amplaid MK 22 and GSI60 in 200(400ears) high risk neonates, then compared the results.Results Of 200(400ears) newborns, the presence of DPOAE was 64%(256/400 ears), the presence of ABR was 88.25%(353/400 ears). The co-negativity and co-positivity of DPOAE and ABR were 61.50%(246/400 ears)and 9.25%(37/400 ears). The false negative and false positive of DPOAE were 3.91%(10/256 ears)and 74.31%(107/144 ears).Conclusion The DPOAE test is simple,quick,harmless,sensitive and objective. Because it only reflects the function of the cochlea and has high false positive, we can't make the diagnosis of hearing loss immediately when newborns don't pass the DPOAE test.The ABR test is a reliable method for neonatal hearing screening. The combination of DPOAE and ABR in high risk neonatal hearing screening could increase the accuracy and reliability of the test and retest results.
