Objective:To investigate the application value of auditory steady-state response (ASSR) combined with short sound auditory brainstem response (ABR) for hearing assessment in children with sensorineural hearing impairment, providing evidence for clinical diagnosis of the disorder.Methods:A total of 90 children with sensorineural hearing impairment who received treatment at Jiaxing Maternity and Child Health Care Hospital from January 2020 to June 2021 were included in this prospective study. These children were randomly divided into a control group and an observation group ( n = 45 per group). The children in the control group underwent ABR testing, while those in the observation group underwent ASSR testing in addition to ABR thresholds testing. The hearing impairment was compared between the two groups. The ABR and ASSR thresholds were compared among children with different degrees of hearing impairment. The correlation between ABR and ASSR at 2 and 4 kHz carrier frequencies was analyzed in the observation group. Results:The abnormal rate of hearing in the observation group was 68.89% (31/45), which was significantly higher than 44.44% (20/45) in the control group ( χ2 = 5.48, P = 0.019). At a carrier frequency of 0.5 kHz, the ASSR thresholds of children with moderate and severe hearing impairment in the observation group were (63.11 ± 6.82) dB nHL and (84.65 ± 5.31) dB nHL, respectively, which were significantly higher than the ABS thresholds (56.12 ± 4.63) dB nHL and (76.87 ± 5.15) dB nHL ( t = 2.94, 2.78, both P < 0.05). There was a positive correlation between ABR and ASSR thresholds at 2 and 4 kHz carrier frequencies in children with different degrees of hearing impairment in the observation group ( r = 0.896, 0.901, both P < 0.05). Conclusion:The combination of ABR and ASSR testings is more accurate in judging the degree of hearing impairment in children with sensorineural hearing impairment than the ABR testing, and can provide a reliable basis for later clinical treatment.
