Objective To investigate the clinical value of auditory brainstem response(ABR)wave Ⅰ latency and 1 000 Hz acoustic immittance in the assessment of middle ear function in infants.Methods A total of 74 infants who were born within 6 months of age from 2020 to 2021 were selected,with a total of 148 ears.According to the click ABR(hereinafter referred to as ABR)threshold,they were divided into mild group(56 ears),moderate group(14 ears)and normal group(78 ears).The ABR wave Ⅰ latency and 1 000 Hz acoustic immittance results were ana-lyzed respectively.Results The Kappa values between ABR wave Ⅰ latency and 1 000 Hz tympanometry in infants of mild and moderate groups were 0.708 and 0.650,respectively.There was no significant difference in the detec-tion rate of middle ear function abnormality(P＞0.05)in infants with mild and moderate threshold impairment within 6 months of age.The paried Chi-square test showed a significant difference between the ABR wave Ⅰ latency and 1 000 Hz acoustic immittance in infants with normal threshold at 6 month of age(P＜0.05),with a Kappa val-ue of 0.297.Conclusion The middle ear function could be evaluated by ABR wave Ⅰ latency or 1 000 Hz acoustic immittance in 6-month-old infants with mild or moderate abnormality.For infants with normal ABR threshold,1 000 Hz acoustic immittance and the latency of ABR wave Ⅰ need to be cross-verified.
