Abstract:
Objective To investigate the characteristics of distortion products otoacoustic emission (DPOAE) in hepatitis B carriers and chronic hepatitis B patients with normal pure tone results .Methods DPOAE was detected in 29 hepatitis B carriers (58 ears) ,30 chronic hepatitis B patients (60 ears)and 30 normal controls .The three groups had normal pure tone results .The detection rate and amplitude difference of DPOAE at 553～6250 Hz were compared between the two groups .Results The incidence of the DPOAE in HBV carriers for all the frequencies was higher than that in the chronic hepatitis B group ,but there was no significant difference (P>0 .05) .The level of the DPOAE in HBV carriers for all the frequencies was higher than that in chronic hepatitis B group ,and there were significant differences at 1105 ,1560 ,2211 ,3125 ,4416 ,6250 Hz (P<0 .05) ,and at 1560 ,2211 ,6250 Hz(P<0 .01) ,except at 553 ,783 Hz (P>0 .05) .Conclusion There is a potential loss of cochlear functions in the chronic hepatitis B group compared with the HBV carrying group .We suspect that the progress of liver disease is related to the potential hearing loss .
