Objective To evaluate the audiological results of referral infants for failed secondary hearing screening.Methods The audiological results of 210 ears were analyzed.All the referral infants received audiological evaluationin cluding auditory brainstem response (ABR),auditory steady-state response (ASSR),distortion product otoacoustic emission(DPOAE),40 Hz auditory event-related potentials and acoustic impedance.Results Of all the 210 ears,143 were confirmed to have hearing loss with adetection rate of 68.10％ (143/210).Of the confirmed 143 ears,62 ears (43.36％) were conductive and 81 ears (56.64％) were sensorineural.Large vestibular aqueduct syndrome(LVAS) was diagnosed in 16 ears with an incidence of 7.62％ (16/210).Auditory neuropathy spectrum disorder was confirmed in 6 ears with an incidence of 2.85％ (6/210).Conclusions The detection rate of hearing loss is high in infants who have failed secondary hearing screening.We should pay more attention to carry out dynamic follow-up for hearing in infants with high risk factors.Accurate and comprehensive audiological evaluations should be conducted combined with the physiological characteristics of infants.

Objective:To investigate the effects of transient evoked otoacoustic emission (TEOAE) combined with automatic auditory brainstem response (AABR) in high risk newborns hearing screening.Methods:A total of 326 cases of high-risk newborn hearing were examined with TEOAE combined with AABR in NICU,children did not pass by hearing screening were examined with AI,OAE,ABR,40 Hz auditory event related potential(40 Hz AERP).Results:In 21 cases(28 ears) hearing impaired children,TEOAE combined with AABR discovered 16 ears,AABR discovered 18 ears and TEOAE discovered 10 ears.Conclusion:TEOAE combined with AABR in high-risk newborns is more beneficial to early detection of hearing impaired children.
