Participants
Forty-two conductive hearing loss (CHL) subjects.
Results: For CHL follow up results: for 1ms group, PTAI showed a better correlation with fs-ABRI (r=0.67, P<.01) with the equation: PTAI=2.15*fs-ABRI-3.49; for 3ms group, PTA showed a better correlation with fs-ABR (r=0.76, P<.01) with the equation PTA=0.93*fs-ABR+3.48. Bland-Altman analysis showed no difference between PTA and fs-ABR in all above analysis. Eustachian tube malfunction would negatively affect the prediction efficacy, for subjects with normal ETF, the correlation between fs-ABRI and PTAI was even higher: PTAI=1.6*fs-ABRI+12.48 with r=0.77 (P=.0407<0.05).
