Abstract:
Objective To study the audiometry and otoacoustic emissions in patients with posterior circulation ischemia(PCI) .Methods Forty patients treated by neurologists were selected as the experimental group who re_ceived pure tone audiometry ,tympanometry ,otoacoustic emissions (OAE) and distortion products otoacoustic emis_sions (DPOAE) examinations .Thirty healthy objects were chosen as the control group .The data from the PCI groups and the control group were compared using the SPSS 14 .0 software .ResuIts The difference in pure tone thresholds across 125 to 8 000 Hz between the PCI group and the control group was not statistically significant (P>0 .05) .In the PCI patients ,the prevalence of TEOAE was only 47 .5% ,significantly different from that of in the control group .The prevalence of DPOAE at 0 .5~8 kHz were between 57 .9% ~77 .6% in PCI patients ,and the amplitudes of DPOAE were reduced significantly (P<0 .05) .ConcIusion Cochlear damages can occur to patients with PCI ,especially in the high frequency range .These results suggest that OAE can be used as an important diag_nostic test for patients with PCI ,and might be helpful for the location diagnosis of PCI .
