Abstract：Objective To compare bone-conduction ABR and 1000 Hz tympanometry in detecting mild to moderate hearing loss in infants younger than 6 months. Methods Infants younger than 6 months (n=25) who had failed OAE screen-ing, while the external auditory canal was normal and click-ABRs were normal or indicating mild or moderately deafness, were included in this study. The participants were divided into mild and moderate hearing loss groups based on click-ABR results, while those with normal click-ABRs served as controls. All participants received bone-conduction ABR and 1000 Hz tympanometry tests and the difference in detecting conductive hearing loss by the two test modalities was analyzed. Re-sults Bone-conduction ABRs and 1000 Hz tympanometry showed no significant difference in detecting conductive hearing loss (u-test, P>0.05). Conclusion Both 1000 Hz tympanometry and bone-conduction ABR can be used in the diagnosis of conductive deafness in infants younger than 6 months.
